7.5.13 Using the Remote Emergency Power-off Switch
A UPS emergency power-off is initiated by the 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 UPSs immediately, without asking for verification.
The UPS, including Bypass, remains off until restarted.
CAUTION
All power to the critical load is lost when the REPO switch is activated in the following step. You
should use this feature only when you want to de-energize the critical load.
To use the REPO pushbutton switch:
1. Firmly push the red pushbutton until it locks into place. The switch latches into the activated state.
The input, output, and bypass backfeed contactors open, the battery breaker or disconnect is tripped, and
the power module is turned off immediately, without asking for verification on all UPSs.
CAUTION
Do not attempt to restart the system after latching the REPO pushbutton switch until the cause of
the shutdown has been identified and cleared.
2. To deactivate the REPO pushbutton switch in preparation for restarting the UPS, insert the supplied key
and rotate clockwise until the red pushbutton releases). To remove the key, rotate the key back to the
vertical position.
3. Restart the UPSs by following the procedure in paragraph 7.5.1 or 7.5.2.
WARNING
Power is present inside the UPS cabinet until the upstream input feeder circuit breaker is opened.
NOTE The following instructions are for the Eaton-supplied REPO switch. If a
customer-supplied REPO switch is used, it may not activate in the same manner;
refer to the operating instructions provided with the switch.
