2.2.4 How to terminate of NMEA2000 connection
When the termination of NMEA2000 connection is needed in the NAVpilot, attach the re-
sistor assembly (supplied as installation materials) to the NMEA2000 cable in the proces-
sor unit.
Twist the lead wire of the resistor assembly to the NMEA2000 cable, and solder them as
below.
2.2.5 Power and motor cables
For the power cable and motor line cable, see the table below to select cables. Connect
the power cable to a breaker that has a rating acceptable to the motor.
• The thickness of the cables varies with the rated current of the motor. The table shows
the specifications for 10 or 25 A motor.
• Use single core wire or stranded wire. (For stranded wire the max. no of wires is
seven).
• Do not twist cores to prevent them from disconnecting.
