Grounding and RFI

The AP35 system has very good RFI protection and all units are using the
Junction Unit as common ground/shield connection. The Junction Unit
should therefore have a proper ground connection to the hull.
ROBNET 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 and winches.
Note!
The Mains input
is not polarity
protected on
J300X-40.
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.
Leave sufficient free wires 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.
