After the system has been placed into SERVICE mode, it must be returned to UPS state to resume normal
operation.
It is critical that the following steps are followed to ensure correct and safe operation.
Do not attempt to push the red interlock button or attempt to move the bypass switch handle if the UPS is
operating on battery power.
Refer to the UPS user guide or call the Eaton service help desk for specific BPM to UPS signal functionality.
