• You MUST fit a suitably rated fuse or breakerbetween the red wire and the battery’s positiveterminal.• Refer to the inline fuse ratings provided in theproduct’s documentation.• If you need to extend the length of the powercable, ensure you use suitably rated cable andthat sufficient power (12 V dc) is available at theSeaTalkng® backbone’s power connection.A Battery connection scenario A: suitable for a vessel witha common RF ground point. In this scenario, if yourproduct’s power cable is supplied with a separate drainwire then it should be connected to the vessel’s commonground point.B Battery connection scenario B: suitable for a vesselwithout a common grounding point. In this case, if yourproduct’s power cable is supplied with a separate drainwire then it should be connected directly to the battery’snegative terminal.Implementation — connection to distributionpanel• Alternatively, the SeaTalkng® power cable may beconnected to a suitable breaker or switch on thevessel's distribution panel or factory-fitted powerdistribution point.• The distribution point should be fed fromthe vessel’s primary power source by 8AWG(8.36mm2) cable.• Ideally, all equipment should be wired to individualsuitably-rated thermal breakers or fuses, withappropriate circuit protection. Where this is notpossible and more than 1 item of equipmentshares a breaker, use individual in-line fusesfor each power circuit to provide the necessaryprotection.• In all cases, observe the recommendedbreaker / fuse ratings provided in the product’sdocumentation.• If you need to extend the length of the powercable, ensure you use suitably rated cable andthat sufficient power (12 V dc) is available at theSeaTalkng® backbone’s power connection.Important: Be aware that the suitable fuse ratingfor the thermal breaker or fuse is dependent on thenumber of devices you are connecting.More informationRaymarine recommends that best practice isobserved in all vessel electrical installations, asdetailed in the following standards:• BMEA Code of Practice for Electrical andElectronic Installations in Boats• NMEA 0400 Installation Standard• ABYC E-11 AC & DC Electrical Systems on Boats• ABYC A-31 Battery chargers and Inverters• ABYC TE-4 Lightning ProtectionSharing a breakerWhere more than 1 piece of equipment shares abreaker you must provide protection for the individualcircuits. E.g. by connecting an in-line fuse for eachpower circuit.1 Positive (+) bar2 Negative (-) bar3 Circuit breaker4 FuseWhere possible, connect individual items ofequipment to individual circuit breakers. Where thisis not possible, use individual in-line fuses to providethe necessary protection.Warning: Product groundingBefore applying power to this product,ensure it has been correctly grounded, inaccordance with the instructions provided.28
