Wiring in Accordance with EMC Regulations
The quality of the shield is dependent on the quality of the connection of the
screen. In principle, the best screening action can only be achieved with the
connection of the shield at both ends with large area connections.
If it is not possible to connect the screen via threaded fittings, connect the
screen physically close, for example, to a control cabinet chassis with a metal
clamp.
IMPORTANT If there is a PE in an installation, it can be used for the connection of the
functional earth connection (FE). However, an FE is never allowed to be used
as a PE.
Functional Earth
To achieve the specified EMC safety, the functional earth FE must be
connected (for example, to the central earth star point of the vehicle or system).
