3-2 Installation guide
This is a general guide for locating and wiring the parts of the G-PILOT 3100. The instructions for
a particular part may have additional requirements.
3-2-1 Location guide
Do not mount any part where it can be used
as a handhold, where it will interfere with
the operation of the boat or where it might
be submerged.
Do not mount any part where it will interfere
with launching or retrieving the boat.
Do not mount any part within 0.5 m (20")
of the plane of a radar antenna.
Mount the compass and gyro:
At least 1 m (3 ft) away from sources
of electrical signals or noise, such as
the batteries, high-current cables,
other boat cables, engines, fl uorescent
lights, power inverters, radio or radar
transmitters and antennas.
At least 1 m (3 ft) away from equipment
containing a magnet, such as a
compass.
3-2-2 Wiring guide
The G-PILOT 3100 has two kinds of cables:
The heavy-duty power supply and steering
drive usually require high-current cables:
Select the wire gauge from the wire size
table (see section 3-4-2).
Fit high-current cables at least 1 m (3
ft) away from other electronic devices in
the boat.
Keep the cables as short as possible.
Twin 2 mm (#14) cable is supplied with the
G-PILOT 3100 and can be used for the high
current cable if its gauge is suitable.
All the other cables are low-current:
Fit low-current cables at least 1 m (3 ft)
away from sources of electrical signals
or noise, such as the high-current cables,
other boat cables, engines, fluorescent
lights, power inverters and radio or radar
transmitters and antennas.
If the cable for the rudder feedback unit,
compass or gyro is too long, do not shorten
the cable; instead coil the cable up near the
main control unit.
The cable for the rudder feedback unit,
compass or gyro can be extended by
adding a 10 m (33 ft) extension cable and
coupling connector. Do not fi t more than
one extension cable to each unit.
When fi tting any type of cable:
Do not crush, pinch or strain the cable.
Secure the cable at regular intervals.
Ensure no connectors or exposed terminals
are in the bilge.
