Connect the Signal Cables for EPO (Emergency Power Off)

  1. Remove the front bottom gland plate and the front bottom brush plate from the UPS.
  2. Perform one of the following:
    • For installation without conduits: Reinstall the brush plate.
    • For installation with conduits: Drill a hole in the gland plate for conduits, install conduits, and reinstall the gland plate.
  3. Route the Class 2/SELV signal cables from the building EPO through the front gland plate/brush plate and connect to the terminal block TB1 and TB2.

    The EPO circuit is considered Class 2/SELV. Class 2/SELV circuits must be isolated from the primary circuitry. Do not connect any circuit to the EPO terminal block unless it can be confirmed that the circuit is Class 2/SELV.

    EPO Configuration – Normally Closed (NC) Connection

    The EPO input supports 24 VDC.

    NOTE: The default setting for the EPO activation is to turn off the inverter. If you want the EPO activation to transfer the UPS into forced static bypass operation instead, please contact Schneider Electric.
