NOTE
The 3G1 and 3G2 yellow, orange, and brown AC input intercabinet power wiring harnesses are not
supplied with the Eaton 9395-825/550 Two UPM UPS model.
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 4‐10 on page 4-14 for
common rectifier feed with Momentary Static Switch (MSS) terminal locations,
Figure 4‐12 on page 4-16 for common rectifier feed with Continuous Static
Switch (CSS) terminal locations, or Figure 4‐14 on page 4-18 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.
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 3‐10 on page 3-19), connect phase A, B, and C cable lug connections to the
AC Input to UPMs terminals. Follow the callout details in Figure 4‐11 on page
4-15 for common rectifier feed with MSS, Figure 4‐13 on page 4-17 for common
rectifier feed with CSS, or Figure 4‐15 on page 4-19 for separate rectifier feed to
connect the correct cable lug to the proper terminals. See paragraph 3.2.2 on
page 3-11 for wiring and termination requirements.
NOTE
The 3G3 red and black battery input intercabinet power wiring harnesses are not supplied with the
Eaton 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 4‐10 on page 4-14 for common rectifier feed
with MSS terminal locations, Figure 4‐12 on page 4-16 for common rectifier feed
with CSS terminal locations, or Figure 4‐14 on page 4-18 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 3‐10), connect the positive and negative cable lug connections to the DC
Input to UPMs terminals. Follow the callout details in Figure 4‐16 on page 4-20 to
connect the correct cable lug to the proper terminals. See paragraph 3.2.2 on
page 3-11 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 4‐7 on page 4-8).
