6.4.13 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 UPSs, including Bypass, remains off until restarted.

should use this feature only when you want to de-energize the critical load.
To use the REPO switch:
1. Firmly push the red pushbutton until it locks into place. The switch latches into the activated state
(see Figure 6-8).
The rectifier, inverter, battery, and bypass switchgear 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.
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.
