UPS SYSTEM INSTALLATIONEaton Power Xpert 9395P-1200 UPS (1200 kVA, 1200 kW) Installation and Operation Manual P-164000500 Rev 4 www.eaton.com/powerquality 4-234.8.2 Battery Power WiringC A U T I O NWhen sizing the battery system, do not exceed the internal battery charger capabilities. See Chapter 10,“Product Specifications,” for maximum battery charger currents.MISE EN GARDE!Lors de l’évaluation du système de batterie, ne pas dépasser les capacités internes du chargeur de batteries.Se reporter au chapitre 10 sur les notices techniques pour connaître les tensions maximales du chargeur debatteries.To install wiring to connections:NOTE An installed FI-UPM is always designated as UPM 4.NOTE Battery Cable Routing Requirements using Conduit:* Each conduit must have a Positive, Negative, and Ground conductor. * There must be an equal number of positive and negative conductors in a single conduit. Only. one ground conductor is required in each conduit.Battery Cable Routing Requirements using Raceway:* Positive and negative battery cables must be run side by side in the raceway in an alternatingpattern (+ - + - + - + -).* There must be a ground cable running in the raceway with the battery cables.1. Route the battery cables between the ISBM section and the battery system orbattery disconnect. See Figure 4‐16, Figure 4‐17, Figure 4‐19, and Figure 4‐20 forwiring access information and terminal locations.2. If wiring the UPS for a common battery, proceed to Step 3; if wiring for aseparate battery, proceed to Step 5.3. Using hardware from the external wiring terminal hardware kit (see Table 3‐18),connect the positive, negative, and ground DC power wiring from the batterysystem or disconnect to the ISBM section battery and ground terminals. Useboth sets of terminals shown in Figure 4‐19 as needed. See paragraph 3.2.3 forwiring and termination requirements.4. Proceed to Step 6.5. Using hardware from the external wiring terminal hardware kit (see Table 3‐18),connect the positive, negative, and ground DC power wiring from the batterysystems or disconnects to the ISBM section battery and ground terminals. Useone set of terminals for each UPM as shown in Figure 4‐20. See paragraph 3.2.3for wiring and termination requirements.6. After wiring the UPS system to the facility power and critical load, be sure toground the system according to local and/or national electrical wiring codes.7. If wiring interface connections, proceed to paragraph 4.9; otherwise, proceed toStep 8.8. When all wiring is complete, reinstall the top and bottom safety shield panelsremoved in paragraph 4.8.1, Step 2. Secure with the retained hardware.9. Reinstall the left front panel removed in paragraph 4.8.1, Step 1 and secure withthe retained hardware.
