The SSBM (including Bypass) remains locked off until you reset the EMERGENCY UPM OFF pushbutton.
To restart the UPS after pressing the EMERGENCY UPM OFF pushbutton, follow the procedure “Resetting the Parallel Capacity/Redundant System after Emergency UPM Off”, of this chapter, before starting the system.
NOTE: The Remote SSBM Emergency Power Off (REPO) option functions differently than the SSBM EMERGENCY UPM OFF pushbutton on the SSBM control panel. If activated, the REPO option deenergizes the critical load, powers down the UPMs and opens UPM breakers CB1 and contactor K3. The Remote SSBM Emergency Power (REPO) option is not configurable to transfer the critical load to bypass source if activated.

CAUTION:
Do not attempt to restart the system after Emergency UPM Off until the cause
of the emergency has been identified and cleared.
The Emergency UPM Off PUSH IN TO RESET pushbutton is a small white button on the SSBM Control Panel. The PUSH TO RESET pushbutton pops out when the Emergency UPM Off pushbutton on the SSBM Control Panel is activated.
