7 CONNECTIONS AND INSTALLATION Ground connection The transceiver and antenna tuner MUST have an adequate ground connection Otherwise the overall efficiency of the transceiver and antenna tuner in stallation will be reduced Electrolysis electrical shocks and interference from other equipment could also occur For best results use the heaviest gauge wire or strap available and make the connection as short as possible Ground the transceiver and antenna tuner to one ground point otherwise voltage differences between 2 ground points may cause electrolysis Good ground points Ship s ground terminal External ground plate External copper screen Acceptable ground points Stainless steel tuna tower Stainless steel stanchion Through mast Through hull Metal water tank Undesirable ground points P CAUTION The IC M710 has either a negative ground or floating ground depending on version NEVER connect the negative ground type to a plus grounding ship otherwise the transceiver will not function Ground system example these points may cause noise or electrolysis Engine block Keel bolt Unusable points these connection may cause an explosion or electrical shock Gas or electrical pipe Fuel tank Oil catch pan Power source The transceiver requires regulated DC power of 13 6 V and at least 30 A There are 3 ways to supply power Direct connection to a 12 V battery in your ship through the supplied DC power cable Use the PS 60 DC POWER SUPPLY to connect to an AC outlet Use the PS 66 DC DC CONVERTER to connect to a 19 32 V DC power source CAUTION The supplied DC power MUST be used to provide power to the cable trans ceiver AVOID exceeding the 3 m 10 ft length m of the DC power cable If it is necessary to make a run of over 3 m use 6 or similar cable instead of the supplied DC power cable for a maximum run of 6 m 20 ft 18 DC power cable connection NOTE Use terminals for the cable connection cable
