32 Installing the Radio TM9300/TM9400 Installation Guide© Tait Limited December 2015To reduce the standby current from 50mA to <3 mA without using theignition signal, connect pin 4 (AUX GPI3) and pin 15 (GND) of theauxiliary connector.Connecting thePower Cable Notice Although it is possible to connect the radio in line with thevehicle ignition, this is not recommended, as it may draw too much cur-rent and damage the vehicle wiring and steering column or ignitionswitch. This may also cause the supply voltage of the radio to dropbelow the specified level.Notice Disconnecting the vehicle’s battery may cause problems withsome electronic equipment, such as vehicle alarms, engine managementsystems, and in-vehicle entertainment systems. Check that the vehicleowner has the necessary information to make all electronic equipmentfunction correctly after battery reconnection.Notice If the battery is not disconnected, exercise extreme cautionduring the installation and install the fuses only when the installation isready to be checked. For more information, refer to “Checking theInstallation” on page 40.1. Disconnect the vehicle’s battery unless specifically prohibited fromdoing so by the customer, vehicle manufacturer, agent, or supplier.Notice Route the cable in a manner that minimizes coupling of elec-tric vehicle systems such as alternators into the radio.Notice Protect the power cable from engine heat, sharp edges andfrom being pinched or crushed.2. Run the power cable between the radio’s mounting position and thepower source and cut it to length, allowing approximately 8 inches(200 mm) excess at the radio end.3. Plug the power cable into the power connector of the radio.Warning Danger of fire! The radio’s protection mechanismsrely on the correct fuses on both the negative and positive powersupply leads being present. Failure to fit the correct fuses mayresult in fire or damage to the radio.The correct fuse types are:■ 30-50W radios: 20A fuses (Tait IPN 265-00010-81)■ 25W radios: 10A fuses (Tait IPN 265-00010-80)4. Cut the negative and the positive wires where the in-line fuse holderswill be placed (as close to the power source as possible).Notice Do not install the fuses until the installation is ready to bechecked.
