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.
• All equipment should be wired to individual breakers
if possible.
Warning: Product grounding
Before applying power to this product,
ensure it has been correctly grounded, in
accordance with the instructions in this
guide.
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.
