4. Red positive wire
5. Black negative wire.
6. In-line 10 A fuse.
7. NMEA 0183 wires.
8. Loud hailer wires
The unit should be powered from a dedicated circuit breaker,
that has appropriate circuit protection. If the unit is not powered
directly from a dedicated circuit breaker then a separate isolation
switch should be fitted to the units power supply.
The unit is powered on when the power cable is attached to the
vessel’s power supply.
Important: When the vessel is unattended the unit should
always be switched off by the circuit breaker or isolation
switch.
Warning: Chassis grounding
Do NOT ground this product using the chassis
ground terminal.
Grounding this product to a vessel’s RF ground
may cause galvanic corrosion.
Grounding
This product is grounded through the 0 V dc negative wire on
the power cable and does not require a drain (shield) to be
connected to the base station’s ground terminal.
Warning: Positive ground systems
Do not connect this unit to a system which has
positive grounding.
Breakers, fuses and circuit protection
The power cable includes an in-line fuse. It is recommended that
you fit an additional thermal breaker or fuse at the distribution
panel.
In-line fuse rating Thermal breaker rating
10 A in-line slow-blow fuse fitted
within power cable 7 A (if only 1 device is connected)
Note: The suitable fuse rating for the thermal breaker is
dependent on the number of devices you are connecting. If in
doubt consult an authorized Raymarine dealer.
Sharing a breaker
Where more than 1 piece of equipment shares a breaker you
must provide protection for the individual circuits. E.g. by
connecting an in-line fuse for each power circuit.

Where possible, connect individual items of equipment to
individual circuit breakers. Where this is not possible, use
individual in-line fuses to provide the necessary protection.
