7.2 Electromagnetic Compatibility, Shipping and 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.
