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 below illustrates how to practice equipotential bonding in a network.

When equipotential bonding, please note that the cable should be copper wrapped Kelly

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.
