UPS Parallel Installation
The following sections introduce the installation procedures specific to a parallel system.
3.10.1
Cabinet installation
Connect all the UPS needed in the parallel system as below.
Make sure each UPS input breaker is in the “off” position and there is no output from any of the UPS.
Battery groups can be connected separately or in parallel, which means the system can be either a
separate battery or a common battery.
WARNING!
Make certain the N, A (L1), B (L2), C (L3) lines are correct and grounding is well
secured.
3.10.2
Parallel cable installation
The shielded and double insulated control cables must be interconnected in a ring configuration
between UPS units as shown below. The ring configuration ensures high reliability of the control.
