1.
The wiring of parallel port of each mode UPS is the same, in above figure, we take 30kVA as an
example to illustrate.
2.
The UPS parallel system requires the user to distribute power by himself.
1. The wiring and phase sequence of each unit in the parallel system must be the same
strictly, which is to ensure the bypass power of parallel system is the same phase.
2. The parallel system of this series UPS can share battery groups, but the battery amount
of each UPS must be the same.
3. Connect the parallel ports of each unit in parallel by equipped shielding communication
wire. The two RJ45 parallel ports are the same, they are redundancies and backup for
each other to increase the reliability of the system, once one of them is not connected,
the UPS will send alarm prompting.
