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 inverter.
Using the cable provided, connect the EPO port of
your UPS (see
2a
) to a user-supplied normally
closed or normally open switch according to the
circuit diagram (see
2b
). The EPO port is not a
phone line surge protector; do not connect a phone
line to this port.
