- A device can be disturbed by interference fields arising in the environment, and operation of the device can at the same time itself produce interference which affects its environment.
This applies both to industrial applications and to appliances used in the home.
The basic demands made on devices with regard to electromagnetic compatibility (EMC) are thus:
- Attainment of a defined interference immunity (protection against external interference fields)
- Prevention / reduction of emitted interference (protection for the environment against own interference fields)
-
Possible sources or subjects of electromagnetic disturbance are:
- Mains connection cables
- Signal and control cables
- Electrical of electronic modules which emit electromagnetic fields or which can themselves be disturbed by such fields
-
However, a typical metal housing already offers electrical devices significant protection against electromagnetic interference fields.
In practical applications, it has been proven that, in more than 95 per cent of all applications, a standard Rittal enclosure or housing offers sufficient shielding to guarantee electromagnetic compatibility.
