25EnglishInstallation3 Cut the negative and the positive wires where the in-line crimp fuse holders will be placed (as close to thebattery as practicable).4 Insert each end of the negative wire into one of the in-line crimp fuse holders and crimp them to force themetal contacts onto the wires. Terminate the wire atthe battery earth.5 Repeat Step 4 for the positive wire and terminate it atthe positive terminal of the battery.Caution: Prevent the power wires chafing on anymetal parts.Note: T2000II radios are designed to operate from anominal 12V negative earth supply, and requirecurrents of up to 8A. (The radios will tolerate a supplyvoltage range of 10.8V to 16.0V). In vehicles with a24V electrical system (e.g. many trucks), it isessential to provide a suitably rated 24/12V converterto isolate the radio from the battery and protect itagainst excessive voltages.6 If the economiser is to be controlled by the ignitionline, terminate a wire in the power connector andconnect the ‘ignition’ wire to a +12V supply which islive only when the vehicle’s ignition is switched ‘On’.
