8.
If installing wiring using conduit, continue to Step 9; if using the power terminal cover base channels, skip
to Step 30.
9.
Punch or drill holes in the bottom of the power terminal cover base on the UPS cabinet for the UPS
rectifier and bypass input conduits. Refer to the applicable Eaton 93E UPS Installation and Operation
manual listed in paragraph 1.6 for UPS cabinet conduit landing location.
10. Install conduits between the UPS cabinet and ITC1 and ITC2.
11. Route the UPS rectifier and bypass input wiring (phase A, B, and C, Neutral and Ground) from ITC1 and
ITC2 through the wire tray and the conduit to the UPS terminal blocks 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.
12. Connect phase A, B, C, Neutral, and Ground rectifier input power wiring from ITC1 to the UPS rectifier
input, neutral, and ground terminals. See paragraph 3.2.2 for wiring and termination requirements.
13. Connect phase A, B, C, Neutral, and Ground ITC1output power wiring to the ITC1 AC output to UPS,
neutral, and ground terminals. See paragraph 3.2.2 for wiring and termination requirements.
14. Connect phase A, B, C, Neutral, and Ground bypass input power wiring from the ITC2 to the UPS bypass
input, neutral, and ground terminals. See paragraph 3.2.2 for wiring and termination requirements.
15. Connect phase A, B, C, Neutral, and Ground ITC2 output power wiring to the ITC2 AC output to UPS,
neutral, and ground terminals. See paragraph 3.2.2 for wiring and termination requirements.
16. Route the UPS output wiring (phase A, B, and C and Ground) from ITC1 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.
17. Connect phase A, B, C and Ground UPS output power wiring from the ITC1 to the UPS output and ground
terminals. See paragraph 3.2.2 for wiring and termination requirements.
18. Connect phase A, B, C and Ground ITC1 output power wiring to the ITC1 AC output to UPS and ground
terminals. See paragraph 3.2.2 for wiring and termination requirements.
19. Install conduit between ITC1 and the critical load or Integrated Accessory Cabinet-Bypass (IAC-D). Refer
to the
Eaton 93E Integrated Accessory Cabinet-Distribution Installation Manual
listed in paragraph 1.6 for
conduit and terminal locations and termination requirements.
20. Route the critical load output wiring (phase A, B, and C, Neutral and Ground) through the wire tray and the
conduit on the back of ITC1 to the ITC1 AC output to critical load 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.
21. Connect phase A, B, C, Neutral, and Ground output power wiring from the critical load or IAC-D to the
ITC1 AC output to critical load, neutral, and ground terminals. See paragraph 3.2.2 for wiring and
termination requirements.
22. Install the power terminal cover top using the provided hardware (see Figure 4-17).
23. Install the power terminal cover right and left sides using the provided hardware (see Figure 4-17).
24. Skip to Step 43.
25. Route the UPS rectifier and bypass input wiring (phase A, B, and C, Neutral and Ground) from ITC1 and
ITC2 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.
