UPS SYSTEM INSTALLATION

4.Locate the external wiring terminal hardware kit packed on the bottom left side of the ISBM section.

5.If installing an UPS with separate rectifier feeds, proceed to Step 6; otherwise, proceed to Step 8.

NOTE On an UPS that is configured for separate rectifier inputs all sources that feed the separate rectifier inputs must be derived from a common ground point.

6.Connect phase A, B, and C rectifier input power wiring from the utility source to each UPM rectifier input terminal block in the UPS cabinet. See paragraph 3.2.2 on page 3−8, Table 3-6on page 3−11, and Table 3-12on page 3−14 for wiring and termination requirements.

7.Proceed to Step 9.

8.Using hardware from the external wiring terminal hardware kit (see Table 3-10on page 3−14), connect phase A, B, and C rectifier input power wiring from the utility source to the rectifier input terminals in the ISBM section. See paragraph 3.2.2 on page 3−8 for wiring and termination requirements.

9.If installing an UPS configured as an Input Output Module (IOM), proceed to Step 11; otherwise, proceed to Step 10.

10.Using hardware from the external wiring terminal hardware kit (see Table 3-10on page 3−14), connect phase A, B, and C, and Neutral (if required) bypass input power wiring from the utility source to the bypass input terminals and neutral terminals in the ISBM section. See paragraph 3.2.2 on page 3−8 for wiring and termination requirements.

11.If wiring a distributed bypass system, proceed to Step 12; otherwise, proceed to Step 14.

C A U T I O N

Distributed bypass system wiring length should be in accordance with Figure 4-19,to ensure approximately equal current sharing when in Bypass mode.

12.Using hardware from the external wiring terminal hardware kit (see Table 3-10on page 3−14), connect phase A, B, and C, and Neutral power wiring from the output and neutral terminals of each UPS unit to the customer−supplied tie cabinet or load distribution panel. See paragraph 3.2.2 on page 3−8 for wiring and termination requirements.

13.Proceed to paragraph 4.8.2.

14.Using hardware from the external wiring terminal hardware kit (see Table 3-10on page 3−14), connect phase A, B, and C, and Neutral (if required) power wiring from output terminals and neutral terminals to the critical load. See

paragraph 3.2.2 on page 3−8 for wiring and termination requirements.

15.Proceed to paragraph 4.8.2.
