EVO have the EPO (Emergency Power OFF) connector (2 terminals connector) on the rear. This
permits to immediately switch the UPS OFF from a distance in case of emergency.
To use EPO function is very simple: it is sufficient to connect an external switch to the EPO
terminal(see Figure 3 – Rear Side): if the switch is CLOSED the UPS works normally. If on the
contrary, the switch is OPEN then the UPS turns OFF immediately. To switch ON the UPS again
it is necessary to close the EPO switch and then manually restart the UPS from the front panel.
The EPO terminals are isolated and do not need an external feeding voltage.
