Sinusoidal interference
The following table shows the EMC behavior of the modules with respect to sinusoidal
interference. This requires the HMI device to meet the specifications and directives for
electrical installation.

Emission of radio interference
The following table shows the emitted interference from electromagnetic fields in accordance
with EN 55011, Limit Class A, Group 1, measured at a distance of 10 m.
30 to 230 MHz
< 40 dB (V/m) quasi-peak
230 to 1000 MHz
< 47 dB (V/m) quasi-peak
Additional measures
Before you connect an HMI device to the public network, ensure that it is compliant with Limit
Value Class B in accordance with EN 55022.
