Splicing The Transducer Cable - Simrad ES38-18 Installation Manual

Simrad ES38-18/200–18C Installation manual
Important
Ensure that the surface of the transducer face, the hull plating and putty around the
transducer is as even and smooth as possible. Obstructions on these surfaces will create
problems with turbulent flow.
6 If required, allow the relevant maritime authority and/or classification society to inspect
and approve the installation.

Splicing the transducer cable

If you need to cut or lengthen the transducer cable, you must splice it correctly.
Prerequisites
Electrical installations can only be done by certified electricians. All necessary tools and
instruments required must be available. The installation shipyard must prepare detailed
drawings of the electrical system, and identify each cable.
Observe the basic cable requirements.
The cable between the junction box and the transceiver must be supplied by Kongsberg
Maritime, and this must be the same type as used on the transducer(s).
You will also need a metal junction box with cable glands designed for electromagnetic
compatibility (EMC), and a terminal block. The terminal block must provide solid fastening
of the cable ends as well as sufficient insulation between the wires.
Context
Do not solder the wires together with only electrical tape for insulation. This will result in
electrical noise and reduced operational performance.
Do not connect the cable screen to the vessel's ground.
