2. Connect to the ground

In different environments, the device may be grounded differently. The following will instruct you to connect the device to the ground in two ways. Note that the protective earthing terminal must be connected to the installation protective earthing conductor.

- Use the grounding bar

If the device is installed in the Equipment Room, where a grounding bar is available, it is recommended to connect the device to the grounding bar with an 18-14 AWG ground cable as shown in the following figure.

① Device (Rear Panel)

② Grounding Terminal

③ Ground Cable (18-14 AWG)

④ Grounding Bar

- 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.
