Because the physical transmission media is more robust, the bipolar connection should always be used. The unipolar
connection should only be used if the encoder type does not output push-pull signals.
WARNING
Danger to life through electric shock due to unconnected cable shields
Hazardous touch voltages can occur through capacitive cross-coupling due to unconnected
cable shields.
• Attach the cable shield to the component for the encoder system connection at th
