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
Breakers, fuses and circuit protection
It is recommended that you fit a thermal breaker or fuse at the
distribution panel.
Thermal breaker rating
5 A (if only connecting one device)
Note:
The suitable fuse rating for the thermal breaker is
dependent on the number of devices you are connecting. If in
doubt consult an authorized Raymarine dealer.
