EDSTCXX EN 2.0

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.
