Note:
The figure is to illustrate the application and principle. The power cord 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 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.

When equipotential bonding, please note that the cable should be copper wrapped Kelly
2
with its area being 6mm at least. The shorter cable the better, and use a grounding
bar to establish an equipotential bonding point.
Note: The equipotential bonding cable is not provided with our product. If needed,
please self purchase it.
