Connection of the shield-rail for analog signals
21.4.2 Notes on wiring the analog lines
z Analog lines and reference voltage must be connected with a shielded
cable.
z The shield-rail must be connected to the GND-terminal.
z The shield must be placed on the shield rail as shown above.
z To attain optimum interference immunity, analog lines should not be laid
out parallel to strong interfering lines (e.g. lines of converters for mo-
tors).
