UPS SYSTEM INSTALLATION

3.Route the input and output cables through either the top or bottom of the cabinet to the UPS terminals. See Figure 4-16through Figure 4-19for wiring access information and terminal locations.

Top Access Wiring. Remove the top conduit plate from the top of the ISBM section. Identify all conduit requirements and mark their location. Drill and punch all conduit holes in the top conduit plate prior to mounting on the ISBM section. Install the conduit plate and install all conduit runs into the plate. Pull wiring through conduit into the ISBM section wiring area.

Bottom Access Wiring. Remove the bottom conduit plate from the inside bottom of the ISBM section. Identify all conduit requirements and mark their location. Drill and punch all conduit holes in the bottom conduit plate prior to mounting on the ISBM section. Install the conduit plate and install all conduit runs into the plate. Pull wiring through conduit into the ISBM section wiring area.

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

4.Using hardware from the external wiring terminal hardware kit (see Table 3-11on page 3−15), 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.

5.Using hardware from the external wiring terminal hardware kit (see Table 3-11on page 3−15), 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.

6.If wiring a distributed bypass system, proceed to Step 7; otherwise, proceed to Step 9.

C A U T I O N

Distributed bypass system wiring length should be in accordance with Figure 4-17,to ensure approximately equal current sharing when in Bypass mode.

7.Using hardware from the external wiring terminal hardware kit (see Table 3-11on page 3−15), 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.

8.Proceed to paragraph 4.8.2.

9.Using hardware from the external wiring terminal hardware kit (see Table 3-11on page 3−15), 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.

10.Proceed to paragraph 4.8.2.
