Note: The output wiring requirement as below:
1) If the distance between the UPS and breaker panel is less than
20 meters in parallel system, the length difference between
input and output cable of the UPSs is required to be less than
20%.
2) If the distance between the UPS and breaker panel is more than
20 meters in parallel system, the length difference between
input and output cable of the UPSs is required to be less than
