Installation Procedures
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.
CCU Installation
To install the CCU, you must mount it to your boat ( page 10 ),
connect it to the pump ( page 11 ), connect it to a NMEA 2000
network ( page 2 ), and connect it to the alarm ( page 11 ).
Installing the CCU Mounting Bracket
Before you can mount the CCU, you must select a mounting
location ( page 1 ) and determine the correct mounting hardware
( page 1 ).
The CCU bracket has two portions, the mounting portion and
the securing portion.
1
Use the mounting portion of the CCU bracket as a mounting
template.
If you are installing the CCU on a vertical surface, install the
bracket with an opening at the bottom, so that the cables can
hang straight down and are not blocked by the mounting
hardware
À
.
2
Use a pencil to mark the pilot-hole locations at the mounting
location.
3
Drill the pilot holes.
4
Use screws
Á
to secure the CCU bracket to the mounting
location.

1 Connect the CCU cable and the NMEA 2000 drop cable to
the CCU.
2 Place the CCU in the CCU bracket with the wires

hanging
