When are grounding and EMC solutions used?
Grounding and EMC solutions are used in industrial installations where electrical and electronic systems need to be protected against interference and potential differences. They are particularly important in automation systems, machines and control cabinets with frequency converters, control systems and communications.
A correct grounding and EMC structure contributes to stable operation, personal safety and compliance with applicable standards.
When are simpler solutions sufficient?
Not all installations require advanced EMC solutions. In simpler applications with low noise levels and limited electronics, basic grounding may be sufficient.
- Simpler solutions may be sufficient when:
- the installation contains few sources of interference
- signal and power levels are low
- no sensitive communication systems are used
- surrounding environment is electromagnetically uncritical
However, in more complex systems, the requirements for structured grounding and EMC components increase.
Various solutions in grounding and EMC
Grounding bars
Grounding bars are used to collect protective earth and create clear grounding points in control cabinets and electrical installations.
Cable Clamps
Shield clamps are used to connect cable shields to ground and reduce electromagnetic interference in signal and power cables.
EMC cable entry
EMC cable glands are used when cable shields need to be effectively connected to the enclosure to achieve good EMC performance.
Earthing braids and earthing straps
Earthing braids are used for potential equalization between different parts of the installation where flexible connection is required.
Important requirements and common pitfalls
Incorrect or inadequate grounding is a common cause of EMC problems in industrial installations.
Common pitfalls:
- unclear or too long ground connections
- poor contact between cable shield and enclosure
- multiple ground points without a well-thought-out structure
- grounding that is not adapted to the frequency content of the installation
A well-thought-out grounding strategy should be developed early in the project.

FAQ – Frequently asked questions about grounding and EMC solutions
Why is grounding important for EMC?
Proper grounding reduces the risk of electromagnetic interference by creating controlled return paths for interference currents
When are EMC components needed in addition to basic grounding?
In installations with sensitive electronics, high frequencies or a strong interference environment, supplementary EMC components are often required.
Does cabling affect EMC performance?
Yes, cabling, separation of signal and power, and correct shield connection have a major impact on EMC properties.
