6.3.13 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-energises the critical load and powers down the UPS
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-energise the critical load.
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.
NOTE
To use the REPO switch:
1. The activated REPO switch.
The input, output, battery, and bypass backfeed contactors open, and the power module is turned off
immediately, without asking for verification.
CAUTION
Do not attempt to restart the system after the REPO until the cause of the shutdown has been
identified and cleared.
2. To deactivate the REPO switch in preparation for restarting the UPS.
3. Restart the UPS by following the procedure in paragraph 6.3.1 or 6.3.2.
