Installation Notes

Verify the board part number (1KHW002356R0001) and revision against the drive spare-parts list before installation.
De-energize the drive and confirm DC-link discharge before handling the board; use ESD precautions.
Install the board in its designated slot; seat the connector(s) fully.
Confirm the 48 V DC input within the allowable range (+20%/−15%) before power-up.
After power-up, verify the internal rail voltages and absence of undervoltage/overvoltage alarms via the drive diagnostics before returning to service.
