Installing a REPO Switch

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 4-28
shows a REPO switch.
To Install a REPO switch:
1. Verify the UPS system is turned off and all power sources are removed. See Chapter 7, "UPS Operating
Instructions" for shutdown instructions.
2. Securely mount the REPO switch. Recommended locations include operator's consoles or near exit
doors. See Figure 3-17 for enclosure dimensions and wiring knockouts.
3. Unfasten the front door latch and swing the door open (see Figure 4-1).
4. Remove the door. Remove the retaining screw located inside the door at the bottom hinge pivot point,
then lift the door off. Retain the hardware for later use.

NOTE Before installing a REPO switch, verify that the UPS was installed according to the
instructions in paragraphs 4.2 through 4.9.
NOTE When installing the REPO switch, you must install conduit between the device and
the UPS cabinet for wiring the switch.
NOTE Remove the UPS cabinet interface entry conduit landing plates to drill or punch
holes (see Figure 4-16).
NOTE The REPO switch must be a normally-open or normally-closed latching-type switch
not tied into any other circuits.
NOTE This procedure is intended to be used for the installation of the Eaton-supplied
REPO switch. If installing another manufacturer's switch, use this procedure only as
a guide.
NOTE The REPO switch wiring must be in accordance with NEC Article 725 Class 2
requirements.
