The potential equalization line (brown) must only be connected if it has to be assumed
that the measurement device and measurement liquid are not on the same earthing
potential.
In this case, an additional electrical link to the measurement liquid is provided for potential
equalization and the sensor-side potential equalization line is to be applied there.
