3BHARDWARE CONFIGURATION AND INSTALLATION
Only use cables with mesh shielding. The cover density of the shield should be at
least 80%.
To attach the mesh shielding, only use metal cable clips. The clips must envelop
the shield extensively and make good contact.
The shield clamps must be ordered separately to the shield connection element.
The size of the shield clamp is to be chosen according to the cable diameter.
To attach a cable with the shield clamp, approx. 1.5 cm of the cable insulation is to
be cut out of the place which is to be laid. The bare shield is then to be pressed
tight against the shield connection element with the shield clamp.
The following figure shows the mounting of the shield clamps:

The shield should be pressed against the shield rail by means of the shield clamp.
