Figure 4-12 through Figure 4-17 for wiring access information and terminal locations.
2. If wiring the UPS for a common battery, proceed to Step 3; if wiring for a separate battery, proceed to
Step 5.
3. Using hardware from the external wiring terminal hardware kit (see Table 3-18), connect the positive,
negative, and ground DC power wiring from the battery system or disconnect to the ISBM section battery
and ground terminals. Use both sets of terminals shown in Figure 4-17 as needed. See paragraph 3.2.5 for
wiring and termination requirements.
4. Proceed to Step 6.
5. Using hardware from the external wiring terminal hardware kit (see Table 3-18), connect the positive,
negative, and ground DC power wiring from the battery systems or disconnects to the ISBM section
battery and ground terminals. Use one set of terminals for each UPM. See paragraph 3.2.5 for wiring and
termination requirements.
6. After wiring the UPS system to the facility power and critical load, be sure to ground the system according
to local and/or national electrical wiring codes.
7 . If wiring interface connections, proceed to paragraph 4.9; otherwise, proceed to Step 8.
8. When all wiring is complete, reinstall the top and bottom safety shield panels removed in paragraph 4.8.2,
Step 2. Secure with the retained hardware.
9. Reinstall the left front panel removed in paragraph 4.8.2, Step 1 and secure with the retained hardware.
