7.
Route the input and output cables to the UPS terminal blocks. See Drawing
164201603-7 starting on page A-36 for wiring access information and terminal
locations.
8.
If wiring a single-feed system, proceed to Step 9; if wiring a dual-feed system,
proceed to Step 11.
9.
Connect phase A, B, C, and Neutral (if required) input power wiring from the
utility source to the bypass input terminals and neutral terminals in the UPS
cabinet. See Appendix A for wiring and termination requirements and wiring
access information. Note wiring connections for single-feed systems.
11. Disconnect the single-feed jumpers from phase A, B, and C terminals on rectifier
input terminals and bypass input terminals. Remove the jumpers from the
cabinet.
12. Connect phase A, B, and C rectifier input power wiring from the utility source to
the rectifier input terminals in the UPS cabinet. See Appendix A for wiring and
termination requirements and wiring access information. Note wiring
connections for dual-feed systems.
13. Connect phase A, B, and C, and Neutral (if required) bypass input power wiring
from the utility source to the bypass input terminals and neutral terminals in the
UPS cabinet. See Appendix A for wiring and termination requirements and wiring
access information. Note wiring connections for dual-feed systems.
14. If wiring an IDC or IAC, proceed to Step 15; otherwise, proceed to Step 18.
15. Route and connect the output cable between the UPS cabinet and the IDC or
IAC. Refer to the applicable IDC or IAC installation and operation manual,
referenced in paragraph 1.5 on page 1-6, for wiring instructions. See Appendix A
for UPS cabinet wiring access information.
16. Connect phase A, B, and C, and Neutral (if required) power wiring from the IDC
or IAC to the UPS cabinet output and neutral terminals. See Appendix A for
wiring and termination requirements.
18. If wiring a parallel system, proceed to Step 19; otherwise, proceed to Step 21.

Parallel system wiring length should be in accordance with Drawing 164201603-5 , sheet 23 of 23, to ensure
approximately equal current sharing when in static bypass mode.
19. Connect phase A, B, and C, and Neutral (if required) power wiring from the
output and neutral terminals of each uninterruptible power module (UPM) to the
module tie cabinet. See Appendix A for UPM wiring and termination
requirements and wiring access information.
21. Connect phase A, B, and C, and Neutral (if required) power wiring from the
output and neutral terminals to the critical load. See Appendix A for wiring and
termination requirements and wiring access information.
