The auxiliary contacts must be wired to the BPM from the UPS for proper functionality. These auxiliary contacts
signal the UPS to go to Internal Bypass mode to provide a synchronized transfer. Failure to wire the auxiliary
contacts can be dangerous and result in system failure.
If the UPS is in standby mode and the bypass auxiliary contact is activated, the UPS output will become
energized.
1. Route the maintenance bypass signal wires in a conduit from the bypass module to the communication
signal terminal (CN13) on the rear of the UPS ( See
electrical code.
2. Place the signal wires through the proper conduit or grommet to the terminal block in the BPM.
