1.6 Emergency Power Off

In case of emergency it is possible to switch off the complete UPS system. This is done by simultaneously pressing the "EMER- GENCY POWER OFF" (E.P.O.) push-buttons located on the operating panel. This function provides UPS disconnection from the load and galvanically isolates the UPS from the battery.

In the case of parallel and hot-standby configurations, activating EPO on one unit automatically switches OFF the entire system (when IUG is closed on that unit).

When E.P.O. is activated, dangerous voltages will still be present within the UPS cabinet unless the input supply circuit breaker(s) have a shunt trip circuit connected with the EPO circuit (see JUE 401066 section 1.5).
