If your UPS is configured with parallel function, up to 3 UPS can be connected
in parallel for power parallel or N+1 redundancy.
In parallel system, the mechanical installation for each modular is same as the
single system. Details please refer to Chapter 3.3.
Parallel system AC cable diagram:
4.1 Wiring for AC/DC cable
1. Wiring length requirement:
When the distance between the load and the parallel UPS is less than 10
meters, the length difference between the input/output lines between the
UPSs in the parallel system is less than 20%.
When the distance between the load and the parallel UPS is greater than 20
meters, the length difference between the input/output lines between the
UPSs in the parallel system is less than 5%.
2. Professional installation is required, please set the parallel system in the
restricted area!
This chapter introduces how to wire AC IN/OUT cable to UPS in parallel
system, and UPS connecting with EBM/MBP.
