2. General
This section describes how to install the autopilot and system components
described in chapter1.
Planning the Installation
When selecting power cable it is important to use the stated wire gauge.
The cable you choose may meet the required current specification,
however, if too small, the voltage will drop between the supply and the
course computer. This will reduce the power of the drive unit and may
cause the electronics to malfunction.
2.1 Course Computer
The course computer must be located in a dry, protected location free
from high operating temperatures and excessive vibration. The unit must
be mounted vertically with free air flow to allow heat dissipation from the
power amplifier.
Avoid mounting the course computer:
• in an engine room
• where there is water splash/spray from bilge’s or hatches
• where it can be subjected to physical damage from heavy items (such
as hatch covers, tool boxes etc.)
• where it will be covered by other on-board equipment
• where it will be close to sources of high RF energy transmissions
(generators/SSB radios/ antenna cables etc.)
