2. Installation
2.4 Optional Connections
EPO Port Connection
2
This optional feature is only for those applications
that 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 and inhibits
transfer to internal bypass. 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
2b
diagram (see ).
Note:
1. If using a cable other than what is supplied,
the cable should not have a resistance of
greater than 5 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.
