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.
Power cable
Depending on Multifunction display variant, the display
is either supplied with a power cable or a combined
power and data cable.
Power cables available
For flush mount installations a right angled power cable
is available.

Cable extension
Power cables can be extended if required. The following
restrictions apply to any extension to the power cable:
• Cable must be of a suitable gauge for the circuit load.
• Each unit should have its own dedicated power cable
wired back to the distribution panel.

Breakers, fuses and circuit protection
The information below is provided as guidance to help
protect your product. The example illustrations provided
are for common vessel power arrangements, if you are
unsure how to provide the correct level of protection
then please consult a Raymarine authorized dealer for
support.
Fuse and breaker rating
Fuse rating Thermal breaker rating
7 A in-line fuse fitted within
power cable. 5 A (if only connecting one
device)
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.
Note: Your product’s power cable may have an
in-line fuse already fitted, if not then you will need
to add an in-line fuse to the positive wire of your
products power connection.
