EPO Port Connection
This optional feature is only for those
applications requiring 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 and
inhibits transfer to internal bypass. Using the
provided cable, connect the UPS EPO port
to a user-supplied, normally-closed or normally-
open switch according to the circuit diagram
3b .
Note:
1. If using a cable other than what is supplied, the
cable should not exceed 350 feet or have a
resistance of greater than 10 ohms.
2. If a non-latching EPO switch is used, the EPO must
be held for a minimum of 1 second. This does not
apply to a latching EPO switch.
CAUTION: The EPO port is not a
phone line surge suppressor; do
not connect a phone line to this
port.
