battery disconnect. See Figure 4-18, Figure 4-20, Figure 4-25, and Figure 4-26 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 3-10 on
page 3−14), 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 4-25 as needed. See paragraph 3.2.2
