Note
The two "+" or "M" terminals are jumpered in the connector. This ensures that the supply
voltage is looped through.
The current consumption increases by the value for the DRIVE-CLiQ node. The digital
outputs are supplied via terminals X520, X521, and X522.

1
least one DI/O of the potential group is used as an output.
M1: A ground reference for DI/O 0 to 7 (first potential group) must always be connected if at
least one DI/O of the potential group is used as either an input or an output.
