M2: Ground reference
B = Bidirectional; I = Input; GND = Reference potential (ground)

Note
An open input is interpreted as "low".
To enable the digital inputs to work, terminal M1 or M2 must be connected. The following
alternatives are available:
● Connect the carried digital input reference ground to M1 or M2.
● Insert a bridge between terminals M and M1 (or between M and M2).
