5.2 Motor and brake connections
Connect the shielding of the motor cable to the EMC bracket (for steel housings)!
Connect the shielding of the motor cable to the PE terminal.
For steel housings, also make direct contact between the shielding and the EMC
bracket.
To do this, remove a piece of the insulation of the motor cable and fix the shielding with
the clamp on the EMC bracket.

Figure 12: Motor connection
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).
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!
