Installing the WBT using the integrated
brackets
The EA440 WBT is normally positioned in a dedicated room in the vicinity of the
transducer. The physical length of the cables limit the physical distance between each
transducer and the WBT. The WBT can be installed vertically or horizontally using the
integrated mounting brackets. Four bolts are used, two on each side.
Prerequisites
A suitable location for the WBT must be defined prior
to installation. We recommend that it is mounted as
close to the transducers as possible. The unit can in
principle be mounted anywhere on board the ship,
provided that the location is dry and ventilated.
The length of the transducer cables limits where the
WBT can be installed.
The unit can be mounted in any direction and on any surface provided that the
environmental requirements are met.
Note
If you mount the WBT on a bulkhead, position the unit so that all the connections are
facing down.
Procedure
1
Place the WBT in the selected position.
2
Secure the unit using 6.5 mm bolts through the two mounting brackets.
Make sure the cable connections are facing down if the unit is installed on a
bulkhead or wall.
3

Installing the EA440 hardware units
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. If a cable is damaged, and penetrated by water, the transducer
will be damaged beyond repair.
Procedure
1
Based on the vessel drawings, the physical properties of the decks and bulkheads,
and the physical locations of the transceiver 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 size of the transceiver plug and the minimum
cable bending radius into consideration.
2
Manufacture the steel conduit according to the relevant production standards.
3
Mount the steel conduit.
Secure the steel conduit to decks and/or bulkheads with welds. Observe relevant
requirements and guidelines from the classification society, and make sure that the
conduit is properly supported, strong and watertight.
Note
The quality of the welding is critical to the safety of the vessel. Welding must only
be done by a certified welder.
4
If relevant, allow the relevant maritime authority and/or classification society to
inspect and approve the design and the installation of the steel conduit.
Installing the transducer(s)
The installation of the transducer (or transducers) is a key task for successful installation
of the EA440 Single beam hydrographic echo sounder. Not only will you need to
penetrate the vessel’s hull, you must also to select a physical location for maximum
performance and minimum acoustic and electric noise.

page 27
Connecting one or more transducers to the WBT
Depending on your operational requirements for the EA440, one or more transducers
must be connected to the WBT.
Prerequisites
It is strongly recommended to lay a steel conduit from the cable gland above the
transducer to the EA440 transceiver, and to pull the transducer cable through this conduit.
There are several reasons for this.
• It will make it easier at a later stage to replace the transducer.
• It will protect the cables.
• Noise and interference from other electrical equipment is greatly reduced.
• The risk of flooding is greatly reduced when the steel conduit is terminated above
the water line.
With a steel conduit the installation will satisfy the European Union regulations for
electromagnetic compatibility (EMC) interference. Without a steel conduit, there is a
risk of reduced EA440 performance.
Context
The WBT used by the Kongsberg EA440 can be set up to work with maximum four -4operational frequencies. This means that you can use four single frequency/single beam
transducers or two dual frequency transducers.
The transducer is connected to a terminal block under a panel plate on the rear of the
WBT. The connectors are a part of the WBT delivery.

Connecting power and ground to the WBT
The EA440 WBT is powered by a dedicated power supply connected to the AC mains,
or from a suitable battery for DC operation. The unit must be properly grounded.
Context
The power for the WBT is provided by a separate power supply. It is normally connected
to an uninterruptible power supply, and will automatically detect the mains voltage (230
or 115 VAC) when connected. The output from the power supply is connected to the
+12 VDC input socket on the WBT. The AC and DC power cables are provided with
the power supply.
Procedure
1
Connect the DC cable from the power supply to the +12 Vdc socket.
If you wish to operate your WBT from a DC supply, you can use any suitable
battery providing +12 to +15 Vdc.
2
Connect the AC mains plug on the power supply to the bulkhead power outlet (or
an uninterrupted power supply).

Hydrographic Operator Station
The Hydrographic Operator Station is connected to the WBT using a high speed Ethernet
cable.
Context
Note
It is very important that a high
quality Ethernet cable is used. You
must use CAT-5E STP (Shielded
Twisted Pair) quality or better. Using
cables with lower bandwidth capacity
will reduce the EA440 performance.
Procedure:
• Connect the Ethernet cable from the Hydrographic Operator Station to the Ethernet
socket on the WBT.
• If you have a system with more than one WBT you need a switch.
Tip
We recommend having the switch in the sonar room, close to the WBTs. This gives you
only one Ethernet cable from the sonar room to the Hydrographic Operator Station.

The cable screen must be terminated in the cable gland
If you need to splice the transducer cable, we strongly recommend the use of a metal
junction box with proper cable glands. The cable screen must be connected to the cable
glands. The cable screen and the junction box chassis must not be connected to vessel
ground. Avoid ground loops. You must use the same type of cable as the original
transducer cable, contact Kongsberg Maritime for advice.

The Auxiliary socket can be used to interface
an external synchronization system (for example
K-Sync). This is beneficial when multiple
hydroacoustic systems are employed on the same
vessel.
