3.1 Shielded Cables
To guarantee trouble-free operation, we recommend the use of shielded cables.
Operation, however, is also possible with unshielded cables. Data transfer problems must be examined on a
case-by-case basis. Where necessary, a shielded cable must be used for the corresponding devices.
The design frame is protected by a transparent foil. Please remove this foil prior to
installation.
