Emergency Power Off
The emergency power off (EPO) feature is user configurable. EPO provides immediate de-energizing of
connected equipment from a remote location, without switching to battery operation.
1. Use the EPO connector supplied with the UPS.
2. Use a normally-open contact to connect the +24 terminal to the IN terminal.
3. Wire the four-pin connector to the EPO system.
The EPO interface is a Safety Extra Low Voltage (SELV) circuit. Connect it only to other SELV
circuits. The EPO interface monitors circuits that have no determined voltage potential. Such closure
circuits may be provided by a switch or relay properly isolated from the utility. To avoid damage to the
UPS, do not connect the EPO interface to any circuit other than a closure type circuit.
Use one of the following cable types to connect the UPS to the EPO switch.
• CL2: Class 2 cable for general use.
• CL2P: Plenum cable for use in ducts, plenums, and other spaces used for environmental air.
• CL2R: Riser cable for use in a vertical run in a floor-to-floor shaft.
• CLEX: Limited use cable for use in dwellings and for use in raceways.
• For installation in Canada: Use only CSA certified, type ELC, (extra-low voltage control cable).
• For installation in other countries: Use standard low-voltage cable in accordance with national and
local regulations.
SERIAL PORT USB PORT 120/230 V models: Use only the supplied cable to connect to the serial
port. A standard serial interface cable is incompatible with the UPS.
100 V models: Users may purchase software and cables as an
accessory to the UPS. Refer to the APC Web site, www.apc.com for
information on accessories.
Serial and USB ports cannot be used simultaneously.
