Basic procedures
4.1.1 Cable ducts
In order to avoid highfrequency thermal radiation, power connections
from the switching cabinet to the motor should be laid in completely en
closed metal cable ducts.
In the case of multichamber cable ducts, encoder cable should also be
laid in a separate chamber in the cable duct.
The cable duct is connected over a large area with machine parts and the
switch cabinet.
