Emergency Power Off (EPO) Option
The output power can be disabled in an emergency by closing a switch connected to the EPO.
Note: Adhere to national and local electrical codes when wiring.
The switch should be connected in a normally open switch contact. External voltage is not required; the switch is powered by a 12 V internal power supply. A closed switch draws 2 mA of current.
The EPO switch is internally powered by the uninterruptible power supply for use with
EPO
Switch
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 the circuit standard cannot be confirmed, use a contact closure switch.
Use one of the following cable types to connect the uninterruptible power supply 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 a standard
