9.16 Using the REMOTE EMERGENCY POWER OFF
Switch
An UPS Emergency Power Off is initiated by Remote Emergency Power OFF
(REPO) pushbutton switch . In an emergency, you can use this switch to control
the UPS output. The REPO switch de-energizes the critical load and powers down
the UPS immediately, without asking for verification.
The UPS, including Bypass, remains off until restarted.
9.16.1 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 open and the PPU is
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 UPS after using the REPO pushbutton, reset the REPO switch by
rotating the switch and then follow the procedure, in paragraphs 9.2 or 9.3.
