Simrad ES333-7CD
TRANSDUCER CABLE SPLICING
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). 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. 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 vessel’s ground.
Note
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.
