Failure to observe this may result in destruction of parts of the electronics. ► When installing Ex-approved devices in a hazardous area please take special note of the instructions and connection schematics in the respective Ex documentation added to these Operating Instructions.

  • Page 14: Connecting The Sensor Cables

    Wiring Connecting the sensor cables When connecting 2 sensors ensure that there is no galvanic connection between the sen- sors (e.g. caused by sensor elements that are not isolated from the thermowell). The result- ing equalizing currents distort the measurements considerably. In this situation, the sensors have to be galvanically isolated from one another by connecting each sensor separately to a transmitter.
