447 CONNECTION AND INSTALLATION■ Ground connectionThe transceiver and antenna tuner MUST have anadequate RF ground connection. Otherwise, theoverall efficiency of the transceiver and antennatuner installation will be reduced. Electrolysis,electrical shocks and interference from otherequipment could also occur.For best results, use 50 or 75 mm (2 or 3 inches)wide copper strap and make the connection as shortas possible. Ground the transceiver and antennatuner to one ground point, otherwise the voltagedifference (in RF level) between 2 ground points maycause electrolysis.RWARNING! When grounding to a metal hullU s e Z i n c a n o d e s t o p r o t e c t t h e h u l l f r o melectrolysis.Ask your technical dealer, installer or refer to atechnical book, etc., for RF grounding details.Ground system exampleBest ground points• External ground plate• Copper screen• Copper foilUn-usable ground points( these connections may cause an explosion or electricalshock)• Gas or electrical pipe• Fuel tank or oil-catch panCopper pipe Metal object Copper screen■ Power sourceThe transceiver requires a regulated DC power of13.8 V and at least 28 A. There are two ways tosupply power:• Direct connection to a 12 V battery in your vehiclethrough the supplied DC power cable.• Use DC power supply to connect to an AC outlet.DC power cable connectionNOTE: Use terminals for the cable connection.12 VbatterySuppliedDC power cable+ red_ black CrimpSolder
