Part List Notes:
1. This part is not normally available from Customer Service. Approval from the Field Service
Manager is required before ordering.
2. The individual parts located on the PCBs are listed in the Electrical Part List.
3. This part is critical for safety purposes. Failure to use a substitute part with the same safety
characteristics as the recommended replacement part might create shock, fire and/or other
hazards.
Note: If you are replacing the PCB Assembly (item 1), you must also order heatsinks (item 11)
as the PCB is not supplied with them. The heatsinks clip onto the voltage regulators
in the positions shown in the drawing below.
