/ ST350EX, the cable must be inserted in the
proper manner. (See chapter 2.2 - Cable requirements and Cable installation). The signal cable
must be connected to the power supply and the signal output of the sensing head. These are
available on connector CON2 (see wiring diagram).
In a REMOTE application, an extra connection cable has to be connected to connector CON1 and
the connections found in the junction box of the sensor (see wiring diagram).
