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).
