Output Contact Ratings:
A standard serial interface cable is incompatible with the UPS. Use the cable supplied with the unit.
The relays are connected from the common (COM) to the normally closed (NC) pins.When the unit enters a low battery or on battery state, the appropriate relay will transition and connect the common (COM) to the normally open (NO) pin.
The Contact Closure Port connection will automatically disable when a Network Management Card or the Serial Port connection are used.

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
