Basic rules for the EMC-equitable assembly of installations
The term electromagnetic compatibility (EMC) refers to the ability of an
electrical device to operate properly in an electromagnetic environment
without interference from the environment or without the device causing
illegal interference to the environment.
The Operation Panels are developed for applications in harsh industrial
environments and complies with EMC requirements to a large degree. In
spite of this you should implement an EMC strategy before installing any
components, which should include any possible source of interference.
Electromagnetic interference can enter your system in many different ways:
Fields
Bus
Power
PE
I/O-Signal
Automation
System
Interference is coupled into your system in different ways, depending in the
propagation medium (conducted or not conducted) and the distance to the
interference source.
We differentiate between:
•
galvanic coupling
•
capacitate coupling
•
inductive coupling
•
radiated power coupling
