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 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.
Figure 4-1
Note:
The grounding bar and the ground cable are not provided with our product. If needed, please
self purchase them.
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.
