Chapter: 4. Installation
Transducer Junction Box
The standard cable tted on the transducer is 25 m or 40 m and may be shortened. The junction box is used
to interconnect the transducers xed cable to a yard supply extension cable if the total required cable length
is longer than the standard cable. In tank installations, it is required to run the standard cable in a steel
protecting pipe from the tank to the highest water level. Special requirements apply in areas with explosive
conditions. The junction box must always be mounted outside such areas.
Interconnect the transducer pair and its screen in the junction box, but do not ground the screen here.
