NOTE When installing interface wiring for TB1, TB2, and TB3 connections, conduit must be
installed between each device and the UPS cabinet.
NOTE Interface wiring must be installed from the top of the UPS cabinet.
To install wiring to connections:
1. Verify the UPS system is turned off and all power sources are removed. See
Chapter 7 UPS Operating Instructions for shutdown instructions.
2. If not already opened, unfasten the front door latch and swing the door open (see Figure 16).
3. If not already removed, remove the door. Remove the retaining screw located inside the door at the
bottom hinge pivot point, then lift the door off. Retain the hardware for later use.
4. Terminal block TB3 is accessible on the left side of the X-Slot communication bay. To gain access to
terminal block TB1, TB2, and the left interface entry conduit landing plates, remove the screws securing
the top internal safety shield panel and remove the panel. Retain the hardware for later use (see Figure 37).
5. Remove the interface entry conduit landing plates to drill or punch holes (see Figure 31).
6. Reinstall the interface entry plates and install the conduit.
NOTE Do not directly connect relay contacts to the mains related circuits. Reinforced insulation
to the mains is required.
7. To locate the appropriate terminals and review the wiring and termination requirements, see paragraph
3.2.5 UPS System Interface Wiring Preparation, Table 21, and Figure 37 through Figure 40.
8. Route and connect the wiring.
9. If wiring TB1 battery interface connections, proceed to paragraph 4.9.2 TB1 Battery Interface Connections;
if wiring the X-Slot connections only, proceed to paragraph 4.9.3 X-Slot Connections; otherwise, proceed
to Step 10.
10. Reinstall the top internal safety shield panel and secure with the retained hardware.
11. Reinstall the front door removed in Step 3 and secure with the retained hardware.
12. Close the door and secure the latch.
