Installation
3 Cut the negative and the positive wires where the in-
line crimp fuse holders will be placed (as close to the
battery as practicable).
4 Insert each end of the negative wire into one of the in-
line crimp fuse holders and crimp them to force the
metal contacts onto the wires. Terminate the wire at
the battery earth.
5 Repeat Step 4 for the positive wire and terminate it at
the positive terminal of the battery.
Caution:
Prevent the power wires chafing on any
metal parts.

II
radios are designed to operate from a
nominal 12V negative earth supply, and require
currents of up to 8A. (The radios will tolerate a supply
voltage range of 10.8V to 16.0V). In vehicles with a
24V electrical system (e.g. many trucks), it is
essential to provide a suitably rated 24/12V converter
to isolate the radio from the battery and protect it
against excessive voltages.
6 If the economiser is to be controlled by the ignition
line, terminate a wire in the power connector and
connect the ‘ignition’ wire to a +12V supply which is
live only when the vehicle’s ignition is switched ‘On’.
