Context
The installation shipyard must provide all
necessary design and installation drawings,
as well as the relevant work standards
and mounting procedures. If required, all
documents provided by the shipyard for
the physical installation of the EC150-3C
must be approved by the vessel’s national
registry and corresponding maritime
authority and/or classification society.
Such approval must be obtained before
the installation can begin. The shipowner
and shipyard doing the installation are
responsible for obtaining and paying for such approval.
Important
Finalize the steel conduit installation before you pull the transducer cable through it.
Make sure that there are no spatter, sharp edges or protruding objects that can damage
the transducer cables.
The outline dimensions of the EC150-3C transducer and the relevant installation items
can be found in the
Drawing file chapter in this manual. End user manuals and source
drawings (normally in AutoCad format) can be downloaded from our website.

Procedure
1 Based on the vessel drawings, the physical properties of the decks and bulkheads,
and the physical locations of the power supply unit and the transducer, design the
steel conduit.
The steel conduit must preferably be straight. Start the conduit immediately
above the transducer, and terminate it well above the water line. If you must
introduce bends on the steel conduit, take the minimum cable bending radius into
consideration.
