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.
