3.9 UPS Multi－Module Installation
The basic installation procedure of a parallel system comprising of two or more
PowerGem Plus RT UPS modules is the same as that of single module system. The
following sections introduce the installation procedures specified to the parallel system.
3.9.1 Cabinet installation
Connect all the UPS systems needed to be put into parallel system as below picture.
Ensure that each UPS input breaker is in the off position and all external output breakers
are OFF so that there is no output from each UPS connected. Battery groups can be
connected separately or in parallel, which means the system itself provides both separate
battery and common battery function
WARNING!
Make sure the N、L lines are correct, and grounding is well
connected.
