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 disconnected. See Chapter 17: “UPS
operating instructions” for shutdown instructions.
2. Unfasten the front door latch and swing the door open (see Figure 4-1 on page 31).
3. 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 and TB2 and the left interface entry conduit landing plates, remove the screws
securing the top protective cover panel and remove the panel. Retain the hardware for later use
(see Figure 4-5 on page 37).
5. Remove the interface entry conduit landing plates to drill or punch holes (see Figure 4-4 on
page 36).
6. Reinstall the entry plates and install the conduit.

Do not directly connect relay contacts to the mains related circuits. Reinforced insulation to the
mains is required.
