Note
The connection cables are to be shielded if longer than 30 m.
For every connector there is one pin for connecting or looping through the 24 V supply
voltage and the 0 V. All 24 V and GND pins of both connectors are connected to each other,
making it possible to loop through the supply voltage (daisy chain), while taking the
maximum current into account.
