Paralleling UPS Devices

General

A maximum 3 devices of the following ratings can be connected in parallel:
- Linear Plus, 6 kVA and 10 kVA
- Linear Plus RM, 6 kVA and 10 kVA
The units to be connected in parallel must be of the same type and rating.
Further the settings - if available - of these devices must be identical.
Only Linear Plus, 6 kVA and 10 kVA: check settings of all parallel units. Table
10 on page EN-40 shows setup parameters (main menu 5). The settings of
output voltage must be the same.
Designing a parallel system
When connecting mains and loads to a parallel UPS Linear Plus/ RM system
additional distribution has to be taken into account.
A system of 2 parallel UPS blocks can be connected directly to the
distribution if the system load doesn't exceed the nominal power of the
UPS block (configuration: half load, 2 block parallel system)
If the systems load is greater, an external maintenance bypass has to be
installed (Recommendation of a parallel configuration please see Fig. 25 on
page EN-56).
Linear Plus 6 kVA and 10 kVA configured as parallel system may use only
common mains supply (means: put in jumper between input terminals
mains 1 and reserve (mains 2).
