Connecting to the Ground via the Grounding Terminal
Use the grounding bar
If the device is installed in the Equipment Room, where a grounding bar is available, you are
recommended to connect the device to the grounding bar as shown in the following figure.

self purchase them.
Equipotential Bonding
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.
