Battery Power Wiring

When sizing the battery system, do not exceed the internal battery charger capabilities. See Chapter 9,
"UPS Maintenance" for maximum battery charger currents.
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
alternating pattern (+ - + - + - + -).
* There must be a ground cable running in the raceway with the battery cables.
1. If using an Eaton battery cabinet, proceed to Step 2; otherwise, proceed to Step 4.
2. Route and connect the battery cables between the UPS and battery cabinet or battery disconnect
according to the instructions in the Eaton 9395 Integrated Battery Cabinet (Model IBC-L) Installation
Manual, listed in paragraph 1.7 on page 1--8. See Figure 4-4 and Figure 4-6 for wiring access information
and terminal locations.

4. Route and connect the battery cables between the UPS and battery system or battery disconnect. See
Figure 4-4 and Figure 4-6 for wiring access information and terminal locations.
5. If wiring the UPS for a common battery, proceed to Step 6; if wiring for a separate battery, proceed to
Step 8.
6. Connect the positive, negative, and ground DC power wiring from the battery cabinet or disconnect to the
UPS cabinet battery and ground terminals. Use both sets of terminals shown in Figure 4-9 as needed. See
paragraph 3.2.3 for wiring and termination requirements.
7 . Proceed to Step 9.
8. Connect the positive, negative, and ground DC power wiring from the battery cabinets or disconnects to
the UPS cabinet battery and ground terminals. Use one set of terminals for each UPM as shown in
Table 4-11. See paragraph 3.2.3 for wiring and termination requirements.
9. 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.
10. If wiring interface connections, proceed to paragraph 4.7; otherwise, proceed to Step 11.
11. When all wiring is complete, reinstall the safety shield panel removed in paragraph 4.6.2, Step 2. Secure
