Connect to Ground
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.
•
Connecting to the Grounding Bar
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.
Tips:
The Grounding Bar is not provided with our product.
•
Connecting to the Ground via the power supply
If the switch is installed in the normal environment, the switch can be grounded
via the PE
（

cable of the AC power supply. Please make sure
the PE (Protecting Earth) cable in the electrical outlet is well grounded in
advance.
