18 RC435 and RC435i Chartplotters
➤ Connect to the power supply using the power cable supplied:
1. Connect the molded connector to the POWER/NMEA connector on
the rear chartplotter. Run the free end back to the vessel’s distribution
panel or to a junction box.
2. Cut the cable to length and connect the red wire (via a 1A quick blow
fuse) to the + battery terminal and the black wire to the – terminal.
3. Use a suitable junction box to connect to any NMEA equipment.
4. Cut any unused wires short or insulate and tape back.
If the power connections are accidentally reversed, the system will
not function. Use a voltmeter to check that the input power leads are
connected with the correct polarity.
