The UPSs in parallel connection must be assigned the same parallel group
ID No. in order to let the outputs of the parallel UPSs be put in parallel
connection and let the loads be evenly distributed among the parallel units.
If the parallel UPSs have different parallel group ID No., their output signals
might be synchronized but their outputs cannot be connected in parallel.
The UPSs that need to be paralleled must be assigned the same parallel
group ID No. and different parallel ID No. in order to let the parallel function
work.
If the parallel UPSs that have the same parallel group ID No. need to share
common batteries, please select 'Enable' for the 'Common Battery' setup
item. Otherwise, the function of battery abnormality detection will fail.
