Note: The grounding bar and the ground cable are not provided with our product. If 
needed, please self purchase them.

If the device is installed in the normal environment, the device can be grounded via the 
PE (Protecting Earth1 cable of the AC power supply as shown in the following figure.

the package and the socket in your situation will comply with the regulation in your 
country, so they may differ from the figure above.

of AC power cord, please make sure the PE (Protecting Earth1 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 below illustrates how to practice equipotential bonding in a network.
