The use of supplied cable clamps
If the CE marking requirements for cables are mandatory, the mains input cable and the motor cable
used must all be shielded type of cables. In that case, you can use the cable clamps as a ground
connection between the cable shielding layer and a common ground point.
Clamps can also be helpful in better fixing cables (the unshielded motor cable and the mains input
cable) in place.
The illustration below shows you how to use the clamps to fix both cables and to make a shielding
connection with the cable.

Caution
Note
Make sure that the clamp for fixing the shielded motor cable is in close contact
with the shielding layer of the cable.
After the installation, it is recommended that the screws on the terminal covers
should be screwed down to ensure the safety.
Installation
Siemens does not provide the shielded motor cable. Please prepare the shielded
motor cable by yourselves for CE certification.
