2.8 Layout of Cabinet

Besides the UPS cabinet, there are also battery cabinets, input/output distribution cabinet and cabinet for bypass transformer. All these cabinets should be laid out correctly. The layout of battery cabinet and UPS cabinet is shown below.

1. One UPS cabinet and one battery cabinet

If the required battery backup time is 15 – 16 minutes, one battery cabinet is required to hold all the required batteries. There is no strict requirement for the relative position of the UPS and the battery cabinet. Figure 2-11 shows this kind of layout.

Capacity expansion must be considered into layout design.

2. One UPS cabinet and several battery cabinets

More than one UPS cabinet should be used if the required backup time is more than 30 minutes. Please refer to Chapter 9 for the relationship between the battery backup time and the battery capacity.

The battery cabinets should be placed side-by-side and the UPS cabinet can be placed on the left or right side, in front of or behind the battery cabinets. Be sure to leave space for maintenance.
