Eaton Power Xpert 9395 UPS Installation and Operation Manual 164201725—Rev 15 61
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 12), connect phase A, B, and
C cable lug connections to the AC Input to UPMs terminals. Follow the callout details in Figure 32 for
common rectifier feed with CSS to connect the correct cable lug to the proper terminals. See paragraph
3.2.4 UPS System Power Wiring Preparation for wiring and termination requirements.
NOTE The 3G3 red and black battery input intercabinet power wiring harnesses are not
supplied with the Power Xpert 9395-825/550 Two UPM UPS model.
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 31 for common
rectifier feed with CSS 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 12), connect the positive and
negative cable lug connections to the DC Input to UPMs terminals. Follow the callout details in Figure 33
to connect the correct cable lug to the proper terminals. See paragraph
3.2.4 UPS System Power Wiring Preparation 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 28).
NOTE The 3G4 and 3G4 yellow, orange, brown, and gray AC output intercabinet power wiring
harnesses are not supplied with the Power Xpert 9395-825/550 Two UPM UPS model.
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 cablesto the AC Output from UPMs terminals. See
Figure 31 for common rectifier feed with CSS 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 12), connect phase A, B, and
C and Neutral cable lug connections to the AC Output from UPMs terminals. Follow the callout details in
Figure 34 to connect the correct cable lug to the proper terminals. See paragraph
3.2.4 UPS System Power Wiring Preparation 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 32 for common rectifier
feed with CSS). This hardware is for future use if a Field Installed UPM (FI-UPM) is installed to upgrade the
UPS to a Plus 1 model.
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.
