Safety instructions and approvals
2.4 Electromagnetic compatibility
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.
Sinusoidal interference
Test values
HF radiation (in
electromagnetic fields) in
accordance with
IEC 61000-4-3
80% amplitude modulation at 1 kHz
RF interference current on
cables and cable shielding
conforming to IEC 61000-4-6
Degree of severity
•
Up to 10 V/m in the 1 to 2 GHz range
•
Up to 3 V/m in the 1.4 to 2 GHz range
•
Up to 3 V/m in the 2 to 2.7 GHz range
Test voltage 10 V, with 80% amplitude modulation
of 1 kHz in the 10 kHz to 80 MHz range

Emission of radio interference
The following table shows the unwanted emissions from electromagnetic fields in
accordance with EN 55011, Limit Value Class A, Group 1, measured at a distance of 10 m.
Frequency
Interference emission
30 to 230 MHz
< 40 dB (μV/m) quasi-peak
230 to 1 000 MHz
< 47 dB (μV/m) quasi-peak
1 to 3 GHz
•
66 dB (mV/m) peak
•
46 dB (mV/m) average value
•
70 dB (mV/m) peak
•
50 dB (mV/m) average value
3 to 6 GHz
Additional measures
If you want to connect an HMI device to the public power supply system, you must ensure
Limit Value Class B in accordance with EN 55022.
Interference emission for mains AC power supply
The following table below shows the interference emission for mains AC power supply.
Frequency
Interference emission
0.15 to 0.5 MHz
•
< 79 dB (µV) quasi-peak
•
< 66 dB (µV) average value
•
< 73 dB (µV) quasi-peak
•
< 60 dB (µV) average value
0.5 to 30 MHz
