3.6.3 Parallel System
Install the battery and UPS of the parallel system, and then connect wires of parallel system.
The phase sequence of mains input must be right, or, the UPS cannot work normally.
The connection and phase sequence of AC input of each UPS in parallel system should be in
accordance with each others, and ensure the bypass power phase is the same.
Before powering, check if the input phase of each UPS is separately corresponding.
Step 1
Dismantle the bottom wiring cover plates of each UPS according to 3.6.1 Step 1.
Step 2
Connect the AC input of each UPS to mains.
Step 3
Connect the AC output of each UPS to load or distribution cabinet.
