NOTE Two cable lugs will be connected to each terminal stud. When connecting the cable lugs, install the
first lug on the stud with the raised barrel portion facing the back of the cabinet. Install the second lug with
the raised barrel portion facing the front of the cabinet.
6. Locate the intercabinet wiring terminal hardware kit packed on the bottom right
side of the ISBM section.
7. Using hardware from the intercabinet wiring terminal hardware kit (see Table 3-8
on page 3−12), connect phase A, B, and C cable lug connections to the AC Input
to UPMs terminals. Follow the callout details in Figure 4-9 on page 4−12 for
commom rectifier feed or Figure 4-11 on page 4−14 for separate rectifier feed to
connect the correct cable lug to the proper terminals. See paragraph 3.2.2 on
page 3−8 for wiring and termination requirements.
8. Locate the 1G3, 2G3, and 3G3 power wiring harnesses. Route these harnesses
through the wiring access in the right side panel of the ISBM section to the DC
Input to UPMs terminals. See Figure 4-8 on page 4−11 for common rectifier feed
terminal locations or Figure 4-10 on page 4−13 for separate rectifier feed terminal
locations.
NOTE When connecting the UPM battery cables, verify the cables are connected to the correct terminals .
9. Using hardware from the intercabinet wiring terminal hardware kit (see
Table 3-8), connect the positive and negative cable lug connections to the DC
Input to UPMs terminals. Follow the callout details in Figure 4-12 on page 4−15 to
connect the correct cable lug to the proper terminals. See paragraph 3.2.2 on
page 3−8 for wiring and termination requirements.
NOTE AC output intercabinet power wiring harnesses are supplied attached to the interior left side panel
of the UPM section (see Figure 4-5 on page 4−6).
10. Locate the 1G4, 1G5, 2G4, 2G5, 3G4, and 3G5 power wiring harnesses. Remove
the front two columns of wire ties securing the cables to facilitate routing cables
to the AC Output from UPMs terminals. See Figure 4-8 on page 4−11 for
common rectifier feed terminal locations or Figure 4-10 on page 4−13 for separate
rectifier feed terminal locations.
NOTE Two cable lugs will be connected to each terminal stud. When connecting the cable lugs, install the
first lug on the stud with the raised barrel portion facing the back of the cabinet. Install the second lug with
the raised barrel portion facing the front of the cabinet.
11. Using hardware from the intercabinet wiring terminal hardware kit (see
Table 3-8), connect phase A, B, and C and Neutral cable lug connections to the
AC Output from UPMs terminals. Follow the callout details in Figure 4-13 on
page 4−15 to connect the correct cable lug to the proper terminals. See
paragraph 3.2.2 on page 3−8 for wiring and termination requirements.
12. Install the remaining hardware (three washers, conical washers, and nuts) onto
the AC Input to UPMs terminals designated for the Plus 1 model and secure the
hardware (see Figure 4-9 on page 4−12 for common rectifier feed or Figure 4-23
on page 4−26 for separate rectifier feed). This hardware is for future use if a Field
Installed UPM (FI−UPM) is installed to upgrade the UPS to a Plus 1 model.
