needed, please self purchase them.
Connecting to the Ground via the Power Supply

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 3-2
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.

Equipotential Bonding is the practice of intentionally electrically connecting all earthed
systems to the same grounding grid or connecting the grounding grids of all the
earthed systems together through the ground or overground metal so as to create
an earthed equipotential zone. When lightning occurs, the high voltage produced by
lightning current in all systems will meanwhile exist in their ground cables, and thus
all ground cables have the same electrical potential and basically eliminate the electric
strikes between the systems.
The figure bellow illustrates how to practice equipotential bonding in a network.
