WEEE label (European Union)
Disposal instructions, observe the local regulations and the section "Recycling and disposal
(Page 32)".
5.3 Electromagnetic compatibility
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
