Installing a Remote Emergency Power-off Control

A latching-type Remote Emergency Power-off (REPO) switch can be used in an
emergency to shut down the UPS and remove power to the critical load from a
location away from where the UPS is installed. Figure 5‐1 shows an Eaton REPO
switch.

NOTE Before installing a REPO switch, verify that the UPS was installed according to the instructions in
Chapter 3, "Installing the UPS System."
To install a REPO station:
1. Verify that the UPS system is turned off and all power sources are removed. See
Chapter 9, "UPS Operating Instructions," for shutdown instructions.
2. Securely mount the REPO station. Recommended locations include operator's
consoles or near exit doors. See Figure A‐25 on page A-37 for enclosure
dimensions and wiring knockouts.
3. Install wiring from the REPO station using ½" conduit through the cable entry
knockout in the top of the UPS Output/Inverter cabinet. See Appendix A for
conduit landing area, terminal board location, and terminal wiring assignments.
4. Connect the REPO wiring as shown in Table 5‐1 and Figure 5‐2.
