Raymarine AIS 350 Installation Instructions Manual page 37

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
• for runs of >1 m (3 ft), use 8 mm
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.

Connecting power
The use of crimped and soldered lugs is recommended, to provide
optimum connection to the power source.
Connect your AIS unit's power cable to either a 12 V dc or 24 V dc
power source as follows:
1. Connect the red wire to the 5 A fuse or equivalent automatic
circuit breaker to the supply's positive terminal.
2. Connect the black wire to the supply's negative terminal.
