NNOOTTEE Before installing a REPO switch, verify that the UPS was installed according to the
instructions in Chapter 4 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 88 for enclosure dimensions and wiring knockouts.
3. Install wiring from the REPO station using 1/2-inch conduit through the cable entry knockout in the top of
the UPS cabinet. See Chapter 15 Installation Information for conduit landing area, terminal board location,
and terminal wiring assignments.
4. Connect the REPO wiring as shown in Table 1 and Figure 6.
