Introduction

Thank you for choosing FI-30 Wind Data instrument. We are convinced that you will
appreciate all the valuable information either you are a cruiser or a racer. It is important
that you are following this instruction regarding installation and operation.

If the instrument are to be used in a Nexus Network, there are some systems settings
that are dependent on where the transducers are installed, i.e. at the instrument or at
the Server.

2 Installation

You can install the FI-30 Compass in three different ways:

• The compass transducer connected directly to the FI-30 Compass instrument

• By using the connection kit when both log and wind transducers are installed with a

single cable to the FI-30 Compass instrument.

• The installation may also include a FI-30 Server where all transducers may be

connected. All data including power will pass along one cable.

• The installation includes 6 major steps:

1. Read the operation manual.

2. Plan where to install the transducers and instruments.

3. Run the cables.

4. Install the transducers and instruments.

5. Take a break and admire your installation.

6. 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 nots” 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.
Large Philips and small flat head screw driver.
Hole saw for the instrument clearance hole 63 mm (2½").
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 pinbolts 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

• Run the Nexus Network cable from the Server 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.

Silicon paste

Note: Must be done to avoid corrosion.

• Apply silicon paste to the instrument connection pins at the back of the instrument.

Press the jack plug onto the instrument pins. Press the cable in to the cable leads.

• Mount the connection back cover with the screw.

Your instrument installation is done!

2.1.1 Installing cable

The power cable is connected via a 3A fuse from the battery or at the boats fuse panel
and direct to the instrument or Server. One red and one black power wire is included.

Note, Set C71 ON (see 5.4.1).
Always connect a 3 AMP fuse between Power supply and instrument.

2.1.2 Connections in Nexus Network

If you already have a Nexus Network i.e. a Server, it is more practical to connect the
transducer to the Server due to the single instrument cable installation. Note, Set C71
OFF (see 5.4.1).

Server

Transducer

The instrument is then connected to the Server’s Nexus Network terminal (pin 5, 6, 7
and 8) or at any FI-30 instruments terminal .
