Screening
The screening of the data and signal lines reduces the electromagnetic influences
and thus increases the signal quality. Measurement errors, data transmission
errors, and even destruction due to excessive voltage can be prevented this way.
Data and signal lines must be laid separately from all high-voltage cables.
There must be large-area contact between the screening of the cables and the
ground potential. The screening should be laid at the entrance to the cabinet or
housing in order to catch interference right at the entrance.
The screening of the bus line is described in the respective configuration
guidelines and standards of the bus system (RS485 specification).
Lay the screening so that its area is as large as possible!
Improved screening is achieved if the large-area screening is applied. This is
especially recommended for systems with a large circumference where the
possible occurrence of equalizing current or high impulse-type currents caused by
atmospheric discharge cannot be avoided. The WAGO-I/O-SYSTEM is suitable
for the screening connection system.
