Liebert 3000, 4000, 6000 A, 1500 Externally Mounted Battery Return Busbar, Length Width Thickness

3.4Externally Mounted Battery Return Busbar

The battery return busbar is designed to mount on the overhead racking for 6000 A systems and top cabled 1500, 3000 or 4000 A power systems. It can also be mounted on a wall or on the floor below the raised floor for bottom cabled 1500, 3000 or 4000 A power systems (which are assumed to be installed on a raised, computer type floor).

3.4.1Mechanical Specifications of the External Battery Return Busbar

The external battery return busbar kit consists of a group of single busbar laminations and attachment hardware assembled as shown in Figure 17 (6000 A shown). The kit can grow verti- cally in such a way as to maintain the 3-ft maximum radius grounding requirement. Laminations are added as required to increase the capacity. The mechanical specifications of a single lamina- tion are listed in Table 22.
