2 Installation
• The installation includes 6 major steps:
1. Read the installation and operation manual.
2. Plan where to install the WSI-box, transducers and instruments.
3. Run the cables.
4. Install the WSI-box, transducers and instruments.
5. Learn the functions and calibrate your system.
Before you begin drilling ... think about how you can make the installation as neat
and simple as your boat will allow. Plan where to position the transducers, Server
and instruments. Think about leaving space for additional instruments in the future.
•A few ”do not” you should consider:
−Do not cut the cables too short. Allow extra cable length at the Server so it
can be disconnected for inspection without having to disconnect all
attached cables.
−Do not place sealant behind the display. The instrument gasket eliminates
the need for sealant.
−Do not run cables in the bilge, where water can appear.
−Do not run cables close to fluorescent light sources, engine or radio
transmitting equipment to avoid electrical disturbances.
−Do not rush, take your time. A neat installation is easy to do.
• The following material is needed:
Wire cutters and strippers.
Small and large Philips and small flat head screw driver.
Hole saw for the instrument clearance of 63 mm (2½").
Hole saw for the transducer of 51 mm.
2.8mm drill for the WSI-box mounting screws
5 mm (1/4") drill for the mounting holes.
Plastic cable ties
If you are doubtful about the installation, obtain the services of an experienced
technician.

2.1 Installing the instrument
•Place the adhesive drill template on the desired location for the instrument. Drill the
2 holes using a 5 mm (1/4") drill for the two pin bolts. Use a 63 mm (2½") hole saw
to machine the clearance hole for the instrument connection socket. Remove the
template.
•Screw the two pin bolts to the instrument
•Put the instrument in place
•Screw the two nuts from the back
Note! The two nuts must just be tighten by hand only
•Run the Nexus Network cable from the WSI-
box to the instrument.
•If you want to cut the Nexus Network cable to
length, disconnect 4-pole jack plug and cut
the cable. Peel off about 35 mm (1.4") of the
cable insulation. Remove about 6 mm (1/4")
from the 3 isolated wires (the 4th wire is an
earth / screen). Attach the 4 cable protectors
to the wires using a pair of flat pliers.
•Connect the 4 cable protectors to the 4-pole
jack plug as shown. Apply silicon paste on all
locations as shown.
Note: Must be done to avoid corrosion.

2.2 Installing the WSI-box
Remove the WSI-box cover from the base plate by removing the
screw. Drill the 3 screw holes using a 2.8 mm (0.11") drill. Mount
the WSI-box using the 3 mounting screws.
Apply silicon paste on the screw terminal. Connect the 8 m Nexus
Network cable supplied with cable protectors to the WSI-box on
pins 13, 14, 15, and 16. Match the colour codes for each wire.
2.3 Installing the Wind Transducer
2.3.1IMPORTANT Installation information!
BEFORE placing the wind transducer on the mast, a pairing
procedure must be done!
2.3.2Location
The transducer should be mounted on a horizontal surface in the mast head. If the
masthead is not horizontal a shim has to be added. A 15 shim for Seldén masts is
available (art.no 67400-15).
2.3.3Mounting in the mast head
The transducer permits any type of horizontal mounting angle.
Mount the unit by directing the pipe (1) down and backwards in the bracket (2). Secure
the nut (3) towards the attachment BY HAND (tools can be needed when demounting).
Attach the security clamp (4) behind the nut.
