Ferrite Rings - KEB Combivert R6 Instruction Manual

Technical Data

3.4.1 Ferrite rings

Ferrite rings are used for the reduction of the cable-based and radiated interferences. For a
high damping, the ferrite rings are attached as close as possible to the interference source,
i.e. at the DC and at the motor output terminals of the frequency inverter. The conductors must
passed through the ferrite core for the use as current-compensated choke. PE must be passed
outside. Further information can be taken from the provided documentation. Which ferrite ring
shall be used is dependent on the used cable cross-section.
