Grounding and Radio Frequency Interface
(RFI)
The AP50 system has excellent radio frequency interference
protection and all units use the junction unit as a common
ground/shield connection. The junction unit must therefore have
a proper ground connection to the hull.
RobNet cables and other signal cables (i.e. compass, feedback,
NMEA) should not be run in parallel with other cables carrying
radio frequency or high current, such as VHF and SSB
transmitters, battery chargers/generators, and winches.
Figure 4-12 J50 Junction Unit Screen Termination
Remove the bottom cover to get access to the plug-in terminals.
Strip about 1 cm (0.4 in.) 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 makes good
contact.
Provide sufficient wire length so that the plug-in terminals can
be easily connected and disconnected.
Pull out each terminal before connecting the wires. Remove all
the strands before putting on the terminal cover.
