3.4.4 Underground installations
The remote sensor is protected by IP68/ NEMA 6P and can be positioned underground. We recommend the use
of gravel for at least 300mm (12 inches) around the sensor. This provides drainage and prevents dirt solidification
on the sensor. In addition, it facilitates the location of the same if new excavations are required. Before covering
the gravel with earth, we recommend using electrical cable identification tape above the gravel itself. The remote
sensor cable should pass through a plastic conduit.
