CAUTION! Even a brief disconnection of the battery while the

engine is running results in a load dump of the car generator

producing hazardous voltages of more than 100 V.

■ Turn off the engine while connecting or disconnecting the car

battery.

Wiring diagram The wiring has to be performed according to the illustration below. If

you use TandemAutoBox both power supplies must be connected.

■ The remote voltage should not exceed the supply voltage.

Overvoltage protection of the remote pin is 100 V.

■ The remote voltage may be used for starting AutoBox with a

remote switch: KL15, for example (output of the ignition/driving

switch).

■ If you connect the remote pin to the car battery directly, the

AutoBox will always be turned on, and the car battery will soon be

exhausted if the engine is not running. Thus, a switch is highly

recommended.
