3.2 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 ground
via the power supply or connecting to the ground via the grounding terminal. Please
connect the device to ground in the optimum way according to your specific operation
environment.
Note:
For the device without grounding terminal, please refer to the first way
Connecting to the Ground via the Power Supply only.
■
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.
