Retain trim plate and hardwarefor later use.5. If wiring the IAC-D input power terminals using the inter-cabinet wiring access pass-through(line-up-and-match configurations), proceed to Step 6; if wiring the IAC-D input power terminals using thebottom entry access, proceed to Step 8; if wiring the IAC-D input power terminals using the top entryaccess, proceed to Step 11.6. Pass-through Wiring. Route the IAC-D input cables (phase A, B, and C and Ground) from the UPS cabinetthrough the bottom UPS and IAC-D inter-cabinet wiring access pass-through to the IAC-D input terminals.See Figure 4-2 for IAC-D wiring access information and Figure 4-4 for IAC-D terminal locations.

Drill and punch allconduit holes in the bottom conduit plate prior to mounting on the IAC-D. Install the conduit plate andinstall all conduit runs into the plate. Pull the wiring through conduit into the wiring area.9. Route the output cables (phase A, B, and C and Ground) from the UPS through the bottom of the cabinetto the IAC-D input terminals. See Figure 4-4 for IAC-D terminal locations. See paragraph 3.2.2, Table 3-4,and Table 3-8 for IAC-D wiring and termination requirements. Refer to the applicable Eaton 93PM UPSmanual, listed in paragraph 1.7, for the UPS terminal locations and termination requirements.10. Proceed to Step 13.11. Top Entry Wiring. Remove the top conduit plate (see Figure 4-3) from the top of the IAC-D. Identify allconduit requirements (both input and output) and mark their location. Drill and punch all conduit holes inthe top conduit plate prior to mounting on the sidecar. Install the conduit plate and install all conduit runsinto the plate. Pull the wiring through the conduit into the wiring area.12. Route the output cables (phase A, B, and C and Ground) from the UPS through the top of the cabinet tothe IAC-D input terminals. See Figure 4-4 for IAC-D terminal locations. See paragraph 3.2.2, Table 3-4, andTable 3-8 for IAC-D wiring and termination requirements. Refer to the applicable Eaton 93PM UPS manual,listed in paragraph 1.7, for the UPS terminal locations and termination requirements.NOTE 1 Input power wiring is routed through the inside bottom of the IAC-D and UPS forline-up-and-match configurations or wiring can be installed using conduit betweenthe cabinets for standalone installations.NOTE 2 Remove the IAC-D conduit landing plates to drill or punch conduit holes, or removeknockouts in the conduit plate (see Figure 4-3).
