ƒ Only use cables with braided shields.
ƒ The cover density of the shield should exceed 80%.
ƒ For data cables for the serial coupling always use metallic or metallised
connectors. Attach the shield of the data cable to the connector
housing.
ƒ Use metal cable clamps to attach the braided shields.
ƒ Connect the shield to the shield rail in the switch cabinet.
ƒ Connect shields of analogue control cables on one side only (either at
the sensor or as near as possible to the input of the analogue module).
ƒ Earth all metallic conducting components using suitable cables from a
central earthing point (PE rail).
ƒ Observe the minimum cross−sections defined in the safety instructions:
– For EMC it is not the cable cross−section which matters, but the
surface of the cable and the contact area.
