UPS System InstallationEaton 93PM UPS (20–100 kW, 480V – 100 kW Frame) Installation and Operation Manual P-164000227—Rev 6 www.eaton.com/powerquality 4-234.11.5 Installing External Parallel CAN Control Wiring and ConnectionsTo install wiring:1. Verify the UPS system is turned off and all power sources are removed. See Chapter 6, “UPS OperatingInstructions,“ for shutdown instructions.2. If not already opened, open the front door by lifting the latch from the bottom and turning to the right(counterclockwise) and swing the door open.3. If wiring the external parallel CAN connections using the inter-cabinet wiring access pass-through(line-up-and-match configurations), proceed to Step 4; if wiring the external parallel CAN connectionsusing bottom entry access, proceed to Step 6; if wiring the external parallel CAN connections using topentry access, proceed to Step 12.4. Pass-through Wiring. Route the external parallel CAN control wiring between UPS cabinets through thetop UPS inter-cabinet wiring access pass-through to the UPS external parallel terminals. See Figure 4-6 forUPS wiring access information, and Figure 4-9 and Figure 4-10 for UPS interface terminal locations.5. Proceed to Step 15.6. Bottom Entry Wiring. Remove the bottom interface entry conduit landing plate to drill or punch holes(see Figure 4-11).7. Reinstall the interface entry plate and install the conduit.8. Route the external parallel CAN control wiring through the bottom interface entry conduit landing plate tothe bottom access interface wiring channel along the inside of the front door (see Figure 4-11).9. Route the wiring along the interface wiring channel (see Figure 4-11) to the UPS external parallel terminals.See Figure 4-9 and Figure 4-10 for UPS interface terminal locations.10. Secure the wiring to the wire tie anchors provided (see Figure 4-12) using Zip ties.11. Proceed to Step 15.12. Top Entry Wiring. Remove the top interface entry conduit landing plate to drill or punch holes (seeFigure 4-4).13. Reinstall the interface entry plate and install the conduit.14. Route the external parallel CAN control wiring through the top interface entry conduit landing plate to theUPS external parallel terminals. See Figure 4-4 for wiring access information and Figure 4-9 andFigure 4-10 for UPS interface terminal locations.15. Connect the external parallel CAN wiring to the CAN terminals. See paragraph 3.2.4, Table 4-4, andTable 4-5 for wiring and termination requirements, and Figure 4-18 and Figure 4-19 for wiring informationand terminal assignments.16. If wiring external parallel pull chain connections, proceed to paragraph 4.11.6; if wiring Minislotconnections, proceed to paragraph 4.11.7; if wiring REPO connections, proceed to paragraph 4.12;otherwise, proceed to Step 17.17. Close the UPS outside door and secure the latch.NOTE 1 If installing interface wiring connections between standalone cabinets, conduitmust be installed between each cabinet.NOTE 2 Disconnect terminal block plugs from terminal blocks to wire plugs.
