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.
Grounding — additional dedicated drain wire required (CP470 only)
The CP470 requires an additional dedicated drain wire. This wire supplements the drain wire (shield)
that is part of the product’s power cable.
