EMC-Considerations
In industrial environment, the grounding and shielding of the cables and devices is
very important for safe operation.
Cable shields should be connected on both ends of the cable to a low impedance
drain. Devices should be grounded properly at their ground connections. If this is
disobeyed, the shielding and protection methods of the devices will not work cor-
rectly and the device might radiate electromagnetical interfering signals.
