Cable in steel conduit
It is strongly recommended to lay a steel conduit from the
transducer to the echo sounder transceiver, and draw the
transducer cable through the conduit. There are two reasons for
this procedure.
• First, it will make it easier at a later stage to replace the
transducer.
• Second, noise and interference from other electrical
equipment is greatly reduced.
With a steel conduit the installation satisfies the EU regulations
for EMC interference. Without a steel conduit, there is a risk of
reduced echo sounder performance.
