Appendix B: 
Paralleling UPS 
Devices

Larger loads may be supported with 12, 16, and 20 kVA Sinergy SE II kits, created by paralleling two 6, 
8, or 10 kVA SE II units respectively. By adding a third UPS, a parallel-redundant system is created.

General information for paralleling UPSs: 

• A maximum of 3 UPSs of the following ratings can be connected in parallel: 4 kVA, 6 kVA, 8 kVA, 

or 10 kVA

• The units to be connected in parallel must be of the same type. All configurable UPS parameters 

must be the same.

• On 4 kVA, 6 kVA, 8 kVA, and 10 kVA: check settings of all parallel units. The table on page 22 

shows setup parameters (setup menu 5). The settings of output voltage must be the same.

General information for designing a parallel system:

• UPSs configured as a parallel system must all be configured for single input (same source to both 

main and bypass) mode. Jumpers must be installed between JL1 & BL1 and between JL2 and BL2 
on each unit.

• When connecting mains and loads to a parallel UPS system additional distribution has to be taken 

into account.

• A system of two parallel UPS blocks can be connected directly to the distribution if the system load 

doesn’t exceed the nominal power of the UPS module (configuration: half load, two module parallel 
system)

• If the systems load is greater, another UPS must be added to provide the additional capacity.
