• Connecting to the Grounding Bar
• Connecting to the Ground via the power supply
Connecting the switch to ground is to quickly release the lightning over-
voltage and over-current of the switch, which is also a necessary measure
to protect the body from electric shock.
In different environments, the switch may be grounded differently. The
following will instruct you to connect the switch to the ground in two ways,
connecting to the Grounding Bar or connecting to the Ground via the power
cord. Please connect the switch to ground in the optimum way according to
your specific operation environment.
If the switch is installed in the Equipment Room, where a Grounding Bar is
available, you are recommended to connect the switch to the Grounding
Bar as shown in the following figure.
If the switch is installed in the normal environment, the switch can be
grounded via the PE (Protecting Earth) cable of the AC power supply as
shown in the following figure.
