42 Eaton 93PM Integrated Accessory Cabinet-Tie (50 kW and 100 kW IAC-T) Installation and Operation Manual P-164000371—Rev 051. Verify the UPS system is turned off and all power sources are removed. Refer to the applicable Eaton93PM UPS Installation and Operation manual, listed in paragraph 1.7 For More Information, for UPSoperating procedures.2. Open the front door by lifting the latch from the bottom and turning to the right (counterclockwise) andswing the door open.3. Remove the screws securing the internal safety shield panel and remove the panel to gain access to theModule Output Breaker (MOB) input terminals and the Maintenance Isolation Switch (MIS) outputterminals. Retain the hardware for later use.4. If wiring the IAC-T input power terminals using the inter-cabinet wiring access pass-through (line-up-and-match configurations), proceed to Step 5; if wiring the IAC-T input power terminals using the bottom entryaccess, proceed to Step 9; if wiring the IAC-T input power terminals using the top entry access, proceed toStep 13.5. Pass-through Wiring. Route the IAC-T MOB input cables (phase A, B, and C and Ground) from the UPScabinets through the bottom UPS and IAC-T inter-cabinet wiring access pass-through to the IAC-T MOBinput terminals. See Figure 10 for IAC-T wiring access information and Figure 15, Figure 16, or Figure 17for IAC-T terminal locations. See paragraph 3.2.2 IAC-T Power Wiring Preparation, Table 5, Table 6, orTable 7 for IAC-T wiring and termination requirements. Refer to the applicable Eaton 93PM UPS Installationand Operation manual, listed in paragraph 1.7 For More Information, for the UPS terminal locations andtermination requirements.6. Remove the top or bottom conduit plate (see Figure 11) from the IAC-T. Identify all output conduitrequirements and mark their location. Drill and punch all conduit holes in the conduit plate prior tomounting on the IAC-T. Reinstall the conduit plate. Install conduit between the IAC-T and the critical load orIntegrated Accessory Cabinet-Distribution (IAC-D). Pull the wiring through conduit into the wiring area.7. Route the output cables (phase A, B, and C and Ground) from the IAC-T through the top or bottom of thecabinet to the critical load. See Figure 15, Figure 16, or Figure 17 for IAC-T terminal locations. Seeparagraph 3.2.2 IAC-T Power Wiring Preparation, Table 5, Table 6, or Table 7 for IAC-T wiring andtermination requirements. Refer to the Eaton 93PM Integrated Accessory Cabinet-Distribution (50 kW, 100kW, 150 kW, and 200 kW IAC-D) Installation and Operation Manual, listed in paragraph1.7 For More Information, for IAC-D conduit and terminal locations and termination requirements.8. Proceed to Step 16.9. Bottom Entry Wiring. Remove the bottom conduit plate (see Figure 11) from the inside bottom of theIAC-T. Identify all conduit requirements (both input and output) and mark their location. Drill and punch allconduit holes in the bottom conduit plate prior to mounting on the IAC-T. Install the conduit plate andinstall all conduit runs into the plate. Pull the wiring through conduit into the wiring area.10. Route the IAC-T MOB input cables (phase A, B, and C and Ground) from the UPS cabinets through thebottom of the IAC-T to the IAC-T MOB input terminals. See Figure 10 for IAC-T wiring access informationand Figure 15, Figure 16, or Figure 17 for IAC-T terminal locations. See paragraph3.2.2 IAC-T Power Wiring Preparation, Table 5, Table 6, or Table 7 for IAC-T wiring and terminationrequirements. Refer to the applicable Eaton 93PM UPS Installation and Operation manual, listed inparagraph 1.7 For More Information, for the UPS terminal locations and termination requirements.11. Route the output cables (phase A, B, and C and Ground) from the IAC-T through the bottom of the cabinetto the critical load. See Figure 15, Figure 16, or Figure 17 for IAC-T terminal locations. See paragraph3.2.2 IAC-T Power Wiring Preparation, Table 5, Table 6, or Table 7 for IAC-T wiring and terminationrequirements. Refer to the Eaton 93PM Integrated Accessory Cabinet-Distribution (50 kW, 100 kW, 150kW, and 200 kW IAC-D) Installation and Operation Manual, listed in paragraph 1.7 For More Information,for IAC-D conduit and terminal locations and termination requirements.12. Proceed to Step 16.13. Top Entry Wiring. Remove the top conduit plate (see Figure 11) from the top of the IAC-T. Identify allconduit requirements (both input and output) and mark their location. Drill and punch all conduit holes inInstallation
