SeeChapter 10, “Product Specifications” for maximum battery charger currents.ATTENTION!Lors de l’évaluation du système de batterie, ne pas dépasser les capacités internes du chargeur debatteries. Se reporter au chapitre 10 sur les notices techniques pour connaître les tensionsmaximales du chargeur de batteries.Ne pas installer une armoire endommagée. Signaler lesdommages au transporteur et communiquer avec un représentant du service Eatonimmédiatement.To install wiring to connections:1. Route the battery cables between the ISBM section and the battery system or battery disconnect. SeeFigure 4-12 through Figure 4-17 for wiring access information and terminal locations.2. If wiring the UPS for a common battery, proceed to Step 3; if wiring for a separate battery, proceed toStep 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 battery system or disconnect to the ISBM section batteryand ground terminals. Use both sets of terminals shown in Figure 4-17 as needed. See paragraph 3.2.5 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 battery systems or disconnects to the ISBM sectionbattery and ground terminals. Use one set of terminals for each UPM. See paragraph 3.2.5 for wiring andtermination requirements.6. After wiring the UPS system to the facility power and critical load, be sure to ground the system accordingto local and/or national electrical wiring codes.7. If wiring interface connections, proceed to paragraph 4.9; otherwise, proceed to Step 8.8. When all wiring is complete, reinstall the top and bottom safety shield panels removed in paragraph 4.8.2,Step 2. Secure with the retained hardware.9. Reinstall the left front panel removed in paragraph 4.8.2, Step 1 and secure with the retained hardware.NOTE Battery Cable Routing Requirements using Conduit:l Each conduit must have a Positive, Negative, and Ground conductorl There must be an equal number of positive and negative conductors in a singleconduit. Only one ground conductor is required in each conduit.Battery Cable Routing Requirements using Raceway:l Positive and negative battery cables must be run side by side in the raceway in analternating pattern (+ - + - + - + -).l There must be a ground cable running in the raceway with the battery cables.
