Contacting the shielding on the motor
Connect the shielding on the motor side to the PE junction that is located directly on the motor
housing.
For prefabricated motor lines from ZIEHL-ABEGG SE, the shielding connection is provided with a ring
cable eye for the corresponding thread size.
When using non-prefabricated lines, implement the shielding connection by using a suitable shielding
connection system.

Cable length
The maximum line length is 25 m.
When lines over > 25 m are used, compliance with
DIN EN 12015
(electromagnetic compatibility
–
electrical interference) and
DIN EN 12016
(electromagnetic compatibility
–
noise immunity) is no
longer guaranteed.
On the ZAdyn4C MRL Bx, the shielding of the motor line must be connected with earth potential with
the clip provided (see
