5-14 Raynav 300 GPS Plotter
➤ Connect the power supply using the standard power cable supplied:
1. Connect the moulded power plug to the PWR/NMEA connector on
the rear of the Plotter. Run the free end back to the vessel’s distribu-
tion panel or, if insufficient cable length, to a junction box.
2. Cut the cable to length and connect the red wire, via a fuse, to the +ve
battery terminal and the black wire to 0V (-ve battery terminal). Pro-
tect the circuit with a 1A quick blow fuse or circuit breaker.
3. Use a suitable junction box to connect to NMEA equipment if
required.
4. Cut any unused cores short or insulate and tape back.
Note: If the power connections are accidentally reversed, the system will
not function. Use a voltmeter to check that the input power leads are the
correct polarity.
SeaTalk Connector
The Plotter can be connected to an existing SeaTalk system by
connecting a SeaTalk cable (available from your Raymarine dealer) into
the SeaTalk connector on the rear of the Plotter. The data is passed from
instrument to instrument via the daisy chained cable.
Note: The SeaTalk connector cannot be used to power the Plotter. Power
is not supplied to other SeaTalk equipment.
5.7 System Check and Initial Switch On
When you have installed your Plotter and made all the connections, you
need to check your installation before using the system for navigation. If
you encounter any problems, refer to Chapter 6: Maintenance & Fault
Finding.
EMC Conformance
Always check the installation before going to sea to make sure that it is
not affected by radio transmissions, engine starting etc.
System Check
Before performing the functional test, check that:
• All connections have been made.
• All connecting wires are secured and protected.
