5-14 Raychart 320 Chartplotter
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 Chartplotter. Run the free end back to the vessels dis-
tribution 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 Chartplotter 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 Chartplotter. The data is passed
from instrument to instrument via the daisy chained cable.
Note: The SeaTalk connector cannot be used to power the Chartplotter.
Power is not supplied to other SeaTalk equipment.
5.7 System Check and Initial Switch On
When you have installed your Chartplotter 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.

All connections have been made.
All connecting wires are secured and protected.
