Note
The two "+" and "M" terminals are jumpered in the connector and not in the device. This
ensures that the supply voltage is looped through.
The current consumption increases by the current consumption of DRIVE-CLiQ and the
digital outputs.
When using external power supplies (e.g. SITOP), the ground potential must be connected
with the protective ground terminal (PELV).
