Figure 3. Wiring Harness Adapter P-152001881
The total battery string voltage in a 9355 20-30 kVA UPS is 216V (18 batteries, where is each battery is 12V
nominal). The single-tray configuration that is being replaced holds 18 batteries. Two strings fit in each battery
shelf of the 9355 20-30 kVA UPS. The single-tray red connector is the most positive connection while the black
is the negative connection. The white connector presents the middle point in the single-tray configuration,
where 108V is measured from the white to the red and 108V from the white to the black. The white connector
is used for CSE testing only.
The replacement tray sets contain nine batteries each, such that it takes two trays to complete one string.
Each P-106000220 kit includes two single-row battery trays and two harness adapters. Only one harness
adapter is needed for the installation; the second harness adapter is a spare.
