Event Data Recorders (EDR) ..................................................................................... 108 GENERAL TS 1. Scope Technical specifications define requirements for heavy-duty transit buses, which, by the selection of specifically identified alternative configurations, may be used for both suburban express service and general service on urban arterial streets. Buses have a minimum expected life of twelve (12) years or 500,000 miles, whichever comes first, and are intended for the widest possible spectrum of passengers, including children, adults, the elderly and people with disabilities. TS 2. Definitions Alternative: An alternative specification condition to the default bus configuration. The Agency may define alternatives to the default configuration to satisfy local operating requirements. Alternatives for the default configuration will be clearly identified. Ambient Temperature: The temperature of the surrounding air. For testing purposes, ambient temperature must be between 16°C (50°F) and 38°C (100°F). Analog Signals: A continuously variable signal that is solely dependent upon magnitude to express information content. NOTE: Analog signals are used to represent the state of variable devices such as rheostats, potentiometers, temperature probes, etc. Audible Discrete Frequency: An audible discrete frequency is determined to exist if the sound power level in any 1/3-octave band exceeds the average of the sound power levels of the two adjacent 1/3-octave bands by 4 decibels (dB) or more. Battery Compartment: Low-voltage energy storage, i.e. 12/24 VDC batteries. Battery Management System (BMS): Monitors energy, as well as temperature, cell or module voltages, and total pack voltage. The BMS adjusts the control strategy algorithms to maintain the batteries at uniform state of charge and optimal temperatures. Braking Resistor: Device that converts electrical energy into heat, typically used as a retarder to supplement or replace the regenerative braking. Burst Pressure: The highest pressure reached in a container during a burst test. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 11 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information Capacity (fuel container):The water volume of a container in gallons (liters). Cells: Individual components (i.e., battery or capacitor cells). Code: A legal requirement. Combination Gas Relief Device: A relief device that is activated by a combination of high pressures or high temperatures, acting either independently or together. Composite Container for CNG: A container fabricated of two or more materials that interact to facilitate the container design criteria. Compressed Natural Gas (CNG):Mixtures of hydrocarbon gases and vapors consisting principally of methane in gaseous form that has been compressed for use as a vehicular fuel. Container: A pressure vessel, cylinder or cylinders permanently manifolded together, used to store CNG. Container Appurtenances: Devices connected to container openings for safety, control or operating purposes. Container Valve: A valve connected directly to a container outlet. Curb Weight: Weight of vehicle, including maximum fuel, oil and coolant; and all equipment required for operation and required by this Specification, but without passengers or driver. dBA: Decibels with reference to 0.0002 microbar as measured on the “A” scale. DC to DC Converter: A module that converts a source of direct current from one voltage level to another. Default Configuration Bus: The bus described if no alternatives are selected. Signing, colors, the destination sign reading list and other information must be provided by the Agency. Defueling: The process of removing fuel from a tank. Defueling Port: Device that allows for vehicle defueling, or the point at which this occurs. Destroyed: Physically made permanently unusable. Discrete Signal: A signal that can take only pre-defined values, usually of a binary 0 or 1 nature, where 0 is battery ground potential and 1 is a defined battery positive potential. DPF: Diesel particulate filter. Driver’s Eye Range: The 95th-percentile ellipse defined in SAE Recommended Practice J941, except that the height of the ellipse shall be determined from the seat at its reference height. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 12 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information Energy Density: The relationship between the weight of an energy storage device and its power output in units of watt-hours per kilogram (Wh/kg). Energy Storage System (ESS):A component or system of components that stores energy and for which its supply of energy is rechargeable by the on-vehicle system(engine/regenerative braking/ generator)or an off-vehicle energy source. Fill Pressure for CNG: The pressure attained at the actual time of filling. Fill pressure varies according to the gas temperatures in the container, which are dependent on the charging parameters and the ambient conditions. The maximum dispensed pressure shall not exceed 125 percent of service pressure. Flow Capacity: For natural gas flow, this is the capacity in volume per unit time (normal cubic meters/minute or standard cubic feet per minute) discharged at the required flow rating pressure. Fuel Line: The pipe, tubing or hose on a vehicle, including all related fittings, through which natural gas passes. Fusible Material: A metal, alloy or other material capable of being melted by heat. Fire Resistant: Materials that have a flame spread index less than 150 as measured in a radiant panel flame test per ASTM-E 162-90. Fireproof: Materials that will not burn or melt at temperatures less than 2000°F. Free Floor Space: Floor area available to standees, excluding the area under seats, area occupied by feet of seated passengers, the vestibule area forward of the standee line, and any floor space indicated by manufacturer as non-standee areas, such as the floor space “swept” by passenger doors during operation. Floor area of 1.5 sqft shall be allocated for the feet of each seated passenger protruding into the standee area.

Propulsion System Description The Proterra 40’ Catalyst E2 is a 100% battery electric powered transit bus. Proterra's high- performance ProDrive™ drivetrain maximizes performance and efficiency to meet the challenges of most routes. It consists of three major components; the permanent magnet synchronous traction motor, the power inverter, and the two-speed automated manual transmission where the traction motor and the transmission are the only moving parts. Figure 5-Catalyst ProDrive Propulsion System DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 28 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information The traction motor is capable of 250kW peak power and the traction motor is controlled via an inverter which receives direct current from the high voltage battery system. Both the motor and inverter are liquid cooled. Parameter Specification Peak Power 250 kW Continuous Power 180 kW Peak Torque 900 Nm Continuous Torque 550 Nm Full Power 600 V DC and up Max Speed (full performance) 5500 RPM Table 4-Traction Motor Technical Specifications The unique Proterra two-speed transmission contains a planetary gear set with a pneumatically driven shift mechanism. The transmission is oil-cooled and contains an additional oil cooler to ensure that the transmission remain at ideal temperatures under the most difficult driving cycles. The output of the transmission supplies power to the ZF drop center rear axle. All actuators and sensors for the transmission are connected to the Proterra powertrain controller which controls both the torque/speed commands of the traction motor as well as the transmission shift actuation. These controls have been optimized for transit bus service for best drivability and maximized efficiency. They are designed and calibrated using real world data from customer vehicles, engineering tests utilizing proprietary drive cycles and standard FTA drive cycles (CBD, Arterial, Commuter), and using our high-fidelity simulation tool similar to the model used for fuel economy analysis. With the two-speed transmission Proterra can utilize a smaller, lighter traction motor to meet the needed performance requirements while still offering excellent efficiency. This transmission also allows the powertrain system the flexibility to provide the needed torque while also operating at more efficient traction motor operating points. The combination of the traction motor, the power inverter, and the transmission are a primary rea- son why the Catalyst broke the Altoona records for acceleration, efficiency, and gradeability. TS 9.1 Propulsion Control System The propulsion control system is capable of transmitting and receiving electronic inputs and data from drivetrain components, and broadcasting that data to other vehicle systems. Communication between electronic drivetrain components and other vehicle systems is made using the communications networks. The vehicle system has onboard diagnostic capabilities able to monitor vital motor functions, store and time stamp parameter conditions in memory, and communicate faults and vital conditions to service personnel.

The onboard diagnostic system informs the operator via visual and/or audible alarms when out of parameter conditions exist for vital engine functions. The on-board diagnostic system has capabilities for storing hard and soft codes and processing data and provide detailed information/reports on various aspects of fleet usage. The information is retrievable via cabling or wireless transmission to a laptop. The motor drive protects the drive system against progressive damage. The system monitors conditions critical for safe operation and automatically de-rate power and/or speed and initiate motor shutdown as needed. The on-board diagnostic system triggers a visual and audible alarm to the operator when the motor control unit detects a malfunction and the engine protection system is activated. The propulsion control system is designed with redundancy in mind. For certain failure conditions, a “limp home mode” driving condition is available which enables limited vehicle operation to reduce the need for towing. It is Proterra’s design principle to allow for some level of safe operation if the failure allows. A control is available to the operator to allow a 30-second override, which, when depressed, will allow the operator to delay the drive system shutdown but not the activation and alarm system. TS 9.2 Propulsion System Service The propulsion motor is designed to operate for not less than 300,000 miles without major failure or significant deterioration. Components of the control system are designed to operate for not less than 150,000 miles without replacement or major service. The propulsion system is arranged so that accessibility for all routine maintenance is assured. No special tools, other than dollies and hoists, are required to remove the propulsion system or any subsystems. However, the Agency shall recognize that properly rated test equipment and safe electrical work practices are essential when servicing high voltage components. Proterra will provide all specialty tools and diagnostic equipment required for maintaining the Propulsion System in accordance with Special Tools List.

Energy Storage System The Energy Storage System (ESS) is an integrated system that was designed with safety as top pri- ority. The ESS will be described by the five main sections to this system: 10.1) the battery chemistry, 10.2) the mechanical design, 10.3) the electrical design, 10.4) the con- trol system interacting with the battery system, and 10.5) Energy storage system safety. TS 10.1 Battery Chemistry The Catalyst E2 vehicles utilize a proprietary high-energy density battery chemistry that falls into the broader category of lithium-ion batteries. The high-energy density allows for more on-board en- ergy storage without the need to add battery packs to the passenger cabin or on the roof. The bat- tery cells are provided from a top tier, global EV battery manufacturer that currently supports major automotive and heavy-duty vehicle OEMs. These cells are proven EV batteries that have been ex- tensively tested to validate battery safety, both by the cell manufacturer and by Proterra’s world- class battery engineering team. TS 10.2 Mechanical Design The mechanical design starts with the battery packs themselves and the carbon-fiber reinforced body structure, then continues through to the structure encasing the battery modules and the actual module designs. The bus body incorporates four primary composite stringers that run the length of the body, surrounding the underbody-mounted battery packs between the front and rear axles. Each of these four stringers incorporates full-length, pultruded carbon fiber stringers that maximize strength to weight ratio and add stiffness and rigidity to the battery box surround. It should also be noted that the body serves as a natural electric insulator due to its composite construction vs. a metal chassis normally associated with a transit bus. The vertical location of the battery boxes be- hind these beams is also located below bumper height of most vehicles which provides additional protection from a direct side impact. This location also provides for an extremely low center of grav- ity as well as an ideal weight distribution. Each pack is contained in an aluminum enclosure that is reinforced with 3mm of a heavy-duty poly- urethane spray-on covering that lends individual protection to its sub-components. The pack is de- signed to be sealed to IP66/7 and ANSI/ISE 60529-2004 standards. The pack also fully contains any electrolyte should a cell leak (pursuant to SAE J1766) and meets the 1,000 hours salt spray per ASTM B 117 testing. The packs are designed to handle 5g half-sine peak shock accelerations. The modules within the battery packs are actively cooled to keep the batteries in the ideal temperature range to maximize battery life and comply with the requirements from the battery manufacturer. The battery cooling system includes a chiller integrated with the HVAC system that runs if the ambient environment is too warm for the module manufacturer’s desired system set-points. The battery management system monitors cell voltage, temperature and current to ensure safe performance. Should the cooling system fail, the controls monitor and limit operation as a function of temperature, so that the vehicle will function and de-rate performance safely while indicating a fault to the opera- tor. In this way, a cooling system failure will not result in a hard or immediate stop in operation. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 31 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information Figure 6-Battery Mechanical Design TS 10.3 Battery Thermal Management Battery thermal management is powered whenever the battery contactors are closed. Therefore, the bus in charging mode or on would have all battery thermal functions monitored. Diagnostics monitor the performance of the Battery Thermal Management System, pumps, fan and chiller and will set faults in the event a problem is detected. The batteries will automatically derate (reduce their power output) if they become too hot so that cooling system failures will not damage the batteries. Thermal management has appropriate safety interlocks installed to react to adverse conditions as stated in SAE J1772. Battery temperatures never exceeds the Proterra’s recommended range during operation in the design operating profile and specified ambient conditions. Battery cooling is sufficient to prevent the temperature from exceeding the Proterra’s recommended maximum temperature when the ambient temperature is above 105 degrees F for a period of 16 hours. TS 10.4 Electrical Design The wiring from each pack is insulated and shielded to industry standards and passes into the cen- ter cavity formed between the stringers under the vehicle, referred to as “Broadway”. Broadway provides a protected route the length of the bus back to the high voltage junction box in the rear compartment of the vehicle. This is where the individual batteries are bussed together to provide for one high voltage electrical system. The high voltage interlock circuit and control wires for the bat- tery system run along this route with the high voltage cables for maximum safety. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 32 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information Each battery pack is internally fused and contains a set of contactors. The contactors are located near the pack outputs. Each pack also contains an individual pack controller which serves as a cen- tral hub to gather and report information specific to that pack. Each battery module has a monitoring board that measures voltage of each cell and performs cell balancing. This information is communi- cated to the pack controller via serial communication. TS 10.5 Battery Management System The battery management system (BMS) performs the following functions: A. The BMS system is capable of monitoring the voltage level of cells within each battery pack. The BMS reads and stores individual battery or block voltages at a frequency of 1 data point per block every 15 seconds. The system also monitors battery pack temperatures using no fewer than 2 thermocouples placed in and around each battery pack sampled at the same 4 samples per minute frequency. B. The BMS system is capable of communicating when a battery fault (as defined by Proterra) has occurred and is able to identify and communicate the faulty battery in order to perform maintenance. C. The BMS system is capable of engaging prudent safety interlocks when an unsafe battery condition has been detected. D. The BMS system is able to monitor the battery state-of charge and update a gauge viewed by the operator at least once every 15 seconds. E. The BMS system is able to communicate all data to the bus level information system for storage and communication. TS 10.6 Control System The battery control system is a hierarchical control with the energy storage module (ESM) acting as the interface and lead controller to the rest of the battery system. This module communicates on the main vehicle CAN bus to interface with the cooling, powertrain, charge and other systems. This module can also communicate on the separate battery CAN bus with all of the individual packs. The main controller exchanges information about battery input and output capability as well as cool- ing needs and diagnostic information. The pack controllers control the contactors internal to the pack. They also gather the current infor- mation as well as pack voltage, cell voltage, and temperature information. Pertinent data is pro- vided back to the master controller which uses this information to compute system limits, determine overall health status, and apply system-wide boundaries on use. The system uses algorithms and feedback to know the position of all contactors. The temperature measurements in the pack are re- dundant. There are also additional sensors that perform miscellaneous items like moisture detection in each pack. The battery system algorithms coordinate all activities related to the safety and perfor- mance of the system. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 33 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information The battery control system provides system discharge limits to ensure that the lowest cell never goes below its minimum and that the highest cell never goes above its maximum allowable state. The system is also designed to monitor current imbalances between the packs, temperatures throughout all the packs, moisture, and isolation detection. Should loss of communication occur with a pack or module, the system will gracefully handle this with independent fault actions. TS 10.7 Energy Storage Safety The energy storage system (ESS) is designed and constructed such that occupants will not be ex- posed to hazardous electrical current during normal operation or in the event of an accident as de- fined by ECE80 and APTA TS 23.2 (Crashworthiness). Under normal conditions, the ESS is designed to protect against electric shock per ISO 6469-3. The protection is composed of: -Basic protection measures against direct contact with live parts -All high voltage circuits are rated to IPXXB for direct contact. -Measures for protection under single fault conditions. -The isolation resistance is continuously monitored to ensure adequate isolation. -If the isolation resistance value is less than 500 Ohm/V, a diagnostic event is triggered. -If the isolation resistance value is less than 100 Ohm/V, a diagnostic event is triggered and an indi- cator light is displayed on the dashboard. Each high voltage battery pack utilizes a set of two contactors, independently capable of providing galvanic isolation between Class A and Class B circuits. -The contactors are implemented in a manner to comply with SAE J2929, Section 4.13.1 Protection Against High Voltage Exposure, Automatic Disconnects. •Each high voltage battery pack utilizes a manual service disconnect (MSD). -The MSD is implemented in a manner to comply with SAE J2929, Section 4.13.2 Protection Against High Voltage Exposure, Manual Disconnects.

Charging the Catalyst The 40’ Catalyst E2 comes standard with a single manual charging port located at the rear curb-side of the bus that meets the SAE J1772 CCS Type 1 North American standard for plug-in charging. Additional options are available for dual charge ports located either on each rear side of the bus. The port(s) is capable of charging at 350A continuously. That is the equivalent of 140kW per port assuming a nominal system voltage of 400 VDC. The charge port is capable of supporting charging with a peak voltage of 500 VDC. TS 12. Cooling Systems This vehicle utilizes two independent cooling loops to cool the high-voltage batteries and the power electronics on the vehicle. TS 12.1 Battery Coolant Loop The battery coolant loop has two dedicated coolant pumps that circulate coolant through a battery coolant heater, the battery packs, into the HVAC integrated chiller plate, and back through an inline coolant filter before returning to the coolant pumps. The coolant heater and chiller plate provide heating and cooling, independently, as required to maintain battery temperatures. TS 12.2 Power Electronics Loop The power electronics loop also has a dedicated coolant pump that circulates coolant through the power electronic units that require cooling, through a three fan radiator and then through a strainer to repeat the loop. The transmission is equipped with a standalone oil-to-air cooler mounted next to the transmission. The cooling systems is of sufficient size to maintain the motor, electronics and batteries at a safe, continuous operating temperatures during the most severe operations possible and in accordance with the manufacturers’ cooling system requirements. System temperatures are monitored and the cooling system controlled to ensure equipment temperature is maintained in a safe range. The fan control system is designed with a fail-safe mode of “fan on.” The cooling system meets the requirements stated in the operating environment. The coolant system consists of the following components: Heat Exchanger (Radiator) • Roof mounted (center) • Heat rejection – 20kW o Fluid temp from 140°F to 120°F @ 30 LPM (109°F ambient) • Core size 39” x 17” x 1.6” • Overall size including shroud and fins 48” x 18” x 16” • Variable speed air transfer fans DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 36 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information • Integral side tanks Overflow tank • Accommodates fluid expansion • Incorporates de-aeration feature Coolant transfer pump • Constant speed fluid transfer pump Coolant transfer lines • Rigid coolant tubes – mild steel powder coated (exceeds salt spray corrosion test parameters) TS 12.2.1 Radiator Screen The 40’ Catalyst E2 design does not require a radiator screen. The power electronics loop is equipped with 1 radiator. This radiator, is located on the roof and is effectively screened from large debris which eliminating the need for a radiator screen. It is designed to withstand thermal fatigue and vibration associated with the installed configuration. The radiator cores are easily cleaned with standard pressure-washing equipment. TS 12.2.2 Coolant The 40’ Catalyst E2 is equipped with coolant filtration. The water filter is sized properly with an in- line element and does not contain supplemental coolant additives. TS 12.2.3 Drive Design The 40’ Catalyst E2 is equipped with an electric fan drive bus cooling system. A screen guard is installed on electric motor fans per SAE J1308. TS 12.2.4 Mounting The 40’ Catalyst E2 is equipped with a roof mounted radiator. TS 12.3 Transmission Cooling The transmission is cooled by a dedicated heat exchanger sized to maintain operating fluid within the transmission manufacturer’s recommended parameters of flow, pressure and temperature. The transmission cooling system is separate from the motor cooling system. The transmission cooling system is a standalone system designed to circulate oil through a small radiator next to the transmission (See figure 5). TS 13. Transmission The Proterra Catalyst uses an electronically-controlled pneumatically shifted 2-speed gear box (transmission) provided by Eaton. A torque converter and retarder are not needed. The transmission rated torque, power and speed limits are compatible with the motor capabilities. The transmission is designed to operate for not less than 300,000 miles on a transit bus operating profile without replacement or major service. The transmission is easily replaceable without removing the motor and accessible for service from the underside of vehicle. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 37 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information The controls system is capable of transmitting and receiving electronic inputs and data from other vehicle components through the vehicle CAN network. The control system is powered by the vehicle 24 V distribution system. The control system is responsible for shift execution of the transmission which is done by monitoring powertrain component and driver inputs to select the most appropriate gear. At a minimum, drivetrain components consisting of the motor, transmission and anti-lock braking systems are powered to ensure data communication among components exists when the vehicle ignition is switched to the “on” position. A moderate brake pedal application is required by the driver to engage forward or reverse range from the neutral position to prevent sudden acceleration of the bus from a parked position. The electronically controlled powertrain and vehicle controller has on-board diagnostic capabilities, is able to monitor functions, store and time-stamp out-of-parameter conditions in memory, and communicate faults and vital conditions to service personnel, in coordination with the body controls/diagnostic tool. The transmission contains built-in protection software to guard against severe damage. The on-board diagnostic system triggers a visual alarm to the driver when the electronic control unit detects a malfunction. Although the 2-speed transmission is an automatically shifted unit, it has a manual transmission ar- chitecture, i.e. gears, shafts and shift collars but with no clutches, or torque converter, therefore there is not a need to monitor the fluid on an ongoing basis. The fluid will remain at a constant level between specified fluid change intervals. The oil change frequency recommended for Proterra’s transmission is 100,000 miles. In automotive applications, manual transmissions never require an oil change and thus level indications are not required. The transmission shifts to neutral immediately when the park brake is applied. However, when the parking brake or door brake interlock is active the traction motor is prohibited from applying torque for functional safety requirements. The driver is required to apply the service brake to re-engage forward or reverse gear selection. The door interlock system inhibits vehicle motion by applying the rear brakes until the doors close again. In fact, what happens at zero speed highlights the major dif- ference between Proterra’s EV powertrain and a conventional diesel bus. In a Proterra bus, zero speed means the motor is not spinning. For a diesel bus, the engine still spins at idle so that powertrain requires the torque converter to decouple the engine from the transmission. Proterra’s transmission also does not shift to neutral while the hill hold feature is active. It stays in gear, but the motor is not spinning. When this feature is activated the brake system will lock allow- ing the vehicle to stay stationary. Because the all-electric powertrain is consuming very little power at a complete stop and has no rotation, there is no reason to automatically select neutral when the parking brake or door brake interlock is applied. TS 14. Regenerative Braking The Proterra bus utilizes two main systems to slow down or decelerate the vehicle, a standard pneumatic friction brake system and regenerative braking. Regenerative braking uses the main DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 38 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information traction motor to generate electricity which is then captured and used to charge the main High Volt- age (HV) battery. The ability to capture energy while braking, results in a large improvement in en- ergy efficiency of the vehicle. On a traditional vehicle the energy created during braking is lost to heat through either the friction brake or the retarder. When the driver lifts off the accelerators pedal (zero pedal) ~70% of available regenerative braking torque is automatically applied. The remaining 30% of available regenerative braking is then applied linearly when the driver begins to press on the brake pedal. The pneumatic brakes begin to work linearly with increased brake pedal travel. The feel of the regenerative braking system is similar to a traditional retarder. Regenerative braking is reduced below 3mph to make low speed bus movement smoother. In the event of an ABS or Traction Control event, regenerative braking is automatically disabled until the vehicle comes to a complete stop. At that point it is automatically re-enabled. This is done to ensure vehicle stability in slippery conditions. An efficient driver will be able to drive nearly completely with limited use of the brake pedal and very limited use of the friction brakes. Drivers should anticipate stops and allow regenerative braking to slow the vehicle for maximum energy recapture. TS 15. Mounting All powerplant mounting is mechanically isolated to minimize transfer of vibration to the body structure and provide a minimum clearance of 0.75 in. Mounts control the movement of the powerplant so as not to cause strain in piping and wiring connections to the powerplant. TS 15.1 Service The propulsion system is arranged for ease of access and maintenance. The only special mechanical tool needed for service is a hydraulic lift table for the transmission, motor and battery removal. The air compressor, radiator, all accessories and any other component requiring service or replacement is easily removable and independent of the motor and transmission removal. Since the 40’ Catalyst E2 is equipped with an electric traction motor, there is no exhaust, oil or air intake systems to service. TS 16. Hydraulic Systems Hydraulic system service tasks are minimized and scheduled no more frequently than those of other major coach systems. All elements of the hydraulic system are easily accessible for service or unit replacement. Critical points in the hydraulic system are fitted with service ports so that portable diagnostic equipment may be connected or sensors for an off-board diagnostic system permanently attached to monitor system operation when applicable. Proterra’s standard system has a hydraulic pump which does not include cleanable strainers. The pump is operated by an electric motor, which is controlled by the Motor Controller (Variable Frequency Drive). The pump and motor are non-serviceable assemblies and must be replaced when failed. The only device powered by the hydraulic system is the power steering system. The hydraulic system operates within the allowable temperature range as specified by the lubricant DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 39 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information manufacturer. The hydraulic system is mounted approximately under the driver and is accessible from the outside of the vehicle. The modular system can be removed with four bolts. The supply tank is also mounted external of the vehicle and has a magnet drain plug for ease of service and enables maximum heat dispersion. Our vehicle offers no gauges in the motor compartment. The diagnostic ports on the interior of the vehicle and the diagnostics on the dash allow you to access all systems in order to troubleshoot any issues that are occurring. In addition, we meet the following specs also: - Mean time between repairs >50,000 miles - Max oil temp does not exceed 200°F - Max system working pressure = 2,000 psi - Hoses comply w/ SAE 100R2 / SAE 100R9 / SAE J517 - Hose installation complies w/ SAE J1273 - High pressure hose fittings comply w/ SAE J516 w/ 37° flare - Suction line fluid velocity is under 4 ft/sec - Discharge line fluid velocity is under 25 ft/sec TS 16.1 Fluid Lines All lines are rigidly supported to prevent chafing damage, fatigue failures, degradation and tension strain. Lines are sufficiently flexible to minimize mechanical loads on the components. Lines passing through a panel, frame or bulkhead are protected by grommets (or similar devices) that fit snugly to both the line and the perimeter of the hole that the line passes through to prevent chafing and wear. Pipes and fluid hoses are not bundled with or used to support electrical wire harnesses. Lines are as short as practicable and are routed or shielded so that failure of a line will not allow the contents to spray or drain onto any component operable above the auto-ignition temperature of the fluid. All hoses, pipes, lines and fittings are specified and installed per the manufacturer’s recommendations. The 40’ Catalyst E2 comes standard with EPDM hoses for better securement and reliability. Cooler temperatures provided in an electric bus do not require the use of the more expensive, less reliable silicon hoses. Proterra’s coolant system is regulated to only 13 psi which allows the use ¼” to 1” coolant hose that meet SAE J20R3 and 1.5” coolant hoses that meet SAE J20R1. In addition, SAE J2044 Quick Connects and hose barb fittings are use across the system. TS 16.2 Fittings and Clamps All clamps maintain a constant tension at all times, expanding and contracting with the line in response to temperature changes and aging of the line material. These clamps are manufactured from magni coated carbon spring steel and rated at 1000 hours of salt spray according to ASTM B117. The lines are designed for use in the environment where they are installed. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 40 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information Compression fittings are standardized to prevent the intermixing of components. Compression fitting components from more than one manufacturer are not mixed, even if the components are known to be interchangeable. TS 16.3 Charge Air Piping The lack of an engine precludes the use of a turbocharger is in the 40’ Catalyst E2. TS 17. Radiator Piping The 40’ Catalyst E2 radiator piping is powder-coated steel rated at 1000 hours of salt spray according to ASTM B117. Where practical, hoses are kept to a minimum. Necessary hoses are impervious to all bus fluids. All hoses are secured with constant tension clamps manufactured from magni coated carbon spring steel and rated at 1000 hours of salt spray according to ASTM B117, that provide a complete 360° seal. The clamps maintain a constant tension at all times, expanding and contracting with the hose in response to temperature changes and aging of the hose material. The radiator will be accessible for cleaning and will be easily removable from the bus. TS 18. Oil and Hydraulic Lines Oil and hydraulic lines are compatible with the substances they carry. The lines are designed and intended for use in the environment where they are installed. Lines within the motor compartment are composed of steel tubing where practical, except in locations where flexible lines are required. Hydraulic lines of the same size and with the same fittings as those on other piping systems of the bus, but not interchangeable, are tagged or marked for use on the hydraulic system only. TS 19. Emissions and Exhaust TS 19.1 Exhaust Emissions The 40’ Catalyst E2 is a zero emission vehicle and therefore meets all applicable emission standards. STRUCTURE TS 20. General TS 20.1 Design The structure of the bus is designed to withstand the transit service conditions typical of an urban or intercity duty cycle throughout its service life. The vehicle structural frame is designed to operate with minimal maintenance well beyond the FTA mandated 12-year design operating profile. The 40’ Catalyst E2 has an all-composite, corrosion-proof monocoque body manufactured from high strength materials such as carbon fiber and molded fiberglass with a balsa wood core. The benefits of using the composite body include: a lighter total vehicle weight (reducing the impact to local roads / infrastructure), improved vehicle efficiency and fuel economy, improved thermal and noise reducing properties, exceptional torsional stiffness (resulting in an excellent ride and han- dling), increased durability, corrosion resistance, and best-in-class safety. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 41 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information TS 21. Validation Testing (Including Altoona) Federal Transit Bus Test report number LTI-BT-R1406 documents the performance of the 40-foot Proterra Catalyst BE40 vehicle during its 12 Year / 500,000 miles service-life testing at Altoona. The testing completed in April of 2015 and the final report was published in May 2015. Proterra anticipated excellent performance results for its second-generation 40-foot Catalyst vehicle based on the lessons learned from deploying the 35 foot BE35 EcoRide and given the considerable amount of design engineering that went into the vehicle. For instance, Proterra’s vehicle design team was able to reduce the vehicle weight by over 1,000lbs on a vehicle that is six (6) feet longer than its predecessor. The Catalyst vehicle didn’t disappoint, breaking Altoona records for efficiency, gradeability, weight and acceleration. While conventional diesel buses average 3.86 MPG, the Proterra Catalyst achieved the best efficiency rating ever for a 40-foot transit bus at 1.7kW/mi (or 22 MPGe). Nearly six times more efficient than a diesel or CNG bus, the Catalyst is also more energy efficient per mile than other electric buses that have been through the same tests. The end result is that operating Proterra buses translates to a lower lifetime energy consumption. Gradeability has been a historic obstacle for electric buses, which until now, weighed more and had less power, making steep inclines difficult if not impossible to climb. The Catalyst conquered a 15.5% grade, unprecedented in this test by an electric bus. Also, due to the composite nature of the bus body, Proterra’s curb weight was measured at only 27,370lbs, meaning that the Proterra Cata- lyst is not only lighter than any other electric bus (leading to greater efficiency), but also more dura- ble than buses made of aluminum or steel and less prone to corrosion. As proof of the vehicle’s su- perior power-to-weight ratio, the Proterra 40′ Catalyst also achieved 0-20 acceleration in just 6.7 seconds. TS 21.1 Post-Altoona Upgrades Since the testing at Altoona, Proterra has used the test results as they are intended, to improve the design and reliability of our 40-foot Catalyst vehicle. Most items noted in the Altoona report have since received a design update in order to improve the areas that failed. While the sole Class 2 fail- ure is explained in greater detail below, we stand ready to review any and all details from the report if the agency so desires. The 40-foot Catalyst bus experienced a class 2 failure of the vertical wall where the rear suspension bracket, which mounts the four-bar suspension, is attached. The vertical wall failed in the area where it was molded to the bottom surface of the body. The extended downtime noted in the Al- toona report is attributed to the time it took to complete the root cause analysis, which involved physical inspections of the failure, independent reviews by a third-party engineering firm, and failure reviews by the body supplier relative to their initial Finite Element Analysis (FEA). The result of the root cause investigation was that the composite structure in this area was incorrectly manufactured by Proterra’s body supplier. The composition of the composite body (referred to as the “laminate schedule”) design for the body structure was improved based on results of the root cause analysis. An updated laminate schedule DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 42 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information was developed, validated via physical testing, and then retrofitted to the Altoona test bus in the fail- ure area in order to sustain the applied loads. As a result, the Altoona test bus was returned to the test track and successfully completed the remaining Altoona testing with no further composite body issues. After the successful completion of the Altoona test, Proterra’s body supplier retrofitted the bodies which had been previously delivered and updated the laminate schedule for all future pro- duction buses. To stand by the performance of the Proterra Catalyst design, Proterra includes a standard warranty for 12 years or 500,000 miles against defects pertaining to the composite body structure. TS 21.2 Altoona Testing for the 40’ Catalyst E2 As identified in 49 CFR 665.11 - Testing requirements (d), because the 40’ Catalyst BE40 has pre- viously been tested at Altoona, but since the E2 variant of the vehicle has an upgraded Energy Storage System (ESS),constituting “a major change in chassis or components”, the E2 variant re- quired partial testing in place of full testing. The testing was completed in August of 2017 and the final report was published in September 2017. The 40’ Catalyst E2 completed the Performance and Fuel Economy segments of the full Altoona testing after the bus check-in. The 40’ Catalyst E2 vehicle now boasts the industry’s longest operat- ing range documented at Altoona, 203.8 miles on a Heavy-Duty Urban Dynamometer Driving Schedule (HD-UDDS), besting prior Altoona-recorded ranges from competing electric buses of 87.01 miles and 128.6 miles. Please note that Proterra is currently transitioning to a larger front axle (ZF Model RL82 EC with an 8200kg / 18,078lbs GAWR) to address the potential front axle overweight issue noted in the Altoona report. Add advantage to new axle or section where advantages are TS 21.3 Structural Validation Prior to acceptance of first bus, the vehicle will have completed any FTA-required Altoona testing. Any items that required repeated repairs or replacement will undergo corrective action with support- ing test and analysis. A report clearly describing and explaining the failures and corrective actions taken to ensure that any and all such failures will not occur will be submitted to the Agency. The Altoona Test Report will be provided at the request of the Agency. TS 21.4 Post Testing In 2016, a Proterra Catalyst vehicle completed 4-Post Durability Testing at Exova Defiance in Michi- gan. The purpose of the test was to validate the vehicle design over a simulated 750,000 miles. The testing is broken up into six segments, each representing 125,000 miles of service and taking ap- proximately 25 days to complete. Overall the bus spent 8 months completing the 4-post testing. While we learned a great deal about the durability of components attached to the body structure (e.g. air bags, etc.), the composite body did not disappoint, with no structural or body issues noted during the simulated 18-year testing (no Class 2 failures and the handful of Class 3 failures reme- died at the beginning of the test). In general, all our major manufacturing processes and engineer- ing designs were validated to 50% past the FTA mandated service life of vehicle.

Figure 7-Catalyst 4-Post Durability Test TS 22. Distortion The bus, loaded to GVWR and under static conditions, did not exhibit deflection or deformation that impairs the operation of the steering mechanism, doors, windows, passenger escape mechanisms or service doors. Static conditions include the vehicle at rest with any one wheel or dual set of wheels on a 6 in. curb or in a 6 in. deep hole. TS 23. Resonance and Vibration All structure, body and panel-bending mode frequencies, including vertical, lateral and torsional modes, are sufficiently removed from all primary excitation frequencies to minimize audible, visible or sensible resonant vibrations during normal service. TS 23.1 Motor Compartment Bulkheads The passenger and motor compartment are separated by fire-resistant bulkheads. This bulkhead shall preclude or retard propagation of an motor compartment fire into the passenger compartment and is in accordance with the Recommended Fire Safety Practices defined in FTA FMVSS 302. There is no access panel from inside of the bus that allows for anyone to reach the ProDriver. Harnesses have connectors at the bulkhead and we don't have engine access panels. Only necessary openings are allowed in the bulkhead, and these are fire-resistant. Climate controlled air does not pass through the motor compartment. Wiring passing through the bulkhead use connectors or other means to prevent or retard fire propagation through the bulkhead. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 44 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information TS 23.2 Crashworthiness Regarding the body’s best-in-class safety and structural rigidity, a Finite Element Analysis (FEA) was completed in order to ensure the bus body and roof structure will withstand a static load equal to 150 percent of the curb weight evenly distributed on the roof with no more than a 6 in. reduction in any interior dimension. Windows will remain in place and will not open under such a load. These requirements are met without the roof-mounted equipment installed. The finite element analysis shows the bus will withstand a 25 mph impact by a 4000lb automobile at any side, excluding doorways, along either side of the bus with no more than 3 in. of permanent structural deformation at seated passenger hip height. This impact will not result in sharp edges or protrusions in the bus interior. The finite element analysis shows the body below 35 in. from ground level will withstand a static load of 2000 lbs applied perpendicular to the bus by a pad no larger than 5 sq in. This load will not result in deformation that prevents repair of the body to the original appearance of the bus. Reports are available upon request. TS 24. Corrosion The bus flooring, sides, roof, understructure and axle suspension components are designed to resist corrosion or deterioration from atmospheric conditions and de-icing materials for a period of 12 years or 500,000 miles, whichever comes first. It will maintain structural integrity and nearly maintain original appearance throughout its service life, with the Agency’s use of proper cleaning and neutralizing agents. All materials that are not inherently corrosion resistant are protected with corrosion-resistant coatings. All joints and connections of dissimilar metals are corrosion resistant and are protected from galvanic corrosion. The metallic structural components under the bus body (ProDrive, Axles) are first electrocoated (e-coated), then powder-coated to ensure maximum corrosion protection to meet the 1,000 hour ASTM B117 requirement with no red rust or weight loss. This provides a superior corrosion protection when compared to zinc chromate or zinc phosphate prime paints. There are no roll cage under the bus, but any tubes under body are e-coated then powder coated so inner surface is protected. Representative samples of all materials and connections withstand a two-week (336-hour) salt spray test in accordance with ASTM Procedure B-117 with no structural detrimental effects to normally visible surfaces and no weight loss of over 1 percent. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 45 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information The 40’ Catalyst E2 body is manufactured from a composite material consisting of high strength fiberglass, carbon fiber in high stress areas that is infused with resin. Sub frames for the front and rear suspension are manufactured from high-strength low-alloy (HSLA) steel that is E-coated and powder-coated. The combination of composite body and treated sub frames yields an entire vehicle which is corrosion resistant. TS 25. Towing Each towing device withstands, without permanent deformation, tension loads up to 1.2 times the curb weight of the bus within 20° of the longitudinal axis of the bus. The rear towing device(s) will not provide a toehold for unauthorized riders. The method of attaching the towing device will not require the removal, or disconnection, of front suspension or steering components. Shop industrial type air connectors are provided at the front and rear street side of the bus and are capable of supplying all pneumatic systems of the bus with externally sourced compressed air. The location of these shop air connectors facilitate towing operations. A plug connector permanently mounted at the front of the bus provides for bus tail lamp, marker, stop and turn signal lamp operation as controlled from the towing vehicle. The connector includes a spring-loaded dust- and water-resistant cap. The front towing devices allow attachment of adapters for a rigid tow bar and permit the lifting and towing of the bus, at curb weight, while the front wheels are clear off the ground. These devices also permit common flat towing. Two rear recovery devices/tie downs do not permit the lifting of the bus to the extent where the rear wheels are lifted off the ground. The method of attaching the tow bar or adapter requires the specific approval of the Agency. Any tow bar or adapter exceeding 50 lbs will have means to maneuver or allow for ease of use and application. Each towing device accommodates a crane hook with a 1 in. throat. Upon request, the 40’ Catalyst E2 vehicle can be manufactured with additional support permitting the lifting and towing of the bus for a short distance, such as in cases of an emergency, to allow access to provisions for front towing of bus. TS 26. Jacking It is possible to safely jack up the bus, at curb weight, with a common 10-ton floor jack with or without special adapter, when a tire or dual set is completely flat and the bus is on a level, hard surface, without crawling under any portion of the bus. Jacking from a single point permits raising the bus sufficiently high to remove and reinstall a wheel and tire assembly. Jacking pads located on the axle or suspension near the wheels permits easy and safe jacking with the flat tire or dual set on a 6 in. high run-up block not wider than a single tire. The bus withstands such jacking at any one or any combination of wheel locations without permanent deformation or damage. Jacking pads are painted safety yellow and decals are applied to identify locations. The locations shown below are the Proterra recommended jacking locations: DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 46 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information Figure 8-Proterra Recommended Jacking Points TS 27. Hoisting The bus axles or jacking plates accommodate the lifting pads of a two-post hoist system. Jacking plates, if used as hoisting pads, are designed to prevent the bus from falling off the hoist. Other pads or the bus structure supports the bus on jack stands independent of the hoist. The vehicle is capable of being lifting by the wheels. The locations shown below are the Proterra recommended hoisting locations: The bus may be picked up by the following locations, but MUST have a surface area of no less than 5 square inches per mounting pad that contacts the bus body. The zones shown below are ac- ceptable lifting areas: Figure 9-Proterra Recommended Lifting Zones TS 28. Floor TS 28.1 Design The floor is essentially a continuous plane, except at the wheel housings and platforms. Where the floor meets the walls of the bus, as well as other vertical surfaces such as platform risers, the surface edges are blended with a circular section of radius not less than ¼ in. or installed in a fully sealed butt joint. Similarly, a molding or cover prevents debris accumulation between the floor and DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 47 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information wheel housings. The vehicle floor in the area of the entrance and exit doors has a lateral slope not exceeding 2° to allow for drainage. The floor design consists of two levels (bi-level construction). Aft of the rear door extending to the rear settee riser, the floor height is not raised to a height more than 21 in. above the lower level, with equally spaced steps. An increase slope does not to exceed 3.5° off the horizontal. TS 28.2 Strength The floor deck is integral with the basic structure and designed to last the life of the bus. Sheet metal screws are not used to retain the floor, and all floor fasteners are serviceable from one side only. Any adhesives, bolts or screws used to secure the floor to the structure will last and remain effective throughout the life of the coach. All floor fasteners are secured and protected from corrosion for the service life of the bus. The floor deck is reinforced as needed to support passenger loads. At GVWR, the floor will have an elastic deflection of no more than 0.60 in. from the normal plane. The floor withstands the application of 2.5 times gross load weight without permanent detrimental deformation. The floor, with coverings applied, withstands a static load of at least 150 lbs applied through the flat end of a ½ in. diameter rod, with 1/32 in. radius, without permanent visible deformation. TS 28.3 Construction Proterra’s 40’ Catalyst™ E2 composite floor is integral with the basic structure and consists of the subfloor and the floor covering that will last the life of the bus. The floor as assembled, including the sealer, attachments and covering, is waterproof, non-hygroscopic and resistant to mold growth. The subfloor is resistant to the effects of moisture, including decay (dry rot). It is impervious to wood-destroying insects such as termites. TS 29. Platforms TS 29.1 Driver’s Area The covering of platform surfaces and risers, except where otherwise indicated, are the same material as specified for floor covering. Trim is provided along top edges of platforms unless integral nosing is provided. TS 29.2 Driver’s Platform The APTA specification requires the driver’s platform to be of a height such that, in a seated position, the driver can see an object located at an elevation of 42 in. above the road surface, 24 in. from the leading edge of the bumper. With a 5th percentile female at the lowest seated position, there is a section of the top of the dash that is 20 inches wide where the object could not be seen. The platform height does not position the driver such that the driver’s vertical upward view is less than 15°. A warning decal is provided to alert the driver to the change in floor level. Figure 10 illustrates the means by which this requirement was determined.

If required by the Agency, the farebox will be mounted on a platform of suitable height to provide accessibility for the driver without compromising passengers’ access. Stanchions are located around the farebox. TS 29.4 Rear Step Area to Rear Area The vehicle is a bi-level floor design. A rear step area is provided along the center aisle of the bus to facilitate passenger traffic between the upper and lower floor levels. This step area is cut into the rear platform and is approximately the aisle width, a minimum 12 in. deep and approximately half the height of the upper level relative to the lower level. The horizontal surface of this platform is covered with skid-resistant material with a visually contrasting nosing and is sloped slightly for drainage. A warning decal or sign is provided at the immediate platform area to alert passengers to the change in floor level. TS 30. Wheel Housing TS 30.1 Design and Construction Sufficient clearance and air circulation is provided around the tires, wheels and brakes to preclude overheating when the bus is operating on the design operating profile. Wheel housings are constructed of corrosion-resistant and fire-resistant material. Wheel housings, as installed and trimmed, withstand impacts of a 2in. steel ball with at least 200 ft- lbs of energy without penetration. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 49 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information Interference between the tires and any portion of the bus is not possible in maneuvers up to the limit of tire adhesion with weights from curb weight to GVWR. Wheel housings are adequately reinforced where seat pedestals are installed. Wheel housings have sufficient sound insulation to minimize tire and road noise and meet all noise requirements of this specification. Design and construction of front street side wheel housings allows for the installation of a radio or electronic equipment storage compartment on the interior top surface. Design and construction of front curb side wheel housings allows its use as a luggage rack. The finish of the front wheel housings is scratch-resistant and complement interior finishes of the bus to minimize the visual impact of the wheel housing. The wheel housings are color-impregnated to match interior finishes. The lower portion extending to approximately 10 to 12 in. above the floor is equipped with scuff-resistant coating or stainless steel trim. Wheel housings not equipped with seats or equipment enclosure have a horizontal assist mounted on the top portion of the housing no more than 4 in. higher than the wheel well housing. The wheel housing are designed to have the ability to chain buses. CHASSIS TS 31. Suspension TS 31.1 General Requirements The front and rear suspensions are pneumatic type, with a heavy-duty ZF Independent Front Suspension (IFS). It has a smaller turning radius them typical transmissions, better ride quality, improved vehicle handling, higher roll stiffness, and less load on road surface by reducing unsprung masses. The basic suspension system will last the service life of the bus without major overhaul or replacement. Adjustment points are minimized and will not be subject to a loss of adjustment in service. Routine adjustments are easily accomplished by limiting the removal or disconnecting the components. TS 31.2 Alignment All axles are properly aligned so the vehicle tracks accurately within its size and geometry of the. TS 31.3 Springs and Shock Absorbers TS 31.3.1 Suspension Travel The suspension system permits a minimum wheel travel of 2.75 in. jounce-upward travel of a wheel when the bus hits a bump (higher than street surface), and 2.75 in. rebound-downward travel when the bus comes off a bump and the wheels fall relative to the body. Elastomeric bumpers are provided at the limit of jounce travel. Rebound travel is limited by elastomeric bumpers or hydraulically within the shock absorbers. The suspensions incorporates Smart Air Management Systems (SAMS) for automatic height control so that regardless of load the bus height relative to the centerline of the wheels does not change more than ½ in. at any point from the height required. The safe operation of a bus will not be impacted by ride height up to 1 in. from design normal ride height. The SAMS system is able to raise and lower the chassis while moving at slow speeds, can DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 50 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information automatically control the ride height of vehicle during normal road use resulting in a smoother ride and has built-in diagnostics TS 31.3.2 Damping Vertical damping of the suspension system is accomplished by hydraulic shock absorbers mounted to the suspension arms or axles and attached to an appropriate location on the chassis. Damping is sufficient to control coach motion to three cycles or less after hitting road perturbations. The shock absorber bushing is made of elastomeric material that will last the life of the shock absorber. The damper incorporates a secondary hydraulic rebound stop. TS 31.3.3 Lubrication All elements of steering, suspension and drive systems requiring scheduled lubrication will be provided with grease fittings conforming to SAE Standard J534. These fittings are located for ease of inspection and are accessible with a standard grease gun from a pit or with the bus on a hoist. Each element requiring lubrication has its own grease fitting with a relief path. The lubricant specified shall be standard for all elements on the bus serviced by standard fittings and is required no less than every 6000 miles. TS 31.3.4 Kneeling A kneeling system lowers the entrance(s) of the bus a minimum of 2.5 in. during loading or unloading operations regardless of load up to GVWR, measured at the longitudinal centerline of the entrance door(s) by the driver. The kneeling control provides the following functions: • Downward control must be held to allow downward kneeling movement. • Release of the control during downward movement will completely stop the lowering motion and hold the height of the bus at that position. • Upward control actuation allows the bus to return to normal floor height without the driver having to hold the control. The brake and throttle interlock prevents movement when the bus is kneeled. The kneeling control is disabled when the bus is in motion. The bus kneels at a maximum rate of 1.25 in. per second at essentially a constant rate. After kneeling, the bus will rise within 4 seconds to a height permitting the bus to resume service and will rise to the correct operating height within 7 seconds regardless of load up to GVWR. During the lowering and raising operation, the maximum vertical acceleration will not exceed 0.2g, and the jerk will not exceed 0.3g/second. An indicator visible to the driver is illuminated until the bus is raised to a height adequate for safe street travel. An audible warning alarm will sound simultaneously with the operation of the kneeler to alert passengers and bystanders. A warning light mounted near the curbside of the front door with minimum 1.75 in. diameter amber lens, is provided that will blink when the kneel feature is activated. Kneeling will not be operational while the wheelchair ramp is deployed or in operation.

Wheels and Tires TS 32.1 Wheels All wheels are interchangeable. Standard configuration wheels are compatible with standard configuration tires in size and load-carrying capacity. Front wheels and tires are balanced as an assembly per SAE J1986. The standard configuration includes brushed-aluminum finish ALCOA 22.5 in. x 9 in. Wheels. Additional finishes are available upon request. TS 32.2 Tires Tires are suitable for the conditions of transit service and sustained operation at the maximum speed capability of the bus. Load on any tire at GVWR will not exceed the tire supplier’s rating. Sufficient space is not provided to allow the Agency to carry a spare tire. The tire size for the Catalyst E2 buses is 315/80R22.5. If the tires will be provided by the customer, please coordinate tire selection in order to provide ample weight ratings for the front axle at full standing and seating capacity. TS 33. Steering Hydraulically assisted steering is provided. The steering gear is an integral type with the number and length of flexible lines minimized or eliminated. Power steering hydraulic pump is electrically driven. TS 33.1 Steering Axle The ZF front axle is an independent suspension design, non-driving, with a load rating sufficient for the bus loaded to GVWR and is equipped with grease type front wheel bearings and seals (figure Figure 11-Proterra ZF front axle DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 52 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information All friction points on the front axle are equipped with replaceable bushings or inserts and, if needed, lubrication fittings easily accessible from a pit or hoist. The steering geometry of the outside (frontlock) wheel is within 2° of true Ackerman up to 50 percent lock measured at the inside (backlock) wheel. The steering geometry is within 3.5° of true Ackerman for the remaining 100 percent lock measured at the inside (backlock) wheel. TS 33.2 Steering Wheel TS 33.2.1 Turning Effort Steering effort is measured with the bus at GVWR, stopped with the brakes released on clean, dry, level, commercial asphalt pavement and the tires inflated to recommended pressure. Under these conditions, the torque required to turn the steering wheel 10° is no less than 5 ft-lbs and no more than 10 ft-lbs. Steering torque may increase to 70 ft-lbs when the wheels are approaching the steering stops, as the relief valve activates. Power steering failure will not result in loss of steering control. With the bus in operation, the steering effort will not exceed 55 lbs at the steering wheel rim, and perceived free play in the steering system will not materially increase as a result of power assist failure. Gearing will require no more than seven turns of the steering wheel lock-to-lock. Caster angle will be selected to provide a tendency for the return of the front wheels to the straight position with minimal assistance from the driver. TS 33.2.2 Steering Wheel, General The steering wheel diameter is available in either 18 in or 20 in.; the rim diameter is ⅞ to 1¼ in. and shaped for firm grip with comfort for long periods of time. Steering wheel spokes and wheel thickness ensures visibility of the dashboard so that vital instrumentation is clearly visible at center neutral position (within the range of a 95th-percentile male, as described in SAE 1050a, Sections 4.2.2 and 4.2.3). Placement of steering column is as far forward as possible, and in line with the instrument cluster. TS 33.2.3 Steering Column Tilt The steering column has full tilt capability with an adjustment range of no less than 40° from the vertical. It is easily adjustable by the driver and accessible by a 5th percentile female and 95th percentile male. TS 33.2.4 Steering Wheel Telescopic Adjustment The steering wheel has full telescoping capability and has a minimum telescopic range of 1.91 in. and a minimum low-end adjustment of 29 in., measured from the top of the steering wheel rim in the horizontal position to the cab floor at the heel point.

Brakes TS 36.1 Service Brake Proterra’s 40’ Catalyst™ E2 is equipped with self-adjusting disc brakes on the four wheel ends manufactured by Knorr-Bremse. The brakes are equipped with a rubber bush with axial ribbing (see figure 14 arrow H). The pads/disc wear can be visually determined without removing the wheel, by noting the position of the wear marker point see arrow G, the change-over point from the ribbed to the smooth surface (see Figure 14). Figure 14-Dimension C with new disc and brake pads DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 55 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information If dimension C is less than 1 mm, the brake pad thickness and brake disc must be checked with the wheel removed (see Figure 15). Figure 15-Dimension C with worn disc/brake pads If any minimal tolerance limits have been reached the pads and/or disc must be changed. TS 36.2 Actuation Service brakes are controlled and actuated by a compressed air system. Force to activate the brake pedal control is an essentially linear function of the bus deceleration rate and will not exceed 75 lbs at a point 7 in. above the heel point of the pedal to achieve maximum braking. The heel point is the location of the driver’s heel when his or her foot is rested flat on the pedal and the heel is touching the floor or heel pad of the pedal. The ECU for the ABS system is protected, yet in an accessible location to allow for ease of service. Microprocessor controlled automatic traction control (ATC) is provided. TS 36.3 Friction Material The brake linings are made of non-asbestos material. In order to aid maintenance personnel in determining extent of wear, brakes are equipped with a rubber bush with axial ribbing as specified at TS 36.1 indicating the thickness C (see figure 15) at which replacement becomes necessary is provided on each brake lining. TS 36.4 Hubs and Drums/Discs Replaceable wheel bearing seals are run on replaceable wear surfaces or are of an integral wear surface sealed design. Wheel bearing and hub seals and unitized hub assemblies will not leak or weep lubricant when operating on the design operating profile for the duration of the initial manufacturer’s warranty. The bus is equipped with disc brakes on all axles, and the brake discs allow machining of each side of the disc to obtain smooth surfaces per manufacturer’s specifications. The brake system material and design was selected to absorb and dissipate heat quickly so that the heat generated during braking operation does not glaze the brake linings. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 56 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information TS 36.5 Parking/Emergency Brake The parking brake is a spring-operated system, actuated by a valve that exhausts compressed air to apply the brakes. The parking brake may be manually enabled when the air pressure is at the operating level per FMVSS 121. The parking brake valve button will pop out when air pressure drops below requirements of FMVSS 121. An emergency brake release is provided to release the brakes in the event of automatic emergency brake application. The driver can manually depress and hold down the emergency brake release valve to release the brakes and maneuver the bus to safety. Once the driver releases the emergency brake release valve, the brakes engage to hold the bus in place. Air to the emergency brake release system is provided by a dedicated emergency air tank. TS 37. Interlocks TS 37.1 Passenger Door Interlocks To prevent opening rear passenger doors while the bus is in motion, a speed sensor is integrated with the door controls to prevent the rear door from being enabled or opened unless the bus speed is less than 2 mph. To preclude movement of the bus, an accelerator interlock locks the accelerator in the closed position, and a brake interlock engages the service brake system to stop movement of the bus when the driver’s door control is moved to an open position, or the rear door panel is opened more than 3 in. from the fully closed position (as measured at the leading edge of the door panel). The interlock engagement brings the bus to a smooth stop and will be capable of holding a fully loaded bus on a 6 percent grade, until the interlocks are released. These interlock functions are active whenever the vehicle master run switch is in any run position. All door systems employing brake and accelerator interlocks are supplied with supporting failure mode effects analysis (FEMA) documentation, which demonstrates that failure modes are of a failsafe type, thereby never allowing the possibility of release of interlock while an interlocked door is in an unsecured condition, unless the door master switch has been actuated to intentionally release the interlocks. The brake interlock regulator is non-adjustable. As an option, an accelerator interlock locks the accelerator in the closed position, and a brake interlock engages the service brake system to stop movement of the bus whenever front doors are open. TS 38. Pneumatic System TS 38.1 General The bus air system operates the air-powered accessories and the braking system with reserve capacity. New buses will not leak down more than 5psi over a 15-minute period of time as indicated on the dash gauge.

The compressor discharge line between power plant and body-mounted equipment is a flexible Teflon hose with a braided stainless steel jacket. Other lines necessary to maintain system reliability are flexible Teflon hose with a braided stainless steel jacketed fittings. They use standard SAE or JIC brass or steel, flanged, swivel-type fittings. Braided flexible hoses are as short as practicable and individually supported. They will not touch one another or any part of the bus except for the supporting grommets. Flexible lines are supported at 2ft intervals or less. Air lines are clean before installation and are installed to minimize air leaks. All air lines are routed to prevent water traps to the extent possible. Grommets or insulated clamps protect the air lines at all points where they pass through understructure components. TS 38.4 Air Reservoirs All air reservoirs meet the requirements of FMVSS Standard 121 and SAE Standard J10 and are equipped with drain plugs and guarded or flush type drain valves. Major structural members protect these valves and any manual moisture ejector valves from road hazards. Reservoirs are sloped toward the drain valve. All air reservoirs have drain valves that discharge below floor level with lines routed to eliminate the possibility of water traps and/or freezing in the drain line. The Proterra Catalyst uses a single analog needle to display the lowest air pressure in both the primary and secondary reservoirs instead. The single air pressure gauge displays the lowest pressure of the two systems. Our system does not use pressure regulators (except for pneumatic doors). Our controls regulate our pressure and all 3 pressures (primary, secondary, & aux) can be read at the dash.

The air dryer system includes one or more replaceable desiccant cartridges. The 40’ Catalyst E2 comes standard with a Bendix AD-IS air dryer. A provision for an additional oil separator is not provided. ELECTRICAL, ELECTRONIC AND DATA COMMUNICATION SYSTEMS TS 39. Overview The vehicle control system is based around a vehicle controller from Continental VDO with KIBES- 32 firmware developed for heavy duty vehicles. The Continental VDO vehicle control system is based around several hardware components. The ZR-32A is the master controller and contains all the functionality software that controls the main ve- hicle components. The multiplexing units distribute the master controller’s needed discreet and an- alog inputs and outputs to convenient locations around the vehicle. The fully integrated driver’s in- strument cluster contains all needed gauge dials and tell tales. Additionally the instrument cluster includes a high performance digital display that is used to inform the driver of various system states including additional driver tell-tale indications, overhead charging instructions and diagnostic infor- mation. The ZR-32A controller is based on two, 32-bit RISC processors with internal 1024kB flash for pro- gram memory and SRAM for data parameter storage. It can run 5 independent data networks, at speeds up to 500kB/s based on the CAN J1939 architecture. The CAN (Controller Area Network) is a high-integrity serial data communications bus for real-time applications governed by ISO 11898 and has safety-agency approval for passenger vehicle control. The MUX-2B units run on an 8-bit processor, having internal programming memory and are equipped with 24 quasi-analog status inputs, 6 dedicated analog inputs, and 32 digital outputs with internal fault detection and protection. The digital outputs are organized in sub groups to be able to run sets of independent systems (i.e., 12V loads as well as 24V loads including outputs that have current capacity up to 10 amps). The utilized networks are: • PCAN: Used for high-performance systems like the Traction Motor, cooling System, bat- tery management and ABS. • MCAN: Used for the multiplexing units that distribute the master controller’s needed dis- crete and analog inputs and outputs to convenient locations around the vehicle. • ICAN: Used for interfacing with the driver’s instrument cluster including the digital display screen. This network includes communicating the discreet input/outputs available from the instrument cluster as well as controlling the clusters dial gauges, tell-tales and what is displayed on the digital display. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 60 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information TS 39.1 Modular Design Design of the electrical, electronic and data communication systems are modular so that each electronic device, apparatus panel, or wiring bundle is easily separable from its interconnect by means of connectors. Power plant wiring is an independent wiring harness. Replacement of the ProDrive compartment wiring harnesses does not require pulling wires through any bulk head or removing any terminals from the wires. As an exception, there is a multicore cable that runs from the ProDrive to the power steering motor at the front of the vehicle. This cable passes through 2 bulkheads and is part of a ProDrive harness. TS 40. Environmental and Mounting Requirements The electrical system and its electronic components are capable of operating in the area of the vehicle in which they will be installed, as recommended in SAE J1455. Electrical and electronic equipment are not located in an environment that will reduce the performance or shorten the life of the component or electrical system when operating within the design operating profile. No vehicle component generates, or is affected by, electromagnetic interference or radio-frequency interference (EMI/RFI) that can disturb the performance of electrical/electronic equipment as defined in SAE J1113 and UNECE Council Directive 95/54 (R10). TS 40.1 Hardware Mounting The mounting of the hardware is not used to provide the sole source ground, and all hardware is isolated from potential EMI/RFI, as referenced in SAE J1113. All electrical/electronic hardware mounted in the interior of the vehicle is inaccessible to passengers and hidden from view unless intended to be viewed. The hardware is mounted in such a manner as to protect it from splash or spray. All electrical/electronic hardware mounted on the exterior of the vehicle that is not designed to be installed in an exposed environment is mounted in a sealed enclosure. All electrical/electronic hardware and its mounting complies with the shock and vibration requirements of SAE J1455. TS 41. General Electrical Requirements TS 41.1 Batteries TS 41.1.1 Low -Voltage Batteries (24V) The 40’ Catalyst E2 includes two (2) Group 31, deep cycle, maintenance free batteries. This is suf- ficient to ensure reliable vehicle startup. These batteries can be “jumped” in the same manner as standard buses and an Anderson connector is provided for this in the event the batteries lose their charge. Low voltage battery state-of-charge warnings are displayed on the drivers screen. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 61 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information TS 41.1.2 Battery Cables The battery terminal ends and cable ends are color-coded with red for primary positive, black for negative and green for the intermediate voltage (12 volts). Positive and negative battery cables do not cross each other, are flexible and are sufficiently long to reach the batteries. The cables do not lie directly on top of the batteries. Battery cables are continuous except for the connection to the master battery switch and are bolted terminals meeting SAE Standard J1127-Type SGX. Battery cables are sized at 2/0 and are more than sufficient to “start” the bus. TS 41.1.3 JumpStart Proterra provides a red (24V) Anderson-style connector in the motor compartment (ProDrive), equipped with dust cap and adequately protected from moisture, dirt and debris. Alternate connect- ors are available as an option. TS 41.1.4 Battery Compartment The battery compartment prevents accumulation of snow, ice and debris on the top of the batteries and is vented and self-draining. It is only accessible from the outside of the vehicle. All compo- nents within the battery compartment, and the compartment itself, is protected from damage or cor- rosion from the electrolyte. The inside surface of the battery compartment’s access door is electri- cally insulated. The battery compartment temperature does not exceed manufacturer’s specifica- tion. The vehicle is equipped with a 12VDC and 24VDC quick disconnect switch. The battery quick dis- connect access door is identified with a decal. The battery hold-down bracket is constructed of nonconductive and corrosion-resistant material. The access door is designed to require a square key lock. The access doors are flush-fitting and incorporate a spring tensioner to retain the door in a closed position when not in use. The batteries are securely mounted on a powder-coated steel tray which accommodates the size and weight of the batteries. The battery tray pulls out easily and properly supports the batteries while they are being serviced. A locking device retains the battery tray in the stowed position. No sparking devices are located within the battery box. TS 41.1.5 Auxiliary Electronic Power Supply The standard vehicle does not utilize any gel-packs or sealed non-vented batteries for auxiliary power. If gel-packs or sealed non-vented batteries are installed, Proterra will comply with this para- graph and install them in a labeled, vented compartment accessible only to maintenance personnel. TS 41.1.6 Master Battery Switch The location of the master battery switch is clearly identified on the exterior access panel, is acces- sible in less than 10 seconds. The installation prevents corrosion from fumes and battery acid when the batteries are washed off or in normal service. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 62 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information Turning the master switch off with the power plant operating, during an emergency, shuts off the motor and does not damage any component of the electrical system. The master switch is capable of carrying and interrupting the total circuit load. The standard configuration is equipped with a single switch for disconnecting 12V and 24V power. The access panel is locked with a standard square key. TS 41.1.7 Low -Voltage Generation and Distribution The low-voltage generating system maintains the charge on fully charged batteries. The low-voltage batteries are maintained through a DC/DC converter by the high-voltage batteries. There is no gen- erator. Voltage monitoring and over-voltage output protection is provided. Dedicated power and ground are provided as specified by the component or system manufacturer. Cabling to the equipment is sized to supply the current requirements of heavy-duty systems with no greater than a 5 percent voltage drop across the length of the cable. TS 41.1.8 Circuit Protection All branch circuits are protected by current-limiting devices such as circuit breakers, fuses or solid state devices sized to the requirements of the circuit. The circuit breakers or fuses are easily acces- sible for authorized personnel. Fuse holders are constructed to be rugged and waterproof. All in-line fuses are shown in the final schematic drawings. Manually resettable circuit breakers provide a vis- ible indication of open circuits. Circuit breakers or fuses are sized to a minimum of 15 percent larger than the total circuit load. The current rating for the wire used for each circuit exceeds the size of the circuit protection being used. TS 41.2 Grounds The batteries are grounded to the chassis in a single location, as close to the batteries as possible. Ground bars are provided throughout the bus, evenly distributed to prevent ground loops. No more than five ground ring/spade terminal connections are made per ground stud with spacing between studs ensuring conductivity and serviceability. Electronic equipment and systems requiring an iso- lated ground to the battery is not grounded through the chassis. TS 41.3 Low Voltage/Low Current Wiring and Terminals Power and ground wiring conforms to specification requirements of SAE Recommended Practice J1127, J1128 and J1292 for type GXL and SXL wiring. Double insulation is maintained as close to the junction box, electrical compartment or terminals as possible. Wiring is grouped, labeled and color-coded. Wiring harnesses do not contain wires of different volt- age classes unless all wires within the harness are insulated for the highest voltage present in the DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 63 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information harness. Kinking, grounding at multiple points, stretching, and exceeding minimum bend radius are prevented. Strain-relief fittings are provided at all points where wiring enters electrical compartments. Grom- mets or other protective material is installed at points where wiring penetrates metal structures out- side of electrical enclosures. Wiring supports are protective and non-conductive at areas of wire contact and will not be damaged by heat, water, solvents or chafing. To the extent practicable, wiring is not located in environmentally exposed locations under the vehi- cle. Wiring and electrical equipment necessarily located under the vehicle is insulated from water, heat, corrosion and mechanical damage. Where feasible, front-to-rear electrical harnesses are in- stalled above the window line of the vehicle. All wiring harnesses over 5 ft. long and containing at least five wires include 10 percent (minimum one wire) excess wires for spares. Wiring harness length allow end terminals to be replaced twice without pulling, stretching or replacing the wire. Terminals are crimped to the wiring according to the connector or manufacturer’s recommendations for techniques and tools. Cable connectors are locking type, keyed and sealed, unless enclosed in watertight cabinets or the vehicle interior. Pins are removable, crimp contact type, of the correct size and rating for the wire being terminated. Unused pin positions are sealed with sealing plugs. Adjacent connectors use dif- ferent inserts or different insert orientations to prevent incorrect connections. Terminals are crimped, corrosion-resistant and full ring type or interlocking lugs with insulating fer- rules. When using pressure type screw terminal strips, only stranded wire is used. Insulation clear- ance ensures that wires have a minimum of “visible clearance” and a maximum of two ties the con- ductor diameter or 1/16 in., whichever is less. When using shielded or coaxial cable, upon stripping of the insulated, the metallic braid is free from frayed strands. Ultra-sonic and T-splices may be used with 8 awg or smaller wire. When T-splice is used, it meets these additional requirements: • It includes a mechanical clamp. • The wire supports no mechanical load in the area of the splice. • The wire is supported to prevent flexing. All splicing is staggered in the harness. Wiring located in the motor compartment (Pro Drive) is routed away from high-heat sources or is shielded and/or insulated from temperatures exceeding the wiring and connector operating requirements. The instrument panel and wiring are accessible for service from the driver’s seat or top of the panel. The instrument panel is separately removable and replaceable without damaging the instrument DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 64 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information panel or gauges. Wiring is of sufficient length and routed to permit service without stretching or chafing the wires. As standard we use HellermanTyton heavy-duty cable management system (which includes plastic tie wraps) which is the standard mechanism for securing wires in our vehicle. TS 41.4 Electrical Components All electrical components, including switches, relays, flashers and circuit breakers, are heavy-duty designs with either a successful history of application in heavy-duty vehicles or design specifica- tions for an equivalent environment. All electric motors are heavy-duty brushless type where practical, and have a continuous duty rating of no less than 40,000 hours, except washer pumps and wiper motors. All electric motors are easily accessible for servicing. TS 41.5 Electrical Compartments Relays, controllers, flashers, circuit breakers and other electrical components are mounted in easily accessible electrical compartments. Compartments exposed to the outside environment are corro- sion-resistant and sealed. The components and their functions in each electrical compartment are identified and their location recorded on a schematic drawing permanently attached to the inside of the access panel or door. The drawing is protected from oil, grease, fuel and abrasion. The front compartment is completely serviceable from the driver’s seat. “Rear start and run” controls are not required as the electric drive motor does not idle like a diesel or CNG engine. Alternatively, a “run disable” switch is located in the motor compartment (Pro- Drive). It will disable the drive system and gear selection without requiring the vehicle to be turned off. The switch is protected and rated for the environment it is installed in. Also, 12/24V disable switch and High Voltage Disconnect is also available in the motor compartment. Both of these switches can be locked in the off position with a lockout-tagout system. The bus has two diagnostic ports in the front and rear interior and a diagnostic tool for accessing vehicle information which can communicate wirelessly or via bluetooth. TS 42. General Electronic Requirements If an electronic component has an internal real-time clock, it will provide its own battery backup to monitor time when battery power is disconnected, and/or it may be updated by a network compo- nent. If an electronic component has an hour meter, it will record accumulated service time without relying on battery backup. Proterra will ensure that their electronic equipment is self -protecting in the event of shorts in the ca- bling, and also in over-voltage and reverse polarity conditions. If an electronic component is re- DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 65 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information quired to interface with other components, it will not require external pull-up and/or pull-down resis- tors. Where this is not possible, the use of pull-up or pull-down resistor is limited as much as possi- ble and is easily accessible and labeled. TS 42.1 Wiring and Terminals Kinking, grounding at multiple points, stretching and reducing the bend radius below the manufac- turer’s recommended minimum is not permitted except at our overhead charge cable installation which does result in certain areas where the bend radius is below the minimum recommended ra- dius. However, these cables have been tested by the manufacturer and Proterra expects the design as installed to last the life of the vehicle. The Proterra Catalyst vehicles have protective coverings over the high voltage wiring from the bat- tery packs and for wiring to the ProDrive area where the traction motor, transmission, and air sys- tem are located. TS 42.1.1 Discrete I/O (Inputs/Outputs) Wiring to I/O devices, either at the harness level or individual wire level, are labeled, stamped or color-coded in a fashion that allows unique identification at a spacing not exceeding 4 in. Wiring for each I/O device is bundled together. Where I/O terminals are the same voltages, jumpers may be used to connect the common nodes of each I/O terminal. TS 42.1.2 Shielding Wiring that requires shielding meets the following minimum requirements. A shield will be generated by connecting to a ground, which is sourced from a power distribution bus bar or chassis. To extent possible the shield will be connected to one side only. However, some shields are grounded at both ends per the component manufactures installation instructions (i.e. power cables between the motor and Inverter). When using shielded or coaxial cable, upon stripping of the insulation, the metallic braid is free from frayed strands, which can penetrate the insulation of the inner wires. To prevent the introduction of noise, the shield will not be connected to the common side of a logic circuit. TS 42.1.3 Communications The data network cabling is installed according to the selected protocol requirements. The physical layer of all network communication systems is not used for any purpose other than communication between the system components, unless provided for in the network specifications. Communications networks that use power line carriers (e.g., data modulated on a 24V power line) meet the most stringent applicable wiring and terminal specifications. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 66 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information TS 42.1.4 Radio Frequency (RF) Coaxial cable is used to carry the signal for all RF components such as radios, video devices, cam- eras, global positioning systems, etc. Connectors are minimized, since each connector and crimp has a loss that will attribute to attenuation of the signal. Cabling allows for the removal of antennas or attached electronics without removing the installed cable between them. The corresponding com- ponent vendors will be consulted for proper application of equipment, including installation of ca- bles. TS 42.1.5 Audio Cabling used for microphone level and line level signals is 22 AWG minimum with shielded twisted pair. Cabling used for amplifier level signals is 18 AWG minimum. TS 43. Multiplexing TS 43.1 General The primary purpose of the multiplexing system is control of components necessary to operate the vehicle. This is accomplished by processing information from input devices and controlling output devices through the use of an internal logic program. Versatility and future expansion is provided for by an expandable system architecture. The multiplex system is capable of accepting new inputs and outputs through the addition of new modules and/or the utilization of existing spare inputs and outputs. All like components in the multiplex system are modular and interchangeable with self-diagnostic capabilities. The modules are easily accessible for troubleshooting electrical failures and performing system maintenance. Multiplex input/output modules use solid-state devices to provide extended service life and individual circuit protection. Ten percent of the total number of inputs and outputs, or at least one each for each voltage type utilized (12V, 24V) at each module location is designated as spares. The Multiplex system has a number of different outputs that are individually rated to 1A, 3A, 5A or 10A max. The CAN wiring is SAE J1939 approved. Module power is GXL wiring which is SAE 1128 approved. TS 43.2 System Configuration Proterra’s 40’ Catalyst™ E2 multiplexing is centralized. The system consist of several modules connected to form a control network. It utilizes a Continental VDO multiplex system. This system is managed by a master vehicle controller, ZR-32A. It provides the configurability and the control required to integrate all systems on the bus. TS 43.2.1 I/O Signals The input/output for the multiplex system contains three types of electrical signals: discrete, modulating and analog. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 67 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information Discrete signals reflect the on/off status of switches, levers, limit switches, lights, etc. Analog signals reflect numerical data as represented by a voltage signal (for example 0–5V) or resistance signal (for example NTC thermistor). Both types of analog signals represent the status of variable devices such as rheostats, op-amps, potentiometers, temperature probes, etc. TS 44. Data Communications TS 44.1 General All data communication networks are in accordance with a nationally recognized interface standard, such as those published by SAE, IEEE or ISO. Any electronic vehicle components used on a network are conformance tested to the corresponding network standard. The vehicle is designed with a fully integrated diagnostic system were the master vehicle controller, ZR-32A, monitors and records the fault status from all systems on the main PCAN network as well as fault status from the multiplex devices. This includes subsystems such as the powertrain controller, cooling system, ABS system, HVAC system, battery management system and other power devices. This diagnostic system also includes the detection of loss of communication of all individual devises on the PCAN and MCAN network. All faults are recorded, time stamped, odometer stamped and assigned a priority level based on the severity of the fault. These priority levels are broken into 10 groups ranging from the most severe fault requiring an immediate vehicle shutdown to the least severe fault requiring attention at the next service interval. Some minor faults are only recorded to help the technician troubleshoot issues and are not indicated to the driver. Various indicators communicate to the driver the severity and priority of the fault. These indicators include a general red or amber LED tell-tale, fault specific LED tell- tales, fault specific driver’s screen displayed tell-tales and/or an audible buzzer. Many faults have the ability to automatically reset if a fault is no longer active. All faults that are active or previously active are accessed using the Proterra service tool or the maintenance menus accessi- ble from the driver’s instrument cluster. The Proterra service tool has a troubleshooting guide to aid in quick resolution of individual faults. The following inform ation is displayed when using the instru- ment cluster and Proterra service tool: • Fault status (active or previously recorded and inactive) • Identifying number (SPN and FMI according to J1939) • General description of part faulted (SPN description) • Type of fault (FMI description; i.e. value to high, to low, data erratic, loss of communication) • Mux input or output pin where fault was detected or system where fault was originated • Time, date and odometer reading at time of fault A vehicle data logger is provided to monitor J1939 communications System. It provides: • Continuous monitoring and recording of the PCAN J1939 data bus. • Software that can generate structured reports using the gathered data. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 68 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information • Software to create tools for incident definition, data import/export, analysis and presentation. • Software for recording of user selected J1939 fault codes. TS 44.2 Drivetrain Level Drivetrain components, consisting of the drive motor inverters, regenerative braking system, anti- lock braking system and all other related components, are integrated and communicate fully with respect to vehicle operation with data using SAE Recommended Communications Protocols J1939. Drivetrain components are powered by a supply voltage to ensure data communication among components exists when the vehicle ignition is switched to the “on” position. TS 44.2.1 Diagnostics, Fault Detection and Data Access Drive train performance, maintenance and diagnostic data, and other electronic messages are formatted and transmitted on the communication network. The drivetrain level has the ability to record abnormal events in memory and provide diagnostic codes and other information to service personnel. These codes can be read from the driver’s digital display or the Proterra service tool. The communication ports are located at the front and rear interior of the vehicle. TS 44.2.2 Programmability (Software) The drivetrain level components are programmable by the Agency with limitations as specified by the subsystem Supplier. The Proterra powertrain controller is programmable using the Proterra service tool laptop via the vehicle OBD port located in the rear of the vehicle. Reprogramming these controllers is access controlled via multiple user levels with different passwords. Revision control tracking is electronic and communicated on the J1939 PCAN bus. TS 44.3 Multiplex Level TS 44.3.1 Data Access Information is available via a communication port at the front and rear of the vehicle. The location of the communication ports are easily accessible. The preferred way to review this information is via the instrument cluster’s digital display. Maintenance screens, available only to technicians, provide visual feedback of each individual MUX input and output state (i.e. on, off, or faulted). Standard bus uses J1708 interface with the Asynchronous Transfer Mode Switching (ATMS) wireless communications system for transmittal of diagnostic fault codes. (Other interfaces such as J1939 are not available on the bus) TS 44.3.2 Diagnostics and Fault Detection The multiplex system has a proven method of determining its status (system health and input/output status) and detecting either active (online) or inactive (offline) faults through the use of on-board visual/audible indicators. In addition to the indicators, the system employs an advanced diagnostic and fault detection system, which is accessible via the Proterra service tool laptop. The service tool has the ability to check logic function. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 69 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information As an option, a mock-up board can be provided. TS 44.3.3 Programmability (Software) The vehicle master controller is programmable using the Proterra service tool laptop via the vehicle OBD port located in the front of the vehicle. Reprogramming these controllers is access controlled via multiple user levels with different passwords. Revision control tracking is electronic and communicated on the J1939 PCAN bus as well as displayed on the driver’s display screen. Programming of the multiplex devices is an automatic process that is completed by the vehicle ZR- 32A master controller upon startup. TS 44.4 Electronic Noise Control Third party testing per CISPR 12, 36 and ISO 11451 has been conducted to ensure that electrical and electronic subsystems and components on all buses do not emit electromagnetic radiation that will interfere with on-board systems, components or equipment, telephone service, radio or TV reception, or violate regulations of the Federal Communications Commission. Electrical and electronic subsystems on the coaches are not affected by external sources of RFI/EMI. This includes, but is not limited to, radio and TV transmission, portable electronic devices including computers in the vicinity of or onboard the buses, AC or DC power lines and RFI/EMI emissions from other vehicles. DRIVER PROVISIONS, CONTROLS AND INSTRUMENTATION TS 45. Driver’s Area Controls TS 45.1 General In general, when designing the driver’s area, SAE J833, “Human Physical Dimensions,” was used. Switches and controls are divided into basic groups and assigned to specific areas, in conformance with SAE Recommended Practice J680, Revised 1988, “Location and Operation of Instruments and Controls in Motor Truck Cabs,” and are essentially within the hand reach envelope described in SAE Recommended Practice J287, “Driver Hand Control Reach.” TS 45.2 Glare The driver’s work area is designed to minimize glare to the greatest extent possible. Objects within and adjacent to this area are matte black or dark gray in color wherever possible to reduce the reflection of light onto the windshield. The use of polished metal and light-colored surfaces within and adjacent to the driver’s area was avoided. TS 45.3 Visors/Sun Shades An adjustable roller type sunscreen is provided over the driver’s windshield. The sunscreen is capable of being lowered to the midpoint of the driver’s window. When deployed, the screen is secure, stable, and will not rattle, sway or intrude into the driver’s field of view due to the motion of the coach or as a result of air movement. Once lowered, the screen remains in the lowered position until returned to the stowed position by the driver. Sunscreen is shaped to minimize light leakage between the visor and windshield pillars to the extent possible. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 70 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information An option to include an additional driver’s side window sunscreen is also available. TS 45.4 Driver’s Controls Frequently used controls are in easily accessible locations. These include the door control, kneel control, windshield wiper/washer controls, ramp, and lift and run switch. Any switches and controls necessary for the safe operation of the bus are conveniently located and provide ease of operation. They are identifiable by shape, touch and permanent markings. Controls also are located so that passengers may not easily tamper with control settings. All panel-mounted switches and controls are marked with easily read identifiers. Graphic symbols conform to SAE Recommended Practice J2402, “Road Vehicles – Symbols For Controls, Indicators, and Tell Tales,” where available and applicable. Color of switches and controls are dark with contrasting typography or symbols. Mechanical switches and controls are replaceable, and the wiring at these controls are serviceable from a convenient location. Switches, controls and instruments are dust- and water-resistant. All switches/controls in the driver’s controls area, if required, can be mounted in an angled panel steep enough to discourage drivers from using it as a personal storage area for items like food, drinks, cell phones, etc. TS 45.5 Normal Bus Operation Instrumentation and Controls The following list identifies bus controls used to operate the bus. These controls are either frequently used or critical to the operation of the bus. They are located within easy reach of the operator. The operator will not be required to stand or turn to view or actuate these controls unless specified otherwise. Systems or components monitored by onboard diagnostics system are displayed in clear view of the operator and provide visual and/or audible indicators. The intensity of indicators permits easy determination of on/off status in bright sunlight but not cause a distraction or visibility problem at night. All indicators are illuminated using backlighting. The indicator panel is located in the instrument cluster mounted in the center of the driver’s dash, within easy view of the operator instrument panel. All indicators have a method of momentarily testing their operation. The audible alarm is tamper-resistant and has an outlet level between 80 and 83 dBA when measured at the location of the operator’s ear. On-board displays visible to the operator are limited to indicating the status of those functions described herein that are necessary for the operation of the bus. All other indicators needed for diagnostics and their related interface hardware is concealed and protected from unauthorized access. Table 6 represents Proterra’s standard instruments and alarms.

Exterior panels are sufficiently stiff to minimize vibration, drumming or flexing while the bus is in service. When panels are lapped, the upper and forward panels will act as a watershed. The windows, hatches and doors are able to be sealed. Accumulation of spray and splash generated by the bus’s wheels is minimized on windows and mirrors. TS 62.1 Materials Body materials were selected and the body fabricated to reduce maintenance, extend durability and provide consistency of appearance throughout the service life of the bus. Detailing was kept simple, and add-on devices and trim are minimized and integrated into the basic design. The use of composite materials provides a much stronger, more durable and longer lasting body than provided with conventional steel or aluminum “stick built” construction. Finite Element Analysis indicates the body should easily endure sixteen years of transit service. TS 62.2 Roof-Mounted Equipment A non-skid, clearly marked walkway or steps was incorporated on the roof to provide access to equipment without damaging any system or bus paneling. TS 63. Pedestrian Safety Exterior protrusions along the side and front of the bus greater than ½ in. and within 80 in. of the ground have a radius no less than the amount of the protrusion. The exterior rearview mirrors, cameras and required lights and reflectors are exempt from the protrusion requirement. Advertising frames protrude no more than ⅞ in. from the body surface. Grilles, doors, bumpers and other features on the sides and rear of the bus are designed to minimize toeholds or handholds. Exterior protrusions do not cause a line-of -sight blockage for the driver. TS 64. Repair and Replacement TS 64.1 Side Body Panels The 40’ Catalyst E2 has an all-composite body. Composite body buses do not have exterior paneling. The outer skin is integral to the body structure. When damage occurs to the exterior of the vehicle, the repair is contained to just the damaged area. The side body from floor to window is DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 86 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information repairable with common composite repair techniques. The body is also covered with a gel coat that resists chips and cracks. TS 64.2 Composite Body Repair Composite bus bodies are pretty resistant to impact, however sections of a monocoque composite body or other equipment that may be damaged in normal service are easily repairable with common composite repair techniques. If requested by the by the agency Proterra will send our regional ser- vice representative to review the bus after the accident. The service rep will take pictures of the is- sue and assess the damage, then will communicate with the customer and Proterra Service. There are 3 options to perform the repair: 1) For relatively minor issues that have just affected the skin layer of the bus body or an access door, our field service representatives can handle the repair or can assist the agency’s maintenance group to complete. Proterra keeps spare parts of access doors if it is the preference of the agency to have these replaced instead. 2) Proterra offers optional composite repair training to all customers. If the agency has its own body shop or a body shop of preference, it can opt to complete this training and then complete any repairs internally. Proterra will provide a recommended mate- rials list and can support with instructions as needed. 3) Proterra has partnered with a third party composite repair company who can come to the agency and complete the repair. Proterra has already completed several projects with them, although none were related to accident repairs. TS 65. Rain Gutters Rain gutters are integral to the design of the composite body. Our vehicles employ a uniquely designed roof profile that channels water away from passenger entrance and exit areas. This provides similar functionality via the body design and roof profile. TS 66. License Plate Provisions Provisions have been made to mount standard-size U.S./Canada license plates per SAE J686 on the rear of bus. These provisions direct-mount the license plates so that they can be cleaned by automatic bus-washing equipment without being caught by the brushes. The rear license plate provision is illuminated per SAE J587. An option for a front license plate is available. TS 66.1 Rub rails The standard configuration is for no rub rails installed. Our fender flares act as a rub rail and our composite body is more robust then the thin aluminum paneling of most buses. TS 67. Fender Skirts Fender skirts are installed to minimize water spray from the bus in wet conditions. They do not extend beyond the body width. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 87 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information TS 68. Wheel Covers The standard configuration is for no wheel covers. TS 68.1 Splash Aprons The standard configuration is for no splash aprons. TS 69. Service Compartments and Access Doors TS 69.1 Access Doors Conventional or pantograph hinged doors are used for the motor compartment and for all auxiliary equipment compartments. Access openings are sized for easy performance of tasks within the compartment, including tool operating space. Access doors are of rugged construction and maintain mechanical integrity and function under normal operations throughout the service life of the bus. They close flush with the body surface. All doors are hinged at the top or on the forward edge and are prevented from coming loose or opening during transit service or in bus washing operations. All access doors are retained in the open position by gas-filled springs with safety props and are easily operable by one person. Springs and hinges are corrosion resistant. Latch handles are flush with, or recessed behind, the body contour and are sized to provide an adequate grip for opening. The lower side access doors for the motor compartment, when opened, will restrict access to the upper side access doors. All other access doors, when opened, do not restrict access for servicing other components or systems. TS 69.2 Access Door Latch/Locks Access doors larger than 100 sq in. are equipped with corrosion-resistant flush-mounted latches or locks. All such access doors that require a tool to open are standardized throughout the vehicle and will require a nominal 5/16 in. square male tool to open or lock. TS 70. Bumpers TS 70.1 Location Bumpers provide impact protection for the front and rear of the bus with the top of the bumper being 27 in., ±2 in., above the ground. Bumper height is such that when one bus is parked behind another, a portion of the bumper faces will contact each other. TS 70.2 Front Bumper No part of the bus, including the bumper, will be damaged as a result of a 5mph impact of the bus at curb weight with a fixed, flat barrier perpendicular to the bus’s longitudinal centerline. The bumper will return to its pre-impact shape within 10 minutes of the impact. The bumper protects the bus from damage as a result of 6.5 mph impacts at any point by the common carriage with contoured impact surface defined in Figure 2 of FMVSS 301 loaded to 4000lbs parallel to the longitudinal centerline of the bus. It protects the bus from damage as a result of 5.5mph impacts into the corners at a 30° angle to the longitudinal centerline of the bus. The energy absorption system of the bumper is independent of every power system of the bus and will not require service DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 88 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information or maintenance in normal operation during the service life of the bus.

TS 70.3 Rear Bumper No part of the bus, including the bumper, will be damaged as a result of a 2mph impact with a fixed, flat barrier perpendicular to the longitudinal centerline of the bus. The bumper will return to its pre- impact shape within 10 minutes of the impact. When using a yard tug with a smooth, flat plate bumper 2 ft wide contacting the horizontal centerline of the rear bumper, the bumper provides protection at speeds up to 5 mph, over pavement discontinuities up to 1 in. high, and at accelerations up to 2 mph/sec. The rear bumper protects the bus when impacted anywhere along its width by the common carriage with contoured impact surface defined in Figure 2 of FMVSS 301 loaded to 4000 lbs, at 4 mph parallel to or up to a 30° angle to the longitudinal centerline of the bus. The rear bumper is shaped to preclude unauthorized riders standing on the bumper. The bumper will not require service or maintenance in normal operation during the service life of the bus. The bumper may increase the overall bus length specified by no more than 7 in. The bumpers are a three piece design. TS 70.4 Bumper Material Bumper material is corrosion-resistant and will withstand repeated impacts of the specified loads without sustaining damage. Bumpers are made of aluminum and the outer shell is solid elastomer. These bumper qualities will be sustained throughout the service life of the bus. TS 71. Finish and Color TS 71.1 Appearance All exterior surfaces are smooth and free of wrinkles and dents. The 40’ Catalyst E2 is a composite body. It has a gel-coated exterior finish in white with Proterra logos on the front & rear. Options for paint or full-body decal / wrap are available. TS 72.

The service area lamps are suitable for the environment in which they are mounted. Motor compartment lamps are controlled by a switch mounted in the motor compartment. All other service area lamps are controlled by switches mounted on or convenient to the lamp assemblies. Power to the service area lighting is programmable. Power latches on with activation of the switch and is automatically discontinued (timed out) after 30 minutes to prevent damage caused by inadvertently leaving the service area lighting switch in the “on” position after repairs are made. INTERIOR PANELS AND FINISHES TS 74. General Requirements Materials were selected on the basis of maintenance, durability, appearance, safety, flammability and tactile qualities. Materials are strong enough to resist everyday abuse and be vandalism and corrosion resistant. Trim and attachment details are kept simple and unobtrusive. Interior trim is secured to avoid resonant vibrations under normal operational conditions. Interior surfaces more than 10 in. below the lower edge of the side windows or windshield are shaped so that objects placed on them fall to the floor when the coach is parked on a level surface. Any components and other electrical components within close proximity to these surfaces are also resistant to this cleaning method. The standard configuration does not have any additional anti-graffiti/vandalism surface treatments. TS 75. Interior Panels Panels are easily replaceable and tamper resistant. They are reinforced, as necessary, to resist vandalism and other rigors of transit bus service. Individual trim panels and parts are interchangeable to the extent practicable. Interior panels meet FMVSS 302. An option is available to install alternate interior panels that meet FTA Docket 90-A. TS 75.1 Driver Area Barrier A barrier or bulkhead between the driver and the street-side front passenger seat is provided. The barrier minimizes glare and reflections in the windshield directly in front of the barrier from interior lighting during night operation. Location and shape permits full seat travel and reclining possibilities that can accommodate the shoulders of a 95th-percentile male. The partition has a side return and stanchion to prevent passengers from reaching the driver by standing behind the driver’s seat. The lower area between the seat and panel is accessible to the driver. The partition is strong enough in conjunction with the entire partition assembly for mounting of such equipment as flare kits, fire extinguishers (1.2kg), microcomputer, public address amplifier, etc. The panel is properly attached to minimize noise and rattles. The driver’s barrier extends continually from the floor area to the ceiling and from the bus wall to the first stanchion immediately behind the driver to provide security to the driver and to limit passenger conversation. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 91 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information Options for full or partial driver barriers that provide a barrier between entering passengers are available. TS 75.2 Modesty Panels Sturdy divider panels constructed of durable, unpainted, corrosion-resistant material complementing the interior are provided to act as both a physical and visual barrier for seated passengers. Design and installation of modesty panels located in front of forward-facing seats include a handhold or grab handle along its top edge. These dividers are mounted on the sidewall and project toward the aisle no farther than passenger knee projection in longitudinal seats or the aisle side of the transverse seats. Modesty panels extend from at least the window opening of the side windows, and those forward of transverse seats extend downward to 1 and 1½ in. above the floor. Panels forward of longitudinal seats extend to below the level of the seat cushion. Dividers positioned at the doorways, where applicable, provide no less than a 2½ in. clearance between the modesty panel and a fully open, inward opening door, or the path of a deploying flip-out ramp to protect passengers from being pinched. Modesty panels installed at doorways are equipped with grab rails if passenger assists are not provided by other means. The modesty panel and its mounting withstand a static force of 250 lbs applied to a 4 × 4 in. area in the center of the panel without permanent visible deformation. TS 75.3 Front End The entire front end of the bus is sealed to prevent debris accumulation behind the dash and to prevent the driver’s feet from kicking or fouling wiring and other equipment. The front end is free of protrusions that are hazardous to passengers standing at the front of the standee line area of the bus during rapid decelerations. Paneling across the front of the bus and any trim around the driver’s compartment is formed metal or thermo-formed plastic material. Composite dash panels are reinforced as necessary, vandal-resistant and replaceable. All colored, painted and plated parts forward of the driver’s barrier are finished with a surface that reduces glare. Any mounted equipment has provision to support the weight of equipment. TS 75.4 Rear Bulkhead Proterra’s standard seating for the 40’ Catalyst E2 bulkhead does not provide access to the motor compartment area (ProDrive). Any equipment installed at the rear of the bus can be accessed by the removal of fastened panels. The rear bulkhead and rear interior surfaces are material suitable for exterior skin; painted and finished to exterior quality. The rear bulkhead paneling is contoured to fit the ceiling, side walls and seat backs so that any litter or trash will tend to fall to the floor or seating surface when the bus is on a level surface. Any air vents in this area are louvered to reduce airflow noise and to reduce the probability of trash or liter being thrown or drawn through the grille. Additionally, the rear bulkhead area is predominately taken up by the rear window. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 92 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information TS 75.5 Headlining Ceiling panels are made of durable, corrosion resistant, easily cleanable material. Headlining is supported to prevent buckling, drumming or flexing and is secured without loose edges. Headlining materials are treated or insulated to prevent marks due to condensation where panels are in contact with metal members. Moldings and trim strips, as required to make the edges tamperproof, are stainless steel, aluminum or plastic, colored to complement the ceiling material. Headlining panels covering operational equipment that is mounted above the ceiling is on hinges for ease of service but retained to prevent inadvertent opening. TS 75.6 Fastening Interior panels are attached so that there are no exposed unfinished or rough edges or rough surfaces. Fasteners are corrosion resistant. Panels and fasteners are not easily removable by passengers. Exposed interior fasteners are minimized, and where required are tamper resistant. TS 75.7 Insulation The Proterra Catalyst insulation meets the requirement of FMVSS 302. It has a composite body that provides even better insulation performance than adding insulation to a metal body bus. Composite body offers better U-factor / insulating properties. Insulation properties are unimpaired during the service life of the bus. Any insulation material used inside the motor compartment will not absorb or retain oils or water and are designed to prevent casual damage that may occur during maintenance operations. The bus body is thoroughly sealed so that the driver or passengers cannot feel drafts during normal operations with the passenger doors closed. TS 75.8 Floor Covering The floor covering has a non-skid walking surface that remains effective in all weather conditions. The floor covering, as well as transitions of flooring material to the main floor and to the entrance and exit area, is smooth and present no tripping hazards. Seams are sealed/welded per manufacturer’s specifications. The standee line is approximately 2 in. wide and extends across the bus aisle. The color and pattern is consistent throughout the floor covering. Any areas on the floor that are not intended for standees, such as areas “swept” during passenger door operation, are clearly and permanently marked. The floor is easily cleaned and arranged to minimize debris accumulation. A one-piece center strip extends from the vertical wall of the rear settee between the aisle sides of transverse seats to the standee line. The floor is of a bi-level construction and the center strip is one piece at each level. The covering between the center strip and the wheel housings may be separate pieces. At the rear door, a separate strip as wide as the door extends from the center strip to the outboard edge of the rear/exit area. The floor under the seats is covered with smooth surface flooring material. The floor covering shall closely fit the sidewall in a fully sealed butt joint or extend to the top of the cove. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 93 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information TS 75.9 Interior Lighting The light source is located to minimize windshield glare, with distribution of the light focused primarily on the passengers’ reading plane while casting sufficient light onto the advertising display. The lighting system is designed to form part of or the entire air distribution duct. The lens material is translucent polycarbonate. Lenses are designed to effectively “mask” the light source. Lenses are sealed to inhibit incursion of dust and insects yet be easily removable for service. Access panels are provided to allow servicing of components located behind light panels. The entire light fixture is hinged. TS 75.10 Passenger The driver can select either dim, off or bright for interior lighting. When in “day run” mode, all interior lights will be as selected by the driver. In “night run” mode, the front most lights on each side (behind the driver and the front door) are turned on only when either door is opened. With both doors closed, the front most lights will be off to minimize light reflection and glare on the windshield. The rear lights will be on in the setting selected by the driver (off, dim or bright). Optionally, all of the lights can be configured to turn on to the dim or bright position when either door is opened. All interior lighting is turned off whenever the transmission selector is in reverse. The interior lights are LED. TS 75.11 Driver’s Area The driver’s area has a light to provide general illumination, and it illuminates the half of the steering wheel nearest the driver to a level of 5 to 10 foot-candles. TS 75.12 Seating Areas Seating lights were optimized to reduce glare on the driver’s area. With the front door closed and cabin lighting on (full and half, bright and dim) the light provided on a 1 sq. ft. plane at an angle of 45 degrees from horizontal, centered 33 in. above the floor and 24 in. in front of the seat back at each seat position. Average light level for the rear bench seats is above 7 foot-candles. TS 75.13 Vestibules/Doors Floor surface in the aisles is a minimum of 10 foot-candles, and the vestibule area a minimum of 4 foot-candles with the front doors open and a minimum of 2 foot-candles with the front doors closed. The front entrance area and curb lights illuminate when the front door is open. Rear exit area and curb lights illuminate when the rear door is opened. Proterra and our customers have evaluated the light levels and found this to be the optimum design for passenger safety and reduced glare. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 94 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information TS 75.14 Step Lighting Step lighting for the intermediate steps between lower and upper floor levels is a minimum of 4 foot- candles and illuminates at all times in “night run” position and when doors are open in “day run” position. The step lighting is low profile to minimize tripping and snagging hazards for passengers and is shielded as necessary to protect passengers’ eyes from glare. TS 75.15 Ramp Lighting Exterior and interior ramp lighting comply with federal regulations. TS 75.16 Farebox Lighting A light fixture is mounted in the ceiling above the farebox location. The fixture is capable of projecting a concentrated beam of light on the farebox. This light will automatically come on whenever the front doors are opened and the run switch is in the “night run” position. Additionally the driver can command the fare box lighting on when the front door is open with a switch in the driver’s workplace. TS 76. Fare Collection Space and structural provisions are made for installation of currently available fare collection devices, which is as far forward as practicable. Location of the fare collection device does not restrict traffic in the vestibule, including wheelchairs if a front door loading device is used, and allows the driver to easily reach the farebox controls and to view the fare register. The farebox does not restrict access to the driver’s area, does not restrict operation of driver’s controls and does not—either by itself or in combination with stanchions, transfer mounting, cutting and punching equipment, or route destination signs—restrict the driver’s field of view per SAE Recommended Practice J1050. The location and mounting of the fare collection device allows use, without restriction, by passengers. The farebox location permits accessibility to the vault for easy manual removal or attachment of suction devices. Meters and counters on the farebox are readable on a daily basis. The floor under the farebox is reinforced as necessary to provide a sturdy mounting platform and to prevent shaking of the farebox. Transfer mounting, cutting and punching equipment will be located in a position convenient to the driver. TS 77. Interior Access Panels and Doors Access for maintenance and replacement of equipment is provided by panels and doors that appear to be an integral part of the interior. Access doors are hinged with gas props or over-center springs, where practical, to hold the doors out of the mechanic’s way. Panels prevent entry of mechanism lubricant into the bus interior. Some access doors are secured with hand screws or latches. All fasteners that retain access panels are, whenever practical, captive in the cover. Other access doors are secured with locks. The locks are standardized so that only one tool is required to open access doors on the bus.

TS 78.6 Hip-to-Knee Room Hip-to-knee room measured from the center of the seating position, from the front of one seat back horizontally across the highest part of the seat to a vertical surface immediately in front, is a minimum of 26 in. At all seating positions in paired transverse seats immediately behind other seating positions, hip-to-knee room is no less than 27 in. TS 78.7 Foot Room Foot room, measured at the floor forward from a point vertically below the front of the seat cushion, is no less than 14 in. Seats immediately behind the wheel housings and modesty panels may have foot room reduced. TS 78.8 Aisles The aisle between the seats is no less than 20 in. wide at seated passenger hip height. Seat backs are shaped to increase this dimension to no less than 24 in. at 32 in. above the floor (standing passenger hip height). TS 78.9 Dimensions DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 97 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information Figure 18- Seating Dimensions and Standard Configuration Proterra complies with this paragraph. Seat dimensions for the various seating arrangements have the following dimensions (refer to Figure 18): • The width, W, of the two-passenger transverse seat is a minimum 35 in. • The length, L, is 17 in., ±1 in. • The seat back height, B, is a minimum of 15 in. • The seat height, H, is 17 in., ± 1 in. For the rear lounge (or settee) and longitudinal seats, and seats located above raised areas for storage of under-floor components, a cushion height of up to 18 in., ±2 in., will be allowed. • Foot room = F. • The seat cushion slope, S, is between 5 and 11 deg. • The seat back slope, C, is between 8 and 17 deg. • Hip to knee room = K. • The pitch, P, is shown as reference only. TS 78.10 Structure and Design The passenger seat frame and its supporting structure is constructed and mounted so that space under the seat is maximized and is completely free of obstructions to facilitate cleaning. Seats, structures and restraints around the securement area do not infringe into the mobility device envelope or maneuverability. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 98 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information The transverse seat structure is fully cantilevered from the sidewall with sufficient strength for the intended service. The lowest part of the seat assembly that is within 12 in. of the aisle is at least 10 in. above the floor. In locations at which cantilevered installation is precluded by design and/or structure, other seat mounting may be used. All transverse objects—including seat backs, modesty panels, and longitudinal seats—in front of forward-facing seats do not impart a compressive load in excess of 1000lbs onto the femur of passengers ranging in size from a 5th-percentile female to a 95th-percentile male during a 10g deceleration of the bus. This deceleration peaks at 0.05 to 0.015 seconds from initiation. Permanent deformation of the seat resulting from two 95th-percentile males striking the seat back during this 10g deceleration does not exceed 2 in., measured at the aisle side of the seat frame at height H. The seat back does not deflect more than 14 in., measured at the top of the seat back, in a controlled manner to minimize passenger injury. Structural failure of any part of the seat or sidewall does not introduce a laceration hazard. The seat assembly withstands static vertical forces of 500 lbs applied to the top of the seat cushion in each seating position with less than ¼ in. permanent deformation in the seat or its mountings. The seat assembly withstands static horizontal forces of 500 lbs evenly distributed along the top of the seat back with less than ¼in. permanent deformation in the seat or its mountings. The seat backs at the aisle position and at the window position withstands repeated impacts of two 40-lb sandbags without visible deterioration. The back of each transverse seat incorporates a handhold no less than ⅞ in. in diameter for standees and seat access/egress. The handhold will not be a safety hazard during severe decelerations. The handhold extends above the seat back near the aisle so that standees shall have a convenient vertical assist, no less than 4 in. long that may be grasped with the full hand. This handhold does not cause a standee using this assist to interfere with a seated 50th-percentile male passenger. The handhold is also usable by a 5th-percentile female, as well as by larger passengers, to assist with seat access/egress for either transverse seating position. The upper rear portion of the seat back and the seat back handhold immediately forward of transverse seats are padded and/or constructed of energy-absorbing materials. During a 10g deceleration of the bus, the HIC number (as defined by SAE Standard J211a) does not exceed 400 for passengers ranging in size from a 5th percentile female through a 95th percentile male. The seat back handhold may be deleted from seats that do not have another transverse seat directly behind and where a vertical assist is provided. Longitudinal seats are the same general design as transverse seats but without seat back handholds. Longitudinal seats may be mounted on the wheelhouses. Armrests are included on the ends of each set of longitudinal seats except on the forward end of a seat set that is immediately to the rear of a transverse seat, the driver’s barrier, or a modesty panel, when these fixtures perform the function of restraining passengers from sliding forward off the seat. Armrests are not required on longitudinal seats located in the wheelchair parking area that fold up when the armrest on the adjacent fixed longitudinal seat is within 3½ in. of the end of the seat cushion. Armrests are located from 7 to 9 in. above the seat cushion surface. The area between the armrest and the seat cushion DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 99 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information is closed by a barrier or panel.

Seat back handhold and armrests withstands 25,000 impacts in each direction of a horizontal force of 125 lbs. with less than ¼in. permanent deformation and without visible deterioration. TS 78.11 Construction and Materials Selected materials minimize damage from vandalism and reduce cleaning time. The seats are attached to the frame with hex bolts rather than tamper-resistant fasteners. Coloring is consistent throughout the seat material, with no visually exposed portion painted. Any exposed metal touching the sides or the floor of the bus is stainless steel. The seat, pads and cushions are contoured for individuality, lateral support and maximum comfort and fit the framework to reduce exposed edges. The minimum radius of any part of the seat back, handhold or modesty panel in the head or chest impact zone is a nominal ¼in. The seat back and seat back handhold immediately forward of transverse seats are constructed of energy-absorbing materials to provide passenger protection and, in a severe crash, to allow the passenger to deform the seating materials in the impact areas. Complete seat assemblies are interchangeable to the extent practicable. TS 79. Passenger Assists Passenger assists in the form of full grip, vertical stanchions or handholds are provided for the safety of standees and for ingress/egress. Passenger assists are convenient in location, shape and size for both the 95th-percentile male and the 5th-percentile female standee. Starting from the entrance door and moving anywhere in the bus and out the exit door, a vertical assist is provided either as the vertical portion of the seat back assist or as a separate item so that a 5th-percentile female passenger may easily move from one assist to another using one hand and the other without losing support. All handholds and stanchions at the front doorway, around the farebox, and at interior steps for bi-level designs are powder-coated in a high-contrast yellow color. The forward- most vertical stanchions on either side of the aisle immediately behind the driver’s area are a stainless steel finish. TS 79.1 Assists Excluding those mounted on the seats and doors, the assists have a cross-sectional diameter between 1¼ and 1½ in. or provide an equivalent gripping surface with no corner radii less than ¼ in. All passenger assists permit a full hand grip with no less than 1½ in. of knuckle clearance around the assist. Passenger assists are designed to minimize catching or snagging of clothes or personal items and are capable of passing the NHTSA Drawstring Test. Any joints in the assist structure is underneath supporting brackets and securely clamped to prevent passengers from moving or twisting the assists. Seat handholds may be of the same construction and finish as the seat frame. Door-mounted passenger assists are powder-coated metal. Connecting tees and angles are powder-coated metal castings. Assists will withstand a force of 300 lbs. applied over a 12in. lineal dimension in any direction normal to the assist without permanent DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 100 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information visible deformation.

TS 79.7 Wheel Housing Barriers/Assists Passenger assists are mounted around the exposed sides of the wheel housings, which are designed to prevent passengers from sitting on wheel housings. Such passenger assists also effectively retain items, such as bags and luggage, placed on top of wheel housings. TS 80. Passenger Doors Passenger doors and doorways comply with ADA requirements. The 40’ Catalyst E2 comes standard with pneumatic doors from Ventura Systems. All-electric doors are also available from Ventura Systems. Doorways are provided in the locations and styles as follows. TS 80.1 Front door The front door is forward of the front wheels and under direct observation of the driver. TS 80.2 Rear Door The curbside doorway centerline is located rearward of the point midway between the front door centerline and the rearmost seat back. The doors are pneumatic and operate per specification at air pressures between 90 and 130 psi. TS 80.3 Materials and Construction Structure of the doors, their attachments, inside and outside trim panels and any mechanism exposed to the elements are corrosion resistant. Door panel construction is of corrosion-resistant metal or reinforced non-metallic composite materials. When fully opened, the doors provide a firm support and will not be damaged if used as an assist by passengers during ingress or egress. Door edges are sealed to prevent infiltration of exterior moisture, noise, dirt and air elements from entering the passenger compartment, to the maximum extent possible based on door types. The closing edge of each door panel has no less than 2 in. of soft weather stripping. The doors, when closed, will be effectively sealed, and the hard surfaces of the doors are at least 4 in. apart (not applicable to single doors). The combined weather seal and window glazing elements of the front door do not exceed 10° of binocular obstruction of the driver’s view through the closed door. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 102 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information TS 80.4 Dimensions Figure 19-Transit Bus Minimum Door Opening When open, the front door leave an opening no less than 74.9 in. in height. The front door clear width is 33.2” with the doors fully open. The rear door leaves an opening height of 75.75” and the clear width is 38.6” with the door fully open. TS 80.5 Door Glazing The doors on the 40’ Catalyst E2 are both fitted with full length glazing. Because the glazing is full length, it is bonded to the frame to maximize vision area and for aesthetic reasons. There is really no way due to current door construction to fit the glazing into a rubber frame. The manufacturer’s recommended repair procedure for replacing damaged glazing can be provided upon request. TS 80.6 Door Projection TS 80.6.1 Exterior The exterior projection of the front doors beyond the side of the bus is minimized and does not block the line of sight of the rear exit door via the curb side mirror when the doors are fully open. The exterior projection of both doors is minimized and does not exceed 14 in. during the opening or closing cycles or when doors are fully opened TS 80.6.2 Interior Projection inside the bus does not cause an obstruction of the rear door mirror or cause a hazard for standees. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 103 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information TS 80.7 Door Height Above Pavement It is possible to open and close either passenger door when the bus loaded to gross vehicle weight rating is not knelt and parked with the tires touching an 8in. high curb on a street sloping toward the curb so that the street-side wheels are 5 in. higher than the right-side wheels. TS 80.8 Closing Force Closing door edge speed does not exceed 12 in. per second, and opening door speed does not exceed 19 in. per second. Power doors does not slam closed under any circumstance, even if the door is obstructed during the closing cycle. If a door is obstructed during the closing cycle, the pressure exerted on the obstruction does not increase once initial contact has been made. Doors closed by a return spring or counterweight-type device are equipped with an obstruction- sensing device that, at a minimum, alerts the driver if an obstruction is detected between the closing doors. Doors closed by a return spring or counterweight type device, when unlocked, are capable of being pushed to the point where the door starts to open with a force not to exceed 25 lbs applied to the center edge of the forward door panel. Whether or not the obstruction-sensing system is present or functional, it is possible to withdraw a 1½ in. diameter cylinder from between the center edges of a closed and locked door with an outward force not greater than 35 lbs. TS 80.8.1 Rear Door Closing Force Power-close rear doors are equipped with an obstruction-sensing system such that if an obstruction is within the path of the closing doors, the doors will stop and/or reverse direction. Our standard system will impart a force less than 10-lbs on a 1 sq. in. obstruction. TS 80.9 Actuators Doors open or close completely in not more than 3.5 seconds from the time of control actuation and are subject to the closing force requirements. Door actuators are adjustable so that the door opening and closing speeds can be independently adjustable to satisfy the above requirements. Actuators and the complex door mechanism are concealed from passengers but are easily accessible for servicing. The door actuators are rebuildable. The standard doors are powered by compressed air. The exhaust from the door system is not routed below the floor of the bus. It exits through a muffler on the valve block of the actuator mechanism. The majority of oil in the air lines is separated out by an individual air filter for each door. Door actuators and associated linkages will maximize door holding forces in the fully open and fully closed positions to provide firm, non-rattling, non-fluttering door panels while minimizing the force exerted by the doors on an obstruction midway between the fully open and closed positions. The rear door actuator is under the complete control of the vehicle operator and will open and close in response to the driver’s control. DocuSign Envelope ID: 3559E0D8-08BE-4558-BF53-E04243E86277 Page 104 Technical Specifications – 40’ Catalyst E2, Rev 2 Proterra Confidential Information Doors that employ a “swing” or pantograph geometry and/or are closed by a return spring or counterweight-type device will be equipped with a positive mechanical holding device that automatically engages and prevents the actuation mechanism from being back-driven from the fully closed position. The holding device is overcome only when the driver’s door control is moved to an “Exit Door Enable” position and the vehicle is moving at a speed of less than 2 mph, or in the event of actuation of the emergency door release. Locked doors require a force of more than 300 lbs to open manually. When the locked doors are manually forced to open, damage is limited to the bending of minor door linkage with no resulting damage to the doors, actuators or complex mechanism. TS 80.10 Emergency Operation In the event of an emergency, it is possible to manually open doors designated as emergency exits from inside the bus using a force of no more than 25 lbs after actuating an unlocking device. The unlocking device is clearly marked as an emergency-only device and requires two distinct actions to actuate. The respective door emergency unlocking device is accessible from the doorway area. The unlocking device is easily reset by the operator without special tools or opening the door mechanism enclosure. Doors that are required to be classified as “emergency exits” meet the requirements of FMVSS 217. TS 80.11 Door Control The door control is located in the operator’s area within the hand reach envelope described in SAE Recommended Practice J287, “Driver Hand Control Reach”. The 40’ Catalyst E2 standard configuration is for two push button doors controls switches (front door and back door). The controls do not provide tactile feedback to indicate commanded door position, but resist inadvertent door actuation by providing visual feedback. An additional exterior front door switch is located on the curbside headlight bezel. This exterior door switch opens the front door and illuminates the interior of the vehicle for 1 minute. The front door remains in the commanded position even if power is removed or lost. TS 80.12 Door Controller The doors are operated by push-button controls, conveniently located and operable within the driver’s reach. The push buttons are labeled. There is a separate set of push button controls for the front and rear door. These buttons operate as follows: Push either the “front or rear door” button to open that door. While the door is opening or closing, a lamp in the button will flash on and off. When the door is fully opened, the button lamp illuminates steadily (does not flash). Push the button again to close the door. Options for a five-position door controller are also available. TS 80.13 Door Open/Close Operation of, and power to, the passenger doors is completely controlled by the operator.

Wiring Installation 60kW and 125kW PCS Charge System Installation Manual (037378_E03) Chapter 3: Wiring Installation This following section outlines the process for wiring the Proterra Power Control System (PCS) equipment. The intent of providing this information is to assist a qualified contractor to wire the new Power Control System equipment in accordance with National Electric Code (NEC) requirements. In all cases the qualified contractor is responsible for adhering to NEC requirements when wiring electrical equipment, whether or not these requirements are explicitly stated in this document. IMPORTANT! If conflicting requirements exist between this document, NEC requirements or local electrical codes, the strictest requirement should be followed. In almost all cases the qualified contractor will need to obtain a local (state and/or county) inspection of work done. The local inspectors should be considered an "authority having jurisdiction”. As an authority having jurisdiction, local inspectors can refuse to pass inspection based on their understanding of the NEC. If any unusual situations are encountered, consult with Proterra Engineering and the local inspectors before proceeding with wiring of electrical equipment. Before wiring, ensure the following requirements have been met: • Electrical input must be 480V three phase in a Five Wire Wye configuration. • Use 90°C copper wire only. • The circuit breaker at the panel must be OFF. • The PCS must be grounded to true earth. • Installer must have an insulated grounding conductor as part of the branch circuit that supplies the PCS. • The grounding conductor is to be grounded to earth at the service equipment or, when supplied by a separately derived system, at the supply transformer. • All connections must comply with all local codes and ordinances. Note: The installer SHOULD NOT add a ground rod to this system.

Wiring Installation 60kW and 125kW PCS Charge System Installation Manual (037378_E03) Terminate the Dispenser Remote Voltage Sense Wiring This procedure details how to terminate the Charging Dispenser remote voltage sense wiring. The Dispenser remote voltage sense wiring is typically routed through the 3 -inch conduit along with the high-voltage DC cables from the bottom of the PCS and entering the Dispenser enclosure through the bottom of the enclosure. The remote voltage se nse wires are terminated near the DC Cable connections. The wires are labeled with the signal name when shipped to the customer site. IMPORTANT! The Riser Diagram may show more wires than actually need to be terminated. These additional wires should still be pulled and are used as spares. 1. Route the Remote Voltage Sense wires from the PCS to the Dispenser. NOTICE! Ensure that the wires are labeled at each end to ensure proper terminations can be made. Figure 3-19.
