Remark: The EARTH signal is connected internally to the metal case and to all SHIELD signals.
It is completely insulated from all electric signals of IDMx40. This feature may facilitate avoiding
ground loops. It is recommended that Earth be connected to GND at only one point, preferably
close to the V supply output.
