NOTE Before installing a REPO, 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 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:
