Mount the new HV-Board with the five 

screws. 

 

 

17.

 

Mount the cables from the thermal switch  

and current transformers on the LV-Board. 

Be careful how you connect the cables 

from the current transformers (correct 

phase sequence).

Mount the cables from the thyristors and 

fans on the HV-Board. Be careful how you 

connect the cables from the thyristors.

For upgrade to Torque Control it is 

important to check the connection on the 

current transformer (see fig below). 

 

 

20.

 

If the two cables on each current 

transformer are

 black 

use a multimeter to 

detect the right connection. The resistance 

of the current transformer are between  

      0,2-6 ohm. 

 

 

21.

 

Change the position of the cables on the 

current transformers to obtain correct 

position if necessary.
