9.3 Electromagnetic compatibility, transport and storage conditions
Definition of EMC
Electromagnetic compatibility is the ability of electrical equipment to function satisfactorily in
its electromagnetic environment without influencing this environment.
The ET 200iSP distributed I/O device also meets the requirements of the EMC law of the European
market. This requires that the ET 200iSP distributed I/O device meets the specifications and
directives for electrical installation.
EMC in accordance with NE21
The ET 200iSP distributed I/O system complies with the EMC requirements of NEMUR directive
NE21.
