Power distribution
Raymarine recommends that all power connections
are made via a distribution panel.
• All equipment must be powered from a breaker or
switch, with appropriate circuit protection.
Warning: Product grounding
Before applying power to this product,
ensure it has been correctly grounded, in
accordance with the instructions provided.
Grounding — Dedicated drain wire
The power cable supplied with this product includes
a dedicated shield (drain) wire for connection to a
vessel's RF ground point.
It is important that an effective RF ground is
connected to the system. A single ground point
should be used for all equipment. The unit can be
grounded by connecting the shield (drain) wire of
the power cable to the vessel's RF ground point.
On vessels without an RF ground system the shield
(drain) wire should be connected directly to the
negative battery terminal.
The dc power system should be either:
• Negative grounded, with the negative battery
terminal connected to the vessel's ground.
• Floating, with neither battery terminal connected
to the vessel's ground
Warning: Positive ground systems
Do not connect this unit to a system which
has positive grounding.
Breakers, fuses and circuit protection
The information below is provided as guidance

illustrations provided are for common vessel power
arrangements, if you are unsure how to provide the

Raymarine authorized dealer for support.
Distribution panel connection
