Connection between the power cable and power supply terminal
The power supply terminal of the IDU is fixed on the main
control board, the power cable is connected to the power supply
terminal labeled "CN1" on the main control board. The live and
neutral wires are connected according to the main control board
logos "L" and "N", and the ground wire is directly connected to
the electric control box sheet metal part.

Do not bond and connect the power cable. Bonding and connecting the power cable may cause it to heat up,
resulting in a fire.
Do not press the power cables of the same wire diameter on the same side of the terminal. Do not use two
power cables of different wire diameters for the same terminal blocks; otherwise, they can easily loosen due to
uneven pressure and cause accidents, as shown in the figure below.
The connected power cable should be secured
with a wire clamp to prevent loosening, as shown
in the right figure.
The power cable must be crimped reliably using
an insulated circular terminal block, and then
connected to the power supply terminal of the IDU,
as shown in the figure below.
If it fails to crimp the insulated circular terminal block
due to on-site limitations, connect the power cables
of the same diameter to both sides of the power
supply terminal block of the IDU, as shown in the
figure below.
