4.4 Ground connection
4.4.1 05M, 1M, 2M, 3M models
At the bottom side of the mainboard PCB you will find a connector (jumper) which has been placed from
factory side as shown in the picture [
bottom and middle pin connected]. In this position the ground
connections (GND power supply/ outputs) are connected with the ground of the electronics housing.
To avoid ground loops and related signal interferences in industrial environments it might be necessary to
interrupt this connection. To do this put the jumper in the opposite position [
middle and top pin connected].
If the thermocouple output is used the connection GND
– housing should be interrupted generally.
