3.4.2 Battery 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.If using a Powerware battery cabinet, proceed to Step 2; otherwise, proceed to Step 5.

2.Route and connect the battery cables between the UPS and battery cabinets in accordance with the instructions in the Powerware 9395 Integrated Battery Cabinet (Model IBC-L) installation manual. See Figure 3-3 through Figure 3-5 for wiring access information and terminal locations.

3.Connect the positive, negative, and ground DC power wiring from the battery cabinet to the UPS cabinet battery and ground terminals. See paragraph 2.2.2 on page 14 for wiring and termination requirements.

4.Proceed to Step 7.

5.Route and connect the battery cables between the UPS and the battery system. See Figure 3-3 through Figure 3-5 for wiring access information and terminal locations.

6.Connect the positive, negative, and ground DC power wiring from the battery system to the UPS cabinet battery and ground terminals. See paragraph 2.2.2 on page 14 for wiring and termination requirements.

7.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.

8.If wiring interface connections, proceed to paragraph 3.5; otherwise, proceed to Step 9.

9.When all wiring is complete, reinstall the left front panel removed in paragraph 3.4.1 and secure with the retained hardware.
