When connecting the motor cable, the enclosed split ferrite (grey, Würth number: 742
727 22) must be placed around the three wires (T1/T2/T3).
For variant -A (2, 2 kW), the wires T1/T2/T3 must be routed twice trough the split ferrite.
In the C- and F-Version (4 und 5 kW) the wires must be routed one time through the split
ferrite.
We recommend to place another split ferrite (black, Würth number: 74271722S) as
close as possible to the door controller around the complete motor cable. The black split
ferrite is not included in the scope of delivery!
