3.7Autopilot computer installation

The autopilot computer is designed to operate in a location that provides

ambient temperatures below +55°C (+130°F).

Note ! The autopilot computer units (AC10, AC20 and

AC40) are not weatherproof and should be mounted vertically as shown in a dry place between the control unit and the drive unit.

3.8Cable connections

Use only shielded cables. This includes Mains input, drive units and if necessary for the extension of the RF300 Rudder Feedback cable. The clutch/bypass cable and the solenoid cable should be 1,5 mm2 (AWG14). Signal cables should be 0.5 mm2 (AWG20) twisted pairs.

The mains supply cable and the drive unit motor cable should have sufficient wire gauge. This will minimize voltage drop and allow the drive unit to operate at full power.
