7-8 AC Input/Output Wiring (Parallel UPS – Single Input Source)

 

Parallel UPS Warnings:

2

• The total input cable length must be equal to the total

 

output cable length in order to prevent unbalanced load

 

sharing between two UPS systems under reserve mode

 

(i.e. Res1 + OP1 = Res2 + OP2; deviation must be <10%).

 

• Parallel configuration only supports 2 UPS systems (1+1

3

redundancy or capacity). Do not attempt to link more than

 

two UPS systems via parallel configuration.

 

• The UPS systems must have the same rating and capacity

 

for parallel UPS installation. Attempting to link

4

dissimilar UPS systems will damage the UPS systems

 

and create a serious risk of personal injury and property

 

damage.

 

 

• Each UPS must have its Parallel group set to 2 and a

 

 

 

5

 

different “Parallel ID” that indicates the UPS systems are

being run in parallel. (See Section 10-5-5for more details.)
