2.3 Matching Box/Junction Box
Mounting Considerations
The matching box/junction box forms a joint between the hull unit and the transceiver
unit.
Use the matching box for CI-35, junction box for CI-35H.
Install it referring to the guidelines below.
1) Keep the box away from noise emitting electrical machinery, i.e., electric generator,
radio transmitter, TV, etc.
2) Do not install it in places of high humidity.
3) Avoid installing the box where temperature varies greatly, since moisture may
penetrate the box.
4) The box is generally installed above the draft line of the ship and the transducer
cable is run inside steel conduit. This permits replacement of the transducer
without dry docking. Even if the junction box is installed below the draft line, the
conduit is necessary to minimize picking up of noise. If use of conduit is not possible,
install the box as near to the transducer as possible.
