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.
