Raymarine Quantum Radome Installation Instructions Manual page 26

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 8AWG
(8.36mm 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.
• In all cases, observe the recommended
breaker / fuse ratings provided in the product's
documentation.
• If you need to extend the length of the power cable
supplied with your product, ensure you observe
the dedicated Power cable extensions advice
provided in the product's documentation.
Important: Be aware that the suitable fuse rating
for the thermal breaker or fuse is dependent on the
number of devices you are connecting.
