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.
connected equipment from a remote location, without switching to battery operation.
Use a normally-open contact to connect the EPO COM terminal to the EPO 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.

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.
