Using the REMOTE EMERGENCY POWER OFF
Switch
An Emergency Power Off is initiated by Remote Emergency Power OFF (REPO)
pushbutton switch. In an emergency, you can use this switch to control the output
of the UPMs. The REPO switch de-energizes the critical load and powers down the
UPMs, without asking for verification.
The UPMs, including Bypass, remain off until restarted.
4.4.9.1 To Use the REPO Switch
WARNING:
All power to the critical load is lost when this switch is activated. You should use this
feature only in an emergency or when you want to de-energize the critical load.
NOTE: The following instructions are for the Powerware supplied REPO switch. If a
customer supplied REPO switch is used it may not activate in the same
manner. If this is the case, refer to the operating instructions provided with
the switch.
1.
Press the REPO pushbutton switch.
The input, output, battery and bypass backfeed contactors in the UPMs, open and the
PPU in the UPMs are turned off immediately, without asking for verification.
CAUTION:
Do not attempt to restart the system after REPO until the cause of the
emergency has been identified and cleared.
2.
To restart the UPMs after using the REPO pushbutton, reset the REPO switch
by rotating the switch and then follow the procedure, in paragraphs 4.4.1 or
4.4.2.
