EPO Port Connection
This optional feature is only for those applications
which require connection to a facility’s Emergency
Power Off (EPO) circuit. When the UPS is connected
to this circuit, it enables emergency shutdown of
the UPS's inverter.
Using the cable provided, connect the EPO port of
your UPS (see
4a
) to a user-supplied normally
closed or normally open switch according to the
circuit diagram (see
4b
). The EPO port is not a
phone line surge suppressor; do not connect a
phone line to this port.

press and hold the POWER button for one second.** Then unplug the
