Grounding Concepts
Functional ground is a low impedance current path between electrical circuits and ground. It is used, for example, to
improve immunity to disturbances, but is not a protective measure. Grounding deflects disturbances, but does not neces-
sarily provide protection against electric shock.
The functional ground on the processor has two connections:
•
Supply voltage GND terminal
•
Grounding connection on the processor back panel
To guarantee a good functional ground:
•
Connect the processor to the central grounding point in the control cabinet using the shortest route possible.
•
Use a cable with a minimum cross section of 2.5 mm² per connection. If a cable with wire tip sleeves is connected
to the supplied power plug, then a cable with maximum 1.5 mm² per connection is possible.
•
Use shielded cable for all data connections.
