Connecting 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.
Rockwell Automation recommends Allen-Bradley Catalog Number 800F Emergency Stop Operator as the interface to the EPO
to connector.
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).
