10--7 Powerware 9315 Parallel Capacity/Redundant System with PHP SSBM
164201373 Rev. A 092402
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.
10.2.11 To Use the SSBM EMERGENCY UPM OFF Pushbutton
1. Raise the clear plastic shield covering the red SSBM EMERGENCY UPM OFF
pushbutton on the SSBM Control Panel.
2. Press the EMERGENCY UPM OFF pushbutton.
The breakers and contactors open (you can hear them opening and closing) and the
Emergency UPM Off PUSH IN TO RESET pushbutton on the SSBM Control Panel
pops out.
10.2.12 Resetting the Parallel Capacity/Redundant
System after an EMERGENCY UPM OFF
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.
To reset the Parallel Capacity/Redundant system:
1. Press the Emergency UPM Off PUSH IN TO RESET pushbutton until it clicks
in and remains recessed.
2. On the UPMs, move the CB1 switches from the center (tripped) position to
OFF. The switches should be difficult to move from the TRIPPED position.
3. The Parallel Capacity/Redundant system is now reset. To restart the Parallel
Capacity/Redundant system, follow the procedure at the beginning of this
Chapter.
