Installation Procedures
Always wear safety goggles, ear protection, and a dust mask
when drilling, cutting, or sanding.
When drilling or cutting, always check what is on the opposite
side of the surface.
After you have planned the autopilot installation on your boat
and satisfied all of the mounting and wiring considerations for
your particular installation, you can begin mounting and
connecting the components.
Helm Control Installation
A dedicated helm control is not included in all autopilot
packages. If you install the autopilot without a dedicated helm
control, the autopilot CCU must be connected to the same
NMEA 2000 network as a compatible Garmin chartplotter to
configure and control the autopilot system.
Detailed mounting instructions are included in the helm control
box.
Mounting the CCU
1
Determine the mounting location.
2
Using the CCU as a template, mark the two pilot hole
locations on the mounting surface.
1
3
Using a 3 mm (
/
in.) bit, drill the pilot holes.
8
4
Use the included screws to attach the CCU to the mounting
surface.
NOTE: If you use mounting hardware other than the provided
screws, the hardware must be quality stainless or brass
material to avoid magnetic interference with the CCU.
Test any mounting hardware with a handheld compass to
make sure no magnetic fields are present in the hardware.
ECU Installation
Mounting the ECU
Before you can mount the ECU, you must select a location and
determine the correct mounting hardware
Connection Considerations, page
1
Hold the ECU in the intended mounting location and mark the
locations of the mounting holes on the mounting surface,
using the ECU as a template.
2
Using a drill bit appropriate for the mounting surface and
selected mounting hardware, drill the four holes through the
mounting surface.
3
Secure the ECU to the mounting surface using the selected
mounting hardware.
Connecting the ECU to Power
When connecting the power cable, do not remove the in-line
fuse holder. To prevent the possibility of injury or product
damage caused by fire or overheating, the appropriate fuse
must be in place as indicated in the product specifications. In
addition, connecting the power cable without the appropriate
fuse in place voids the product warranty.
CAUTION
NOTICE
(ECU Mounting and
2).
WARNING
You should connect the ECU power cable directly to the boat
battery, if possible. Although it is not recommended, if you
connect the power cable to a terminal block or other source, you
must connect it through a 40 A fuse.
If you plan to route the ECU power through a breaker or a switch
near the helm, you should consider using an appropriately sized
relay and control wire instead of extending the ECU power
cable.
1
Route the connector-terminated end of the ECU power cable
to the ECU, but do not connect it to the ECU.
2
Route the bare-wire end of the ECU power cable to the boat
battery.
If the wire is not long enough, it can be extended
Cable Extensions, page
3
Connect the black wire (-) to the negative (-) terminal of the
battery, and connect the red wire (+) to the positive (+)
terminal of the battery.
4
After you install all of the other autopilot components,
connect the power cable to the ECU.
Power Cable Extensions
If necessary, you can extend the power cable using the
appropriate wire gauge for the length of the extension.
