ACB Analog Control Board Replacement
To replace the ACB Analog Control Boards:
1. Ensure that all medium voltage and control voltage power to the
drive is isolated and locked out.
2. It is required to remove the transparent sheet on top of the Drive
Processor Module and the Drive Processor Module also before
removing the ACB. Remove the transparent sheet on top of the
DPM by removing the 4 screws.
3. Use static strap before removing any connectors.
4. Remove the connectors J4, J11 and J12 on DPM after proper
identification and marking if necessary. Use the electrical

7. Remove the connectors J1, J2, J3, J4, J5, J6, J7,J8, J9, J10, J12,
J13, J14, J16, J22, J24, J25, J26, J27 on ACB after proper
identification and marking if necessary. Use the electrical
drawing as the reference.
8. Remove the ACB board by removing the 4 screws, and 6
standoffs screwed to support the DPM & encoder interface
board.
9. Follow Steps 8 – 2 in reverse to reinstall the boards back into
the low voltage control cabinet.
10. Apply Low Voltage power and complete a System Test and
Medium Voltage tests to ensure the new board functions properly.
