Revision 002 User’s and Installation Guide
AC output intercabinet power wiring harnesses are supplied attached to the interior left side
panel of the UPM section (see Figure 4-1 on page 31).
10. Locate the E12/UPMx, E9/UPMx, E10/UPMx and E11/UPMx power wiring harnesses. Remove
wire ties as necessary to enable routing cables to the ISBM AC output from UPMs terminals. See
Figure 4-6 for terminal locations.
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, connect phase L1, L2 and L3
and neutral cable lug connections to the AC output from UPMs terminals. Follow the callout details
in Figure 4-9 to connect the correct cable lug to the proper terminals. See Section 3.2.2 on page 19
for wiring and termination requirements.
12. On 675-825 kVA models install remaining hardware (three washers, conical washers, and nuts)
onto the AC input to UPMs terminals designated for the systems with a Field Upgrade UPM and
secure the hardware (see Figure 4-7). This hardware is for future use if a field-installed UPM (FI-
UPM) is installed to upgrade the UPS to a system with a Field Upgrade 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.
Four intercabinet interface wiring harnesses are supplied coiled against the right side panel of
the ISBM section (see A in Figure 4-10).
15. In the ISBM section (see A in Figure 4-10), locate the long coiled wiring harnesses with the J50,
J51,J61 and J70 connectors attached. Remove the wire ties securing the harnesses and uncoil the
harnesses.
16. Locate the mating P50 connector in the UPM section wireway (see B in Figure 4-10) and connect
the P50 connector to the J50 connector.
17. Locate the mating P51 connector in the UPM section wireway (see B in Figure 4-10) and connect
the P51 connector to the J51 connector.
18. Locate the mating P61 connector in the UPM section wireway (see B in Figure 4-10) and connect
the P61 connector to the J61 connector.
19. Locate the mating P70 connector in the UPM section wireway (see B in Figure 4-10) and connect
the P70 connector to the J70 connector.
Intercabinet interface wiring harnesses are supplied coiled against the left side panel of the UPM
section (see B in Figure 4-10).
