Configuration
Connect the Emergency Power Off option
The Emergency Power Off (EPO) option is a safety feature that will immediately remove power to all
connected equipment. When the 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 when wiring the EPO.
1. Use the EPO terminal block supplied with the UPS.
2. Insert one wire from the EPO cable into the +24 terminal, and one wire into the IN
terminal of the EPO terminal block.
3. Secure the connection by tightening the screws on the EPO terminal block.
4. Plug the terminal block into the UPS.
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.
