4.8.3 Battery Power Wiring
CAUTION
When sizing the battery system, do not exceed the internal battery charger capabilities. See Chapter 10,
“Product Specifications” for maximum battery charger currents.
To install wiring to connections:
1. Route the battery cables between the ISBM section and the battery system or battery disconnect. See
Figure 4-19, Figure 4-20, and Figure 4-22 or Figure 4-23 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 to
Step 5.
3. Using hardware from the external wiring terminal hardware kit (see Table 3-13), connect the positive,
negative, and ground DC power wiring from the battery system or disconnect to the ISBM section battery
and ground terminals. Use both sets of terminals shown in Figure 4-22 as needed. See paragraph 3.2.3 for
wiring and termination requirements.
4. Proceed to Step 6.
5. Using hardware from the external wiring terminal hardware kit (see Table 3-13), connect the positive,
negative, and ground DC power wiring from the battery systems or disconnects to the ISBM section
battery and ground terminals. Use one set of terminals for each UPM as shown in Figure 4-23. See
paragraph 3.2.3 for wiring and termination requirements.
6. After wiring the UPS system to the facility power and critical load, be sure to ground the system according
to 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 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
alternating pattern (+ - + - + - + -).
* There must be a ground cable running in the raceway with the battery cables.
