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