instructions in this guide.
Grounding
The following requirements apply when grounding Raymarine
equipment which does not have a dedicated drain wire or shield:
Common ground point
The negative wire must be connected to a bonded common ground
point, i. e. with the ground point connected to battery negative, and
situated as close as possible to the battery negative terminal.

Implementation
If several items require grounding, they may be first be connected
to a single local point (e.g. within a switch panel), with this point
connected via a single, appropriately-rated conductor, to the boat’s
common ground.
The preferred minimum requirement for the path to ground (bonded
or non-bonded) is via a flat tinned copper braid, with a 30 A rating
(1/4 inch) or greater. If this is not possible, an equivalent stranded
wire conductor may be used, rated as follows:
• for runs of <1 m (3 ft), use 6 mm
2
(#10 AWG) (6 mm) or greater.
• for runs of >1 m (3 ft), use 8 mm
2
(#8 AWG) or greater.
In any grounding system, always keep the length of connecting
braid or wires as short as possible.
Important:
Do NOT connect this product to a positively-grounded
power system.
