3.5.2 TB1 battery interface connections

To install wiring to connections:

1.Verify the UPS system is turned off and all power sources are removed. See Chapter 6, “UPS operating instructions,” for shutdown instructions.

2.If not already accomplished, remove one top screw and two bottom screws securing the UPS left front panel (see Figure 3-1). Lift the panel straight up to remove from the panel hanger bracket at the top of the cabinet.

3.If not already accomplished, remove one top screw and two bottom screws securing the UPS center front panel (see Figure 3-1). Lift the panel straight up to remove from the panel hanger bracket at the top of the cabinet.

4.To gain access to terminal blocksTB1 and the interface entry plates, loosen the screws securing the small top internal safety shield panel and remove the panel.This panel is to the right of the X-Slot Communication Bay (see Figure 3-7 on page 30).

5.To locate the appropriate terminals and review the wiring and termination requirements, see paragraph 2.2.2 on page 14,Table 3-1, and Figure 3-7 through Figure 3-10.

6.If battery cabinets are installed attached to the UPS cabinet, proceed to Step 7; if battery cabinets are installed separated from the UPS cabinet or a battery system is being used, proceed to Step 10.

7.Route the Shunt trip and Aux wiring harness supplied with the battery cabinet from the battery cabinet to the UPS cabinet. Refer to the Powerware 9395 Integrated Battery Cabinet (Model IBC-L) installation manual for battery cabinet wiring access information.

8.Connect the wiring toTB1 terminals.

9.Proceed to Step 15.

10.Remove the UPS cabinet interface entry plates to drill or punch holes (see Figure 3-3 on page 26).

11.Reinstall the interface entry plates.

12.Route the Shunt trip and Aux wiring from the battery cabinet or battery system breaker to the UPS.

13.Connect the wiring to theTB1 terminals.

14.When all wiring is complete, reinstall the small top internal safety shield panel and secure with the cabinet mounted screws.

15.If wiring X-Slot connections, proceed to paragraph 3.5.3; otherwise, proceed to Step 16.

16.Reinstall the left and center front panels removed in previous steps and secure with the retained hardware.
