Electromagnetic compatibility

Pulse-shaped interference
The following table shows the electromagnetic compatibility of modules with regard to pulse-
shaped interference. This requires the device to meet the specifications and directives for
electrical installation.
Pulse-shaped
interference
Electrostatic
discharge
in accordance with
IEC 61000-4-2
Bursts
(high-speed transient
interference)
in accordance with
IEC 61000-4-4
Powerful single pulse (surge) according to IEC 61000-4-5, external protective circuit is required (see
function manual "SIMATIC S7-1500, ET 200MP, ET 200SP, ET 200AL Designing interference-free
controllers", section 7 "Lightning protection and overvoltage protection") on the Internet
(https://support.industry.siemens.com/cs/ww/en/view/59193566).
