Connecting to the Ground via the Power Supply
■
If the device is installed in the normal environment, the device can be grounde d via the
PE (Protecting Earth1 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 Ear th1 cable

of AC power cord, please make sure the PE (Protecting Earth1 cable in the electrical
outlet is well grounded in advance.
EquiCotential Bonding111 Equipotential Bonding is the practice of intentionally electrically connecting all earthed
systems to th e same groundi ng grid or c onnecting the grounding grids of al l the
earthed s ystems tog ether throug h the g round or overground m etal so as to create
an earthed equipotential zone. When lightning occurs, th e high voltag e produced by
lightning current in all sys tems will meanwh ile exist in their ground cables, and thus
all ground cables have the same electrical potential and basically eliminate the elec tric
strikes between the systems.
The figure below illustrates how to practice equipotential bon ding in a network.
