Parallel UPS Wiring
To hardwire the UPS in a parallel capacity and/or redundant system:
1. Remove the UPS conduit landing box from the rear panel and retain (see Figure 14).
2. Punch two holes in the conduit landing box for the input and output conduit using a Greenlee punch or
similar device.
3. Route the wiring from the back of the UPS, through the wiring tray, to the front of the UPS.
4. Hardwire the input terminations for the UPS. See Table 1 on page 35 for wiring specifications.
For a detailed view of the UPS terminal block, see Figure 23 on page 36. See Figure 15 or Figure 16 for a
parallel wiring diagram.
5. Remove any Tie Cabinet covers and install conduit for the Tie Cabinet.
