3.5 Parallel Installation
The 3C3 PRO Series support parallel installation. The parallel connection wires
(optional) can be used to connect 2 to 4 UPS units in parallel to achieve power
redundancy (N+X). The minimum clearance between two UPS units is 10cm. The
input wiring requirements for paralleled UPS units are the same with those for
single unit. The input/output of paralleled UPS units should all be connected to
the same input/output patch board, from which wires are distributed for load as
illustrated in the following figure:

Output Patch Board
NOTE:
1. Paralleled UPS units can share the battery packs for 20-80kVA; The batteries
of each battery pack should be batteries of the same type and from the same
batch produced by the same manufacturer;
2. Requirements for output wire length:
①
When the wires connecting the input (output) terminals of paralleled UPS
units with the input (output) patch board are shorter than 20m, the difference
in wire length should be smaller than 20% of the length
②
When the wires connecting the input (output) terminals of paralleled UPS
units to the input (output) patch board are longer than 20m, the difference
should be smaller than 10%.
