Directives and declarations

8.2.1

Electromagnetic compatibility

Introduction
The HMI device fulfills, among other things, the requirements of the EMC law pertaining to
the domestic European market.
EMC-compatible installation of the HMI device
The EMC-compliant installation of the HMI device and the application of interference-proof
cable is the basis for interference-free operation. The "Directives for interference-free
installation of PLCs" and the "PROFIBUS Networks" manual also apply for the installation of
the HMI device.
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
Burst pulses (high-speed
transient interference) in
accordance with
IEC 61000-4-4
High-energy single pulse
(surge) in accordance with
IEC 61000-4-5
