7.2 Electromagnetic compatibility, shipping an d storage
conditions
Definition
Electromagnetic compatibility is the capability of an electrical device to function
satisfactorily in its electromagnetic environment without interfering with this
environment.
The ET 200S distributed I/O system also meets the requirements of the European
Union’s EMC legislation. A requirement for this is that the ET 200S distributed I/O
system meets the specifications and directives concerning electrical installation.
Pulse-shaped interference
