Electromagnetic compatibility
The HMI device, docking station, power supply and RFID tag meet the requirements of the
EMC regulations pertaining to the European domestic market and more. The enhanced
testing and limit value levels defined by CDV 61326-3-1/Ed. 1 have been taken into account
during the type test
EMC-compliant installation
Conditions for fault-free operation include EMC-conform assembly of the docking station and
RFID tag, as well as the use of interference-proof cables. The following documents also
apply to the installation of the docking station:
● Description "Directives for interference-free installation of PLCs"
(http://support.automation.siemens.com/WW/view/de/1064706), German
● System manual "Basics on Setting up an Industrial Wireless LAN"
(http://support.automation.siemens.com/WW/view/en/9975764)
Pulse-shaped disturbance
The following table shows the electromagnetic compatibility of modules with regard to pulse-
shaped interference. The table applies to the docking station, with and without an attached
HMI device.
