Bonded ground system (preferred)
RF ground system (alternative)
1. Power cable to product.
2. Drain (screen).
3.
Bonded (preferred) or non-bonded RF ground.
4. Power supply or battery.
Implementation
If several items require grounding, they may 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 maybe used, rated as follows:
• for runs of <1 m (3 ft), use 6 mm
2
(#10 AWG) 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.
