Splicing the transducer cable
If you need to extend the transducer cable, you must splice it correctly. This is very
important, as any splice is very vulnerable for noise.
Cable can be spliced using two different methods:
• Splicing using a grounded junction box
• Splicing using a junction box that is isolated from vessel’s ground
The following items are required.
• A metal junction box with cable glands designed for electromagnetic
compatibility (EMC). The junction box must contain a suitable terminal block. The
terminal block must provide solid fastening of the cable ends as well as sufficient
insulation between the wires.
• The necessary length of transducer cable.
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.
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.
You must be equipped with a standard set of tools. This tool set must comprise the
normal tools for electronic and electromechanical tasks. This includes different
screwdriver types, pliers, spanners, a cable stripper, a soldering iron, etc. Each tool
must be provided in various sizes. We recommend that all tools are demagnetized to
protect your equipment.
Note
Do not solder the wires together using only electrical tape for insulation. This will result
in electrical noise and reduced operational performance.
