19. 

Now actuate the mains input miniature circuit breakers 
(no. 2,  p. 27/28) on each UPS one after the other. Move 
them to the "ON" position. 

20.  Move the “maintenance switch” manual bypass 

switches (no. 3, p. 27/28) on the back of each UPS 
to the “UPS” position. Finally, fasten the covers on 
each UPS again using the 4 respective screws that 
were previously removed.

The voltage supply of the parallel operation 
busbar now takes place via the integrated 
electronic bypass switches of the UPS systems 
used. Check this operating state on the display 
panel of each UPS = Bypass (chapter 6.1.3). 

21.  Now actuate your central external manual bypass: 

Switch from the “Bypass” position to “UPS operation”, 
i.e. connect your load busbar to the UPS parallel 
operation busbar.

This is done using a manual bypass switch with 
overlapping switching contacts without any 
interruption in the load voltage, i.e. completely 
interruption-free. 

22. 

Now switch on the inverters of the UPS systems. To 
do this, press the ON pushbutton of each UPS for 
approx. 2 seconds one after the other.

After switching on, each UPS carries out a self-
test and synchronizes itself with the parallel 
operation busbar, while the LED’s for load and 
battery state switch on and off consecutively in 
increasing order. After the successful 
synchronization of all inverters, the Inverter LED 
on each UPS lights up a few seconds later, 
whereby the UPS systems now work in parallel 
normal operating mode and supply the parallel 
operation / load busbar with UPS voltage. 

 

The central external manual bypass switch must 
be protected against accidental actuation. Never 
actuate it when the UPS systems are in inverter 
mode.
