Installation summary
Installation of the EA640 system is a demanding task that requires careful preparations, a
number of specific procedures, wiring and required system settings.
Context
An overall installation procedure is provided.
Note
In order to obtain maximum safety and optimal performance, it is very important that the
installation procedures in this manual are complied to. You must do the tasks in the order
they are described. The vessel owner must make sure that the installation shipyard holds
the applicable competence to perform the installation, and that the applicable maritime
authorities are available to verify and certify the installation.
Procedure
1
Determine the physical location of the transducer (or transducers).
Necessary considerations must be taken to avoid acoustic and electric disturbances.
2
Install each transducer.
Each transducer will penetrate the hull. For this reason, this is a crucial part
of the installation. 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 EA640 system 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.
3
Install the EA640 system units.
Note that some EA640 system units may be commercial. Unless ordered specifically
these are not included in the delivery, and must be purchased locally.
4
Install the cables between the EA640 system units.
Observe the relevant cable plan, procedures, as well as the general requirements for
cabling.
5
Turn on the EA640 system for the first time, and set it to work.

In order to turn on the EA640 system in a safe and correct manner, the relevant
procedures must be complied to!
