Component Test Procedures 2-13
Output Power Module. If the drive fails any of these tests, replace the
Gate Driver Board.
8. Repeat steps 3 and 4 with connector X9 and the VH cable. X9 provides
the gate interface for the VH output power transistor in the right-hand
Output Power Module. If the drive fails any of these tests, replace the
Gate Driver Board.
9. Repeat steps 3 and 4 with connector X10 and the cables for WL, VL
and UL. If the drive fails any of these tests, replace the Gate Driver
Board.
10. Repeat steps 1 - 9 for Power Structure #2.
11. Reconnect the DC+ and DC- wires on the bus bars above the Gate
Driver Board on both Power Structures (Refer to Step 4 on page 2-10
).

ATTENTION: Running the drive with the DC bus wires
disconnected will damage the ASIC Boards. You must reconnect
these wires before running the drive.
