Raymarine Ray 90, Installation And Operation Instruction Manual

A Battery connection scenario A: suitable for a vessel with a common RF ground point. In
this scenario, if your product’s power cable is supplied with a separate drain wire then it
should be connected to the vessel’s common ground point.
B Battery connection scenario B: suitable for a vessel without a common grounding point. In
this case, if your product’s power cable is supplied with a separate drain wire then it should
be connected directly to the battery’s negative terminal.
Implementation — connection to distribution panel
• Alternatively, the supplied power cable may be connected to a suitable breaker or switch on the
vessel's distribution panel or factory-fitted power distribution point.
• The distribution point should be fed from the vessel’s primary power source by 8 AWG (8.36 mm 2 )
cable.
• Ideally, all equipment should be wired to individual suitably-rated thermal breakers or fuses, with
appropriate circuit protection. Where this is not possible and more than 1 item of equipment shares
a breaker, use individual in-line fuses for each power circuit to provide the necessary protection.
