position „bypass” i.e. that the mains supplies the 
loads bus-bar.  

5. 

Connect the separator of the output of each UPS, 
i.e. connect every output of a UPS with the parallel 
operation bus-bar. 

6.  Put in the prefuse of the low voltage main 

distribution field (there, where the UPS systems 
are connected on the input side with the mains), 
resp. switch on the corresponding line fuse.

The load supply now takes place via the central 
external manual bypass. The parallel operation 
bus-bar is supplied by the integrated bypass of 
each UPS. Parallel operation bus-bar and load 
bus-bar are not yet connected at this time! 

7. 

Press the mains input circuit breaker one by one 
on each UPS (Pos. 3, page 26). Bring it to the 
“ON” position.  

8. 

The manual bypass switch „Maintenance Switch“ 
(Pos. 2, page 26) on the back of each UPS has to 
be brought into the “UPS” position. Fix on each 
UPS the cover with the four previously removed 
screws.

The power supply of the parallel bus-bar now is 
realised via the integrated electronic bypass 
equipment of the UPS. Check the operation 
state on the display of each UPS = bypass 
(chapter 6.1.3.).   

9. 

Activate the central external manual bypass now: 
Change from position “bypass” to “UPS operation” 
i.e. connects the load bus-bar with the UPS 
parallel operation bus-bar.

This takes place without interruption, if you are 
using a manual bypass switch with overlapping 
contacts.
