Emission of radio interference
The table below shows the emission values of electromagnetic interference conforming to
55011:2009, limit value 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
Note
Before you connect the HMI device to the public power grid, ensure that it is compliant with
Limit Class B in accordance with EN 55022:2006.
