EMC
Electromagnetic compatibility (EMC) describes the ability of electronic and electrical devices or systems
to work properly in the electromagnetic environment and not to generate electromagnetic interference that
inuences other local devices or systems.
In other words, EMC includes two aspects: The electromagnetic interference generated by a device or
system must be restricted within a certain limit; the device or system must have sufficient immunity to the
electromagnetic interference in the environment.

domestic purposes
■
Second environment
Environment that includes all establishments other than those directly connected to a low-voltage power
supply network which supplies buildings used for domestic purposes
