UPS Multi-Module Installation

3.2Paralleled UPS Modules

The basic installation procedure of a parallel system comprising two or more UPS modules is the same as that of single module system. The following sections only introduce the installation proce- dures specific to the parallel system.

3.2.1Cabinet Installation

Place the UPS modules side by side and interconnect as shown in Figure 29. The distribution panel (external bypass cabinet) is optional but recommended for ease of maintenance and system testing.
