4.12 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 4-18
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 6, “UPS Operating
Instructions,“ for shutdown instructions.
2. Securely mount the REPO switch. Recommended locations include operator's consoles or near exit
doors. See Figure 3-4 for enclosure dimensions and wiring knockouts.
3. To locate the appropriate terminals and review the wiring and termination requirements, see
paragraph 3.2.3, Table 4-3, Figure 4-10, Figure 4-11, and Figure 4-19.
Figure 4-18. REPO Switch
NOTE 1 Before installing a REPO switch, verify that the UPS was installed according to the
instructions in paragraphs 4.2 through 4.11.
NOTE 2 When installing the REPO switch, you must install conduit between the device and
the UPS cabinet for wiring the switch.
NOTE 3 The REPO switch must be a normally-open or normally-closed latching-type switch
not tied into any other circuits.
NOTE 4 This procedure is intended for installing the Eaton-supplied REPO switch. If
installing another manufacturer's switch, use this procedure, and Figure 4-20 and
Figure 4-21 as a guide.
NOTE 5 The REPO switch wiring must be in accordance with NEC Article 725 Class 2
requirements.
