Extending the power cable
The power cable may be extended up to a maximum length of 60 ft. (20m)
using a suitable AWG 12 multi stranded cable.
Note:
If the power connections are accidentally reversed the system will
not work. Raymarine recommends using a multimeter to ensure
that the power lead is connected with the correct polarity.
Grounding the system
Your boat’s power system should be either:
• Negative grounded, with the negative battery terminal connected to
the boat’s ground, or
• Floating with neither battery terminal connected to the boat’s ground.
It is important that an effective RF ground is connected to your weather
system.
You must ground your weather system by connecting the Shield wire
(screen) of the power cable to the nearest ground point on your boat’s RF
system.
If you need to extend the wire, the extension wire should be an 8 mm braid
or AWG 10 multistrand cable.
If your boat does not have an RF system, connect the Shield wire (Screen)
to the negative battery terminal.
