SOLA 4000 - Operating Panel
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).
