Connecting the device to ground is to quickly release the lightning over-voltage and
over-current of the device, which is also a necessary measure to protect the body from
electric shock.
In different environments, the device may be grounded differently. If the device is
installed in the normal environment, the device can be grounded via the PE (Protecting
Earth) cable of the AC power supply as shown in the following figure.
Connecting to the GroundFigure 3-1
Note:
The figure is to illustrate the application and principle. The power plug you get from
the package and the socket in your situation will comply with the regulation in your
country, so they may differ from the figure above.
If you intend to connect the device to the ground via the PE (Protecting Earth) cable
of AC power cord, please make sure the PE (Protecting Earth) cable in the electrical
outlet is well grounded in advance.
