Use one set of terminals for each UPM as shown in Figure 4-26.See paragraph 3.2.2 on page 3−8 for wiring and termination requirements.

6.After wiring the UPS system to the facility power and critical load, be sure to ground the system according to local and/or national electrical wiring codes.

7.If wiring interface connections, proceed to paragraph 4.9; otherwise, proceed to Step 8.
