Caution!

 

 

 

The frequency inverters meet the requirements of the low-voltage directive 2006/95/EC and the 
requirements of the EMC directive 2004/108/EC. The EMC product standard EN 61800-3 relates to 
the drive system. The documentation provides information on how the applicable standards can be 
complied if the frequency inverter is a component of the drive system. The declaration of conformity is 
to be issued by the supplier of the drive system. 

 
 

4.1.1  KFU 210 (up to 3,0 kW) and 410 (up to 4,0 kW) 

Mains connection, X1 

1

 With a mains current above 10 A, the mains power connection 230 V 1ph/N/PE and the mains power 

connection 230 V 2ph/N/PE are to be done on two terminals. 
 
Motor connection 

For connection of the ground conductor of the mains and motor cable, use the provided terminal connection 
options X1 and X2. Other connection options for connecting the mains and motor cable are not permissible. 
For connection of a braking resistor, use terminals R

b1

 and R

b2
