5. Locate the 1G1, 1G2, 2G1, 2G2, 3G1, and 3G2 power wiring harnesses. Route these harnesses through
the wiring access in the right side panel of the ISBM section to the AC Input to UPMs terminals. See
Figure 4-8 for terminal locations.
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 3-18), connect phase A, B,
and C cable lug connections to the AC Input to UPMs terminals. Follow the callout details in Figure 4-9 to
connect the correct cable lug to the proper terminals. See paragraph 3.2.3 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 for terminal
locations.
9. Using hardware from the intercabinet wiring terminal hardware kit (see Table 3-18), connect the positive
and negative cable lug connections to the DC Input to UPMs terminals. Follow the callout details in
Figure 4-10 to connect the correct cable lug to the proper terminals. See paragraph 3.2.3 for wiring and
termination requirements.
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 for terminal locations.
11. Using hardware from the intercabinet wiring terminal hardware kit (see Table 3-18), connect phase A, B,
and C cable lug connections to the AC Output from UPMs terminals. Follow the callout details in
Figure 4-11 to connect the correct cable lug to the proper terminals. See paragraph 3.2.3 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 four UPM model and secure the hardware (see Figure 4-9). This hardware is
used by an Eaton Customer Service Engineer to install a Field Installed UPM (FI-UPM).
13. Locate the ground braid in the bottom left front corner of the UPM section. The ground braid is secured at
the factory to the UPM section ground bolt. Route the ground braid through the wiring access in the right
side panel of the ISBM section to the ground bolt in the ISBM section.
14. Connect the ground braid to the ISBM section ground bolt and secure.
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.
NOTE When connecting the UPM battery cables, verify the cables are connected to the
correct terminals.
NOTE AC output intercabinet power wiring harnesses are supplied attached to the interior
left side panel of the UPM section (see Figure 4-5).
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.
NOTE Four intercabinet interface wiring harnesses are supplied coiled inside the
protective cage on the right side panel of the ISBM section (see A in Figure 4-12).
