11. Route the REPO wiring through the bottom interface entry conduit landing plate to the bottom access
interface wiring channel along the inside of the front door (see Figure 25 ).
12. Route the wiring along the interface wiring channel (see Figure 25 ) to the REPO terminals. See Figure 23
and Figure 24 for UPS interface terminal locations.
13. Secure the wiring to the wire tie anchors provided (see Figure 26 ) using Zip ties.
14. Connect the REPO wiring as shown in Table 28 and Figure 33 for a normally-open REPO, or Table 28 and
Figure 34 for a normally-closed REPO. See paragraph 3.2.2 UPS System Power Wiring Preparation for
wiring and termination requirements, and Figure 32 for terminal assignments.
15. If using a normally-closed REPO switch, connect a jumper wire between pins 3 and 4 on the REPO
terminal block.
16. If you are installing multiple REPO switches, wire additional switches in parallel with the first REPO.
17. If required, install wiring from the REPO switch to the trip circuitry of the upstream protective devices. A
second contact block is provided on the REPO switch for this function (see ). The REPO switch wiring
must be in accordance with NEC Article 725 Class 2 requirements.
