4.9 Installing Interface Connections
WARNING
Hazardous voltages are present near the user interface terminal area if the UPS is not totally
disconnected.
Use the procedures in the following paragraphs to connect the TB1, TB1 Battery, TB2, and TB3 interface
connections.
4.9.1 TB1, TB2, and TB3 Connections (Other than 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 7, “UPS Operating
Instructions” for shutdown instructions.
2. If not already opened, unfasten the front door latch and swing the door open (see Figure 4-1).
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 4-24).
5. Remove the interface entry conduit landing plates to drill or punch holes (see Figure 4-19).
6. Reinstall the interface entry plates and install the conduit.
WARNING
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 3.2.4, Table 4-1,
and Figure 4-24 through Figure 4-27.
8. Route and connect the wiring.
9. If wiring TB1 battery interface connections, proceed to paragraph 4.9.2; if wiring the X-Slot connections
only, proceed to paragraph 4.9.3; otherwise, proceed to Step 10.
10. Reinstall the small top internal safety shield panel and secure with the cabinet mounted screws.
11. Reinstall the front door removed in Step 6 and secure with the retained hardware.
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.
