3.8 Cable 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 mm

(AWG14). Signal cables should be 0.5 mm

(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.

Refer to the table below for recommended cable sizes.

3.9 Grounding and RFI

The autopilot system has excellent RFI protection and all units

use the autopilot computer as a common ground/shield

connection. The autopilot computer should therefore have a

proper ground connection to the hull/bonding system.

Robnet2 cables and other signal cables (compass, feedback,

NMEA) should not be run in parallel with other cables carrying

RF or high current, such as VHF and SSB transmitters, battery

chargers/ generators, winches and thrusters.

Remove the bottom cover to get access to the plug-in terminals.

Strip about 1 cm (0.4") of the cable's insulation and pull the

screen backwards to cover the insulation. Position the straps as

shown and tighten well to make sure the screen has good

contact.

Provide sufficient wire length so that the plug-in terminals can

be easily connected/disconnected.

Pull out each terminal before connecting the wires. Remove all

strands before putting on the terminal cover.
