Notes:
If screened cable is used to connect sensor, then GND A terminal may be used to
connect the screen. But it is more recommended to connect screen to functional ground or
e.g. metal cabinet ground (PE).
For precision temperature measurements the proper cold junction temperature
measurement have to be considered. The device during typical operation heats up about
10
°C, what has influence on the device terminals temperature. It should be considered to
move the wiring compensation cables to extra terminals in the cabinet with stable
temperature. The cold junction temperature should be measured with external temperature
sensor (e.g. Pt100) at the external terminals then.
