2. WIRING
Connect the power cable and transducer cable as shown below. See the next page
for how to fabricate the transducer cable.
2.1 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 (approx. 20 cm by 30 cm)
on the outside of the hull bottom and connect the ground wire there.
