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 non-powered switch circuit breakers.
Connect the EPO
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.
