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.￿
