EMC and grounding measures
The ground connection of all relevant components must be executed with the largest possible cross-section, with a low impedance, over a large area and via a short connection to a conductive fastener with a large area. The shields have to be applied with a sufficiently large contact area on both sides.
Grounding measures are essential to ensure effective electromagnetic compatibility (EMC). The following points should be observed:
- ►Connect all grounding points directly to the central grounding bar or mounting plate.
- ►Ensure that the connections have low resistance and good conductivity.
- ►Use the shortest possible connections.
- ►Design the connections to the grounding bar in a star configuration.
- ►Ensure that the connections are protected against corrosion.
- ►Use flexible ground straps for moving parts such as machine parts or doors. These straps should be as short and large as possible.
