This display is not intended for use on “positive”
ground boats. The power input cable drain wires must
be connected directly to the boats ground.
Grounding
The following requirements apply when grounding Raymarine
equipment:
• Use a dedicated earthing plate (e.g. dynaplate) in contact with
the water.
• Ground cables may be routed to a common point (e.g. within the
switch panel. With a single (appropriately rated) copper braid
connecting to the earthing plate.
• Use flat tinned copper braid, 30 A rating (1/4 inch) or greater.
Equivalent stranded wire diameter 4 mm or greater.
• Keep the length of the earth braid as short as possible.
Power cable
The C-Series display is supplied with a combined power and data
multi cable, this can be extended if required.
