Connect to Ground

Connecting the device to ground is to quickly release the lightning over-voltage and
over-current of the device, which is also a necessary measure to protect the body from
electric shock.
In different environments, the device may be grounded differently. The following
will instruct you to connect the device to the ground in two ways, connecting to the
grounding bar or connecting to the ground via the power cord. Please connect the
device to ground in the optimum way according to your specific operation environment.
Connecting to the Ground via the Power Supply
■
If the device is installed in the normal environment, the device can be grounded via the
PE (Protecting Earth) cable of the AC power supply as shown in the following figure.
Figure 3-1 Connecting to the Ground
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 Earth)
■
cable of AC power cord, please make sure the PE (Protecting Earth) cable in the
electrical outlet is well grounded in advance.
