UPS SYSTEM INSTALLATION

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 3-8on 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 4-9on page 4−12 for commom rectifier feed or Figure 4-11on 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 4-8on page 4−11 for common rectifier feed terminal locations or Figure 4-10on 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 4-12on 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 4-5on 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 4-8on page 4−11 for common rectifier feed terminal locations or Figure 4-10on 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 4-13on 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 4-9on page 4−12 for common rectifier feed or Figure 4-23on 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.
