Note
Malfunctions caused by EMC interference
The purpose of shielding cables is to attenuate (dampen) magnetic, electrical or
electromagnetic interferen
ce fields. Connect the cable shield of the fieldbus cable to system
ground with low impedance to that interference currents on the cable shield can b
e
conducted to ground.
Generally follow the instructions in the EMC Guide (
http://www.siemens.com/emc-guideline)
and implement the measures stated in it for shielding the cables and for connecting the
shield.
