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.
