UPS SYSTEM INSTALLATIONEaton Power Xpert 9395P-1200 UPS (1200 kVA, 1200 kW) Installation and Operation Manual P-164000500 Rev 4 www.eaton.com/powerquality4-10NOTE Two cable lugs will be connected to each terminal stud. When connecting the cable lugs, install thefirst lug on the stud with the raised barrel portion facing the back of the cabinet. Install the second lug withthe raised barrel portion facing the front of the cabinet.6. Locate the intercabinet wiring terminal hardware kit packed on the bottom rightside of the ISBM section.7. Using hardware from the intercabinet wiring terminal hardware kit (seeTable 3‐16), connect phase A, B, and C cable lug connections to the AC Input toUPMs terminals. Follow the callout details in Figure 4‐9 to connect the correctcable lug to the proper terminals. See paragraph 3.2.3 for wiring and terminationrequirements.8. Locate the 1G3, 2G3, and 3G3 power wiring harnesses. Route these harnessesthrough the wiring access in the right side panel of the ISBM section to the DCInput to UPMs terminals. See Figure 4‐8 for terminal locations.NOTE When connecting the UPM battery cables, verify the cables are connected to the correct terminals.9. Using hardware from the intercabinet wiring terminal hardware kit (seeTable 3‐16), connect the positive and negative cable lug connections to the DCInput to UPMs terminals. Follow the callout details in Figure 4‐10 to connect thecorrect cable lug to the proper terminals. See paragraph 3.2.3 for wiring andtermination requirements.NOTE AC output intercabinet power wiring harnesses are supplied attached to the interior left side panelof the UPM section (see Figure 4‐5).10. Locate the 1G4, 1G5, 2G4, 2G5, 3G4, and 3G5 power wiring harnesses. Removethe front two columns of wire ties securing the cables to facilitate routing cablesto the AC Output from UPMs terminals. See Figure 4‐8 for terminal locations.NOTE Two cable lugs will be connected to each terminal stud. When connecting the cable lugs, install thefirst lug on the stud with the raised barrel portion facing the back of the cabinet. Install the second lug withthe raised barrel portion facing the front of the cabinet.11. Using hardware from the intercabinet wiring terminal hardware kit (seeTable 3‐17), connect phase A, B, and C cable lug connections to the AC Outputfrom UPMs terminals. Follow the callout details in Figure 4‐11 to connect thecorrect cable lug to the proper terminals. See paragraph 3.2.3 for wiring andtermination requirements.12. Install the remaining hardware (three washers, conical washers, and nuts) ontothe AC Input to UPMs terminals designated for the four UPM model and securethe hardware (see Figure 4‐9). This hardware is used by an Eaton CustomerService Engineer to install a Field Installed UPM (FI-UPM).13. Locate the ground braid in the bottom left front corner of the UPM section. Theground braid is secured at the factory to the UPM section ground bolt. Route theground braid through the wiring access in the right side panel of the ISBMsection to the ground bolt in the ISBM section.14. Connect the ground braid to the ISBM section ground bolt and secure.
