Shield support of the motor cable
Requirements for the device-side shield support of the motor cable
The type of shield support depends on the design of the motor cable. If, for example, a hybrid cable is
used to connect the motor, holding brake, and temperature sensor, the following options exist for pla-
cing the shield on the device side:
Option 1: All motor cable shields are connected over a large surface with a shield sleeve at the cable
end and placed below the shield clamp on the front side of the CMMT-AS.
