2.1 Wiring Outline
Connect the power cable, transducer cables, sensor cable, network cable and ground wire to their
respective locations on the network sounder. See the next page for how to connect the transducer
cables.
Ground
Connect a ground wire (IV-2 sq, local supply) between the
ground terminal and ship’s ground to prevent interference
to the sounder picture. Make the length of the wire as short
as possible. For FRP vessels, install a ground plate that
measures about 20 cm by 30 cm on the outside of the hull
bottom and connect the ground wire there.
