10.3.10 Using the SSBM EMERGENCY UPM OFF Pushbutton

An SSBM Emergency UPM Off is initiated by the covered, red EMERGENCY UPM OFF pushbutton on the SSBM Control/Monitor Panel. This pushbutton is protected by a clear plastic shield to prevent accidental activation. In an emergency, you can press this pushbutton to instantaneously control the UPM and SSBM output. The SSBM EMERGENCY UPM OFF pushbutton functions differently, depending on the Emergency Power Off (EPO) option specified when ordered. The options available are as follows:

SThe critical load is transferred to bypass and UPMs powered down. UPM breakers CB1, CB2 (MBB) and CB3 open.

SPower to the critical load is de-energized and UPMs powered down. UPM breakers remain CB1, CB2 (MBB) and CB3 open.

SThe critical load is transferred to bypass and UPMs powered down. UPM CB1 breakers trip and the UPM is cut off from utility power. This function requires additional EPO kit available from Powerware.

SPower to the critical load is de-energized and UPMs powered down. UPM CB1 breakers trip and the UPM is cut off from utility power. This function requires additional EPO kit available from Powerware.

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 will deenergize the critical load, power down the UPMs and open UPM breakers CB1, CB2 (MBB), and CB3. The Remote SSBM Emergency Power OFF (REPO) option is not configurable to transfer the critical load to bypass power, if activated.
