Technical specifications
5.3 Electromagnetic compatibility
Pulse-shaped disturbance
The following table shows the electromagnetic compatibility of modules with regard to pulse-
shaped interference. The precondition for electromagnetic compatibility is that the HMI
device meets the specifications and guidelines for electrical installation.
Pulse-shaped interference
Electrostatic discharge
in accordance with
IEC 61000-4-2
Bursts
(high-speed transient inter-
ferences)
in accordance with
IEC 61000-4-4
High-energy single pulse
(surge) in accordance with
IEC 61000-4-5

the Internet (https://support.industry.siemens.com/cs/ww/en/view/59193566).
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 (electromagnetic fields)
according to IEC 61000-4-3
HF current feed on cables and cable
shields according to IEC 61000-4-6
