5. If you are installing multiple REPO stations, wire additional stations in parallel with the first REPO station.
6. If required, install ½" conduit and wiring from the second contact block in the REPO station to trip circuitry
of other equipment, such as upstream protective devices, facility monitoring devices, or alarms. Using the
contact block that was not used for the UPS EPO wiring will help maintain isolation between the control
systems.
A normally-open (NO) contact and a normally-closed (NC) contact are provided, and the two are electrically
isolated. If single-pole, double-throw action is desired, one side of the NO contact can be jumpered to one
side of the NC contact to form the common connection point. REPO switch wiring must be according to
UL Class I requirements.
7. Secure the UPS by reversing all steps taken to prepare it for a REPO station installation.
