Jcu Connection - Raymarine T303 Installation And Operation Instructoins

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.
