Cable Splicing - Simrad TRANSDUCER - INSTALLATION GENERIC REV H Installation Manual

Simrad Echo sounder transducers

Cable splicing

36
If you need to cut or lengthen the transducer cable, you must
splice it correctly. The cable between the junction box and the
transceiver must then be supplied by Simrad, and this must be
the same type as used on the transducer(s).
Note
Do not solder the wires together with only electrical tape for
insulation, as this will result in electrical noise and reduced
operational performance.
To splice the cable, use a metal junction box with EMC cable
glands and a terminal block. The terminal block must provide
solid fastening of the cable ends as well as sufficient insulation
between the wires.
Note
We recommend that the cable screen is connected to the junction
box chassis using the EMC cable glands, but if you do this, the
junction box chassis must not be connected to ship's ground.
The cable screen must not be connected to the ship's ground
through the junction box.
