8.3
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.
Observed the following manuals in addition to these operating instructions:

Pulse-shaped disturbance
The following table shows the electromagnetic compatibility of modules with regard to pulse-
shaped interference. The precondition for electromagnetic compatibility is that the HMI
device meets the specifications and guidelines for electrical installation.
