Use of Ferrite on drive output terminals:
To comply with the most stringent standard for radiated
emissions (EN 55011 cl. B) a ferrite must be installed at the
output terminals of the drive as shown in Illustration 3.8.
The motor phase wires (T1, T2, T3) must be wound twice
around the ferrite, while the PE wire is directly connected
to the chassis, see Illustration 3.8.
