1. Brief introduction
As long as the UPS is equipped with parallel cables, up to 3 UPSs can be connected
in parallel to realize output power sharing and power redundancy.

two standard 15-pin communication cables which length is
appropriate to be less than 3m.
2) Strictly follow the stand-alone wiring requirement to perform the input wiring of
each UPS.
3) Connect the output wires of each UPS to an output breaker panel.
4) Each UPS need an independent battery pack.

UPSs is required to be less than 20%.
●
When the distance between the UPSs in parallel and the breaker panel is
