7.4  Measurement transducer: Magnetostrictive sensor with 

 4-wire transmitter (option ..T..) 

  Ensure that the electrical power supply is deenergised. 

  To avoid disturbances from electric fields of other electrical circuits, the cable 

should not be laid together with other high voltage cables. 

  Remove the cover and run the power supply cable through the cable gland. 

  Connect the transmitter as shown in the following wiring diagram.
