2.3.5 Connecting to Power Cables

CAUTION
Before connecting the power cable, confirm whether the input voltage is between 6V DC
and 36V DC. If it is out of the range, it will damage the device.
Please make sure that the positive and negative poles of the power are connected
correctly. If not, the device may be damaged.
The diameter of the power cable should be more than 1.0 mm
recommended by our company.
When connecting the cables to the device, make sure that the main power switch of the
vehicle is turned off and the key of the vehicle is placed in the off state.
2.3.5.1 Introduction of Power Cable
For the power cable of the device, see Figure 2-29.
Connect one end of the power cable to the power port of the device (the left port in the figure) or
directly use the power cable from the device. Connect the other end to the vehicle battery (the
right port in the figure). The red one with fuse is positive pole of the power (normal live). The
black one is the grounding cable. The orange one is the ACC signal (Keylive).
2.3.5.2 Obtain Connection Modes of the Main Power Switch
In order to ensure correct cable connection, it is necessary to obtain the connection mode of
the main power switch through three methods (is the main power switch connected to the
positive or negative pole of the battery?).
Ask the vehicle to manufacture the connection modes of the main power switch of
the vehicle.
Measure with a multimeter: disconnect the main switch, then measure the voltage between
the vehicle body and the positive pole of the vehicle battery. If the voltage is 12V or 24V, it
means that the main switch disconnects the positive pole. If the voltage is 0V, then the
main switch disconnects the negative pole.
Visual inspection: whether the switch cable near the vehicle battery is connected to the
positive pole or the negative pole.
2.3.5.3 Connecting Operation
The driving recorder must be connected to the ground wire. ACC signal, and constant
electricity.
Step 1 Enable the main power switch on the vehicle, place the key in the OFF state, and then
measure the normal live electricity of the vehicle.
