How to attach connector to transducer cable
Note: For dual-frequency transducer, use the optional cable assy. NCS255AD-254P-L500.
Ground
To prevent interference to the picture and radio equipment, connect a ground wire (KIV 2.0
sq, black) between the ground terminal and ship’s grounding bus. The length of the wire
should be as short as possible.
To obtain a good ground on an FRP vessel, a 20 × 30 cm copper plate can be welded on
the outside of the ship’s hull. Connect the ground wire to the copper plate.
Note: Use a "closed-type" lug (
) to make the connection at the network sounder. Do
not use an "open-type" lug (
).
Ground the equipment to
prevent mutual interference.
