2.5 Electromagnetic compatibility
The HMI device fulfils, among other things, the requirements of the EMC laws pertaining to
the European domestic market.
EMC-compliant installation of HMI devices
An EMC-compliant installation of the HMI device and the use of interference-proof cables
form the basis of trouble-free operation. The following documentation applies to the
mounting of the HMI device:
● Description "Directives for interference-free installation of PLCs"
(http://support.automation.siemens.
com
/WW/view/de/1064706)"
● The manual "PROFINET System Description"
Pulseshaped Interference
The following table shows the electromagnetic compatibility of modules compared to pulse-
shaped interference. These specifications only apply when the HMI device meets the
specifications and directives regarding electrical installation.
