Electromagnetic compatibility
The HMI device satisfies, among other things, the requirements of the EMC guidelines of the
European domestic market.
EMC-compatible installation of the HMI device
The EMC-compliant installation of the HMI device and the application of interference-proof
cable is the basis for interference-free operation.
