Power Supply
Connection
The AutoGRAPH-GSM controller is
connected to the power supply source
through the interface cable supplied with the
device. The device is supplied with a fuse
intended to provide a short circuit protection
of power supply. The fuse holder is installed
on a wire ring, which should be cut before
operation.
When making connections, pay special
attention to the safety rules stipulated by
the regulations for motor vehicle repair
procedures. All connections should be
properly isolated and securely connected. If
the wire is too short, it can be spliced with
a wire of at least 0.5 mm
2
cross section (20
AWG or thicker).
The power supply input of the controller
is rated for the vehicle system operating
voltage of 10-50 V DC.
Power can be fed to the controller either
before or after the vehicle’s battery
disconnect switch:

The fuse should be placed as close as possible to the point where the AutoGRAPH-GSM is
connected to the vehicle power system.
ВНИМАНИЕ
If power is connected before the vehicle battery disconnect switch, the controller shall always
be ON, therefore, it is highly recommended to use adaptive position recording for this case so
as to minimize an amount of data to be transferred, as well as to reduce GPRS and web traffic.
