Digital signal / bus lines and analogue signal / sensor lines should be laid in separate cables It is advisable to use shielded cables for analogue signal lines.● The shield should be earthed at the entry or exit to the switching cabinet. The shields should be as short as possible and of the largest possible cross-section. The central earthing point should be > 10 mm² and connected to the PE ground● The shield should be earthed at the entry or exit to the switching cabinet. The shields should be as short as possible and of the largest possible cross-section. The central earthing point should be > 10 mm² and connected to the PE groundwire by the shortest route ● The shield is generally connected to one side of the switching cabinet only, unless there is a potential equalization with significantly lower resistance than the shield resistance Inductivities installed in the same switching cabinet, e.g. contactor coils, should be provided with suitable suppressors (RC elements)
