4.
Route the AC utility source input wiring (phase A, B, and C, and Ground) through the conduit and the wire
tray (Figure 4-8 or Figure 4-9) on the back of the ITC to the ITC AC input to transformer terminals. See
Figure 4-10 or Figure 4-13 for ITC terminal locations. See paragraph 3.2.2, Table 3-4, and Table 3-5 for ITC
wiring and termination requirements.
5.
Connect phase A, B, C, and ground ITC input power wiring from the utility source to the ITC AC input to
transformer terminals and ground terminals. See paragraph 3.2.2 for wiring and termination requirements.
6.
If installing wiring using conduit, continue to Step 7; if using the power terminal cover base channels, skip
to Step 15.
7.
Punch or drill holes in the bottom of the power terminal cover base on the UPS cabinet for the UPS
rectifier input conduit. Refer to the applicable Eaton 93E UPS Installation and Operation manual listed in
paragraph 1.6 for UPS cabinet conduit landing location.
8.
Install conduit between the UPS cabinet and the ITC.
9.
Route the UPS rectifier input wiring (phase A, B, and C, Neutral and Ground) from the ITC through the wire
tray and the conduit to the UPS terminal block on the back of the UPS. See Figure 4-10 or Figure 4-13 for
ITC terminal locations. See paragraph 3.2.2, Table 3-4, and Table 3-5 for ITC wiring and termination
requirements. Refer to the applicable Eaton 93E UPS Installation and Operation manual listed in paragraph
1.6 for their respective terminal locations and termination requirements.
10. Connect phase A, B, C, Neutral, and Ground rectifier input power wiring from the ITC to the UPS rectifier
input, neutral, and ground terminals. See paragraph 3.2.2 for wiring and termination requirements.
11. Connect phase A, B, C, Neutral, and Ground ITC output power wiring to the ITC AC output to UPS, neutral,
and ground terminals. See paragraph 3.2.2 for wiring and termination requirements.
12. Install the power terminal cover top using the provided hardware (see Figure 4-17).
13. Install the power terminal cover right and left sides using the provided hardware (see Figure 4-17).
14. Skip to Step 22.
15. Route the UPS rectifier input wiring (phase A, B, and C, Neutral and Ground) from the ITC through the wire
tray and the power terminal cover base wiring channels (see Figure 4-16) on the back of the ITC to the
UPS terminal block on the back of the UPS. See Figure 4-10 or Figure 4-13 for ITC terminal locations. See
paragraph 3.2.2, Table 3-4, and Table 3-5 for ITC wiring and termination requirements. Refer to the
applicable Eaton 93E UPS Installation and Operation manual listed in paragraph 1.6 for their respective
terminal locations and termination requirements.
16. Connect phase A, B, C, Neutral, and Ground rectifier input power wiring from the ITC to the UPS rectifier
input, neutral, and ground terminals. See paragraph 3.2.2 for wiring and termination requirements.
17. Connect phase A, B, C, Neutral, and Ground ITC output power wiring to the ITC AC output to UPS, neutral,
and ground terminals. See paragraph 3.2.2 for wiring and termination requirements.
18. Secure the power cables to the power terminal cover base using wire ties after all electrical connections
have been completed.
19. Install the power terminal cover tops using the provided hardware (see Figure 4-18).
20. Install the ITC left side power terminal cover and the UPS right side power terminal cover using the
provided hardware (see Figure 4-18).
21. Install the splice cover using the provided hardware (see Figure 4-18).
22. Reinstall the internal safety shield panel removed in Step 2.
23. Close the outside door and secure the latch.
24. After the ITC is installed and wired, return to the applicable Eaton 93E UPS Installation and Operation
manual listed in paragraph 1.6 to complete the UPS wiring.
