Seatalk Ng® Connections - Raymarine Lighthouse eS Serie Manual Del Usario

Power cable extension
The product is supplied with a power cable, which
can be extended if required.
• The power cable for each unit in your system
should be run as a separate, single length of
2-wire cable from the unit to the vessel's battery or
distribution panel.
• Raymarine recommends a minimum wire gauge
of 18AWG (0.82 mm
extension.
• For all lengths of extension to the power cable,
ensure there is a continuous minimum voltage
at the product's power connector of 10.8 V with a
fully flat battery at 11 V.
Important: Be aware that some products in
your system (such as sonar modules) can create
voltage peaks at certain times, which may impact
the voltage available to other products during the
peaks.
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: Product grounding
Before applying power to this product,
ensure it has been correctly grounded, in
accordance with the instructions provided.
Warning: Positive ground systems
Do not connect this unit to a system which
has positive grounding.
