Specifications

In-line fuse and thermal break
er
ratings
The following in-line fuse and thermal breaker ratings
apply to your product:
In-line fuse rating Thermal breaker rating
10 A
7 A (if only connecting
one device)
Note:
• The suitable fuse rating for the thermal break
er
is dependent on the number of devices you are
connecting. If in doubt consult an authorized
Raymarine
®
dealer.
• Your product’s power cable may have a fitted
in-line fuse. If not, add an in-line fuse to the positive
wire of your product’s power connection.
Grounding
This product is grounded through the0Vdcnegative
wire on the power cable and does not require a drain
(shield) to be connected to the base station’s ground
terminal.
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.
Power distribution
Recommendations and best practice.
• The product is supplied with a power cable, either
as a separate item or a captive cable permanently
attached to the product. Only use the power cable
supplied with the product. Do NOT use a power cable
designed for, or supplied with, a different product.
• Refer to the
Power connection section for more
information on how to identify the wires in your
product’
s power cable, and where to connect them.
• See below for more information on implementation for
some common power distribution scenarios:
Important:
• When planning and wiring, tak
e into consideration
other products in your system, some of which (e.g.
sonar modules) may place large power demand
peaks on the vessel’s electrical system, which may
impact the voltage available to other products
during the peaks.
• The information provided below is for guidance
only, to help protect your product. It covers
common vessel power arrangements, but does
NOT cover every scenario. If you are unsure how
to provide the correct level of protection, please
consult an authorized dealer or a suitably qualified
professional marine electrician.
Implementation — connection to distribution panel
(Recommended)
1
Waterproof fuse holder containing a
suitably-rated inline fuse must be fitted.
For suitable fuse rating, refer to:
In-line
fuse and thermal breaker ratings
.
2
Product power cable.
3
Drain wire connection point.
• It is recommended that the supplied power cable
is connected to a suitable breaker or switch on the
vessel's distribution panel or factory-fitted power
distribution point.
• The distribution point should be fed from the vessel’s
primary power source by 8 AWG (8.36 mm
2
) cable.
• Ideally, all equipment should be wired to individual
suitably-rated thermal breakers or fuses, with
appropriate circuit protection. Where this is not
possible and more than 1 item of equipment shares a
breaker, use individual in-line fuses for each power
circuit to provide the necessary protection.

Waterproof fuse holder containing a
suitably-rated inline fuse must be fitted.
For suitable fuse rating, refer to:
In-line
fuse and thermal breaker ratings
.
Important:
Observe the recommended fuse / breaker ratings
provided in the product’s documentation, however
be aware that the suitable fuse / breaker rating
is dependent on the number of devices being
connected.
Implementation — direct connection to battery
• Where connection to a power distribution panel is not
possible , the power cable supplied with your product
may be connected directly to the vessel's battery, via
a suitably rated fuse or breaker.
