Emergency Power Off (EPO)
The Emergency Power Off (EPO) option is a safety feature that will immediately remove power to all connected equipment. When EPO button is pushed, all connected equipment will immediately turn off and will not switch to battery power.
Adhere to all national and local electrical codes. Wiring must be performed by a qualified electrician.
The switch should be connected in a normally open switch contact. External voltage is not required; the switch is driven by 12 V internal supply. In closed condition, 2 mA of current are drawn.
The EPO switch is internally powered by the UPS for use with
Connect the EPO
The EPO connector is located on the rear panel of the UPS.
1. Strip insulation from one end of each wire to be used for connecting EPO.
2.Insert a screwdriver into the slot above the terminal to be wired. Insert stripped wire into terminal. Remove screwdriver to secure wire in terminal. Repeat for each terminal.
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
•CLEX: Limited use cable for use in dwellings and for use in raceways.
•For installation in Canada: Use only CSA certified, type ELC,
•For installation in other countries: Use standard
