Read and understand the following information in addition to the information in paragraph
3.2.2 IAC-D Power Wiring Preparation while planning and performing a system installation with a single-feed
UPS and a Sidecar Integrated Accessory Cabinet-Bypass (SIAC-B) or wall mount maintenance bypass:
NOTE The 208V/208V IAC-D can be used only with a three-breaker SIAC-B or wall mount
maintenance bypass.
• The SIAC-B maintenance bypass input (E6,E7,E8) or wall mount maintenance bypass input must be fed
from the output of the 208V/480V IAC-D input autotransformer for single-feed systems when using a
three-breaker bypass. This must be a 480V feed.
• The 480V output of the UPS (E9, E10, and E11) is wired to the SIAC-B or wall mount maintenance bypass
MIS input.
• The 480V output from the SIAC-B (E9, E10, and E11) or wall mount maintenance bypass is wired to the
480V input of IAC-D.
For external input power wiring recommendations, including the minimum AWG size of external wiring, see
Table 4 for 480V/208V IAC-D and Table 5 for 208V/208V IAC-D. Wire sizes listed are for copper wiring only.
