10.3.7Using the UPM EMERGENCY UPM OFF Pushbutton
NOTE: The UPM EMERGENCY UPM OFF pushbutton will only interrupt the ability for that module to deliver power to the critical bus. The redundant modules continue to support the critical load.
Emergency UPM shutdown is initiated by the covered, red UPM EMERGENCY UPM OFF pushbutton on the UPM Monitor Panel.
