Parallel UPS connection 

 
IMPORTANT NOTE: 

Parallel system installation is much more complex from stand alone UPS installation, it 

needs qualified sevice personnel.

 

 
You have to keep 80 cm distance between two UPS for service purposes. The maximum length of digital and 
analog cable is 2 meters. 
 
Add %20 tolerant to cables, fuses and circuit breakers in parallel connection. 
 
At figure 3-2 ,the connections of 2 parallel UPS and load switch panel is shown.
