6.43 IGBT Inverter Q3/Q4 Driver Circuit Board (PCB8) Replacement Procedure
Refer to figure 6-49.
to remove pCB8, do the following:
1. Remove the Main Circuit Board, per page 6.13.
2. Remove connector CN1, CN2 and CN4 from PCB8.
3. Cut cable ties securing ribbon cable at CN3 to GREEN ground wires.
4. Remove the four (4) screws securing PCB8 to the chassis. As the board is lifted off the chassis, disconnect
connector CN5.
To replace PCB8, reverse the removal steps above. It may be helpful to connect CN2 and CN5 before seating the board
fully back onto the chassis.
