8.3. Parallel Function
Brief introduction of the redundancy
：
N+X is currently the most reliable power supply structure. N represents the
minimum UPS number that the total load needs, X represents the redundant UPS
number, i.e. the fault UPS number that the system can handle simultaneously.
When the X is larger, the reliability of the power system is higher. For occasions
where reliability is highly depended on, N+X is the optimal mode.
As long as the UPS is equipped with parallel cables, up to 4 UPS can be connected
in parallel to realize output power sharing and power redundancy.
How to install a new parallel UPS system:
1) Before installing a new parallel UPS system, user need to prepare input and
output wires, input and output breaker, main maintenance bypass switch.
2) Remove the cover plate of the parallel port on the UPS, connect each UPS
one by one with the parallel cable, and re-screw the parallel port cover which is
supplied in the accessories.

3) Strictly follow the chapter of 6.1, the wiring requirement of single UPS to
perform the wiring of each UPS.
