A parallel system emergency power-off is initiated by the REPO pushbutton switch. In an emergency, you can use this switch to control the UPM outputs. The REPO switch de-energizes the critical load and powers down the UPMs immediately, without asking for verification.

The UPMs, including Bypass, remain off until restarted.
