Installing 3.3 Terminal blocks Terminal blocks Terminal strips behind the upper front door Different reference potentials: The terminals labelled "GND" are connected internally. "GND" and "GND IN" are not connected internally. Figure 3-1 Interconnection example of the digital inputs with external 24 V power supply Interconnecting the analog inputs (terminals 3, 4 and 10, 11) For the analog inputs, you may use the internal 10 V supply (example: terminals 1 …...
