Installation guidelines
The installation guidelines contain information about the interference free
deployment of System 300S systems. There is the description of the ways,
interference may occur in y our control, how you can m ake sure the
electromagnetic digestibility (EMC), and how you manage the isolation.
Electromagnetic digestibility (EMC) means the ability of an electrical device,
to function error free in an electromagnetic environment without being
interferenced res. without interferencing the environment.
All System 300S com ponents are developed for the deployment in hard
industrial environments and fulfill high demands on the EMC. Nevertheless
you should project an EMC planning before installing the components and
take conceivable interference causes into account.
Electromagnetic interferences may interfere your control via different ways:
•
Fields
•
I/O signal conductors
•
Bus system
•
Current supply
•
Protected earth conductor
Depending on t he spreading medium (lead bound or lead free) and the
distance to the interference cause, interferences to your control occur by
means of different coupling mechanisms.
One differs:
•
galvanic coupling
•
capacitive coupling
•
inductive coupling
•
radiant coupling
