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.
