Technical specifications
7.2 Directives and declarations
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
HF radiation (in
electromagnetic fields)
IEC 61000-4-3
RF interference current
on cables and cable
shielding
IEC 61000-4-6
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
230 to 1000 MHz
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.
