4.3.3 Two UPS Battery Cabinets/HA32A UPS Installation
When two UPS Battery Cabinets are required to meet the specified backup or protection
time, each should be installed according to the directions in Section 4.3.2. Except for
a common chassis ground connection, no connections should be made between the UPS
Battery Cabinets.
4.3.4 Power Cable Connections
The power cable connections should be made after selecting the appropriate size wire
that satisfies the maximum permissible cable voltage drop requirements specified in
Section 4.3.1. Make sure that the correct polarities are observed when making all dc
connections. Positive (+) to positive and negative (-) to negative.
Power cable connections and the chassis ground connection are made on the inside rear,
top right portion of the UPS Battery Cabinet (Figure 4–4).
See Figure 4–1 for the UPS Battery Cabinet power cable connections in the UPS cabinet.
See Figure 4–3 for the chassis ground connection in the UPS cabinet.
