Optional Connection continued 2 EPO Port Connection 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 diagram (see 2b). 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.

Optional Connection

EPO Port Connection
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 diagram (see
2b
).
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.
