CONNECT THE EPO (EMERGENCY POWER OFF) OPTION

The output power can be disabled in an emergency by closing a switch connected to the EPO.

Adhere to national and local electrical codes when wiring the EPO.

Wiring must be performed by a qualified electrician.

EPO switch

The EPO switch is internally powered by the UPS for use with non-powered switch circuit breakers.

The EPO circuit is considered a Class 2 circuit, (UL, CSA standards) and a SELV circuit (IEC standard).

Both Class 2 and SELV circuits must be isolated from all primary circuitry. Do not connect any circuit to the EPO terminal block unless it can be confirmed that the circuit is Class 2 or SELV.

If circuit standard cannot be confirmed, use a contact closure switch.

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 local regulations.
