8.1.3
Electromagnetic compatibility
Definition
Electromagnetic compatibility (EMC) is the ability of an electrical installation to function
satisfactorily in its electromagnetic environment without interfering with that environment.
Among other things, the PN/MF Coupler also meets the requirements of the EMC legislation
for the European single market. The prerequisite for this is that the PN/MF Coupler complies
with the requirements and guidelines relating to electrical configuration.
Pulse-shaped interference
The table below shows the electromagnetic compatibility of the described components with
regard to pulse-shaped interference. This requires that the system comply with the
requirements and guidelines for electrical assembly.
