Tait TM8105 User Manual - Power Cable

Radio Installation 25

Power Cable

Caution: This radio is designed to operate from 

a nominal 12V negative ground supply and may 

draw up to 8A of current. The radio will tolerate 

a supply voltage range of 10.8V to 16.0V at the radio.

In vehicles with a supply voltage greater than 16.0V, 

such as many trucks, it is essential to provide a suitably 

rated DC to DC converter. This will isolate the radio from 

excessive battery voltage and provide the correct DC 

operating conditions.

Installing the Power Cable

Caution: Disconnecting the vehicle’s battery 

may cause problems with some electronic 

equipment, such as vehicle alarms, engine 

management systems and in-car entertainment systems. 

Check that the vehicle owner has the necessary informa-

tion to make all electronic equipment function correctly 

after battery reconnection.

1. Disconnect the vehicle’s battery, unless specifically 

prohibited from doing so by the customer, vehicle 

manufacturer, agent or supplier.

If the battery is not disconnected, exercise extreme 

caution throughout the installation and install the 

fuses only when the installation is ready to be 

checked (see “Installation Checks” on page 28).

2. Determine where the power cable will be routed. 

Caution: The power cable should be 

protected from engine heat, sharp edges 

and from being pinched or crushed.
