WARNING!
Correctly connecting the switch grounding cable is crucial to lightning protection and EMI protection.
The power and grounding terminals in this section are for illustration only.
The power input end of the switch has a noise filter, whose central ground is directly connected to the
chassis to form the chassis ground (commonly known as PGND). You must securely connect this chassis
ground to the earth so the faradism and leakage electricity can be safely released to the earth to
minimize EMI susceptibility of the switch.
You can ground the switch in one of the following ways, depending on the grounding conditions
available at the installation site:

Grounding the switch with a grounding strip

Grounding the switch with a grounding conductor buried in the earth ground
Grounding the switch by using the AC power cord
Grounding the switch with a grounding strip
If a grounding strip is available at the installation site, connect the grounding cable to the grounding
strip.
WARNING!
Connect the grounding cable to the grounding system in the equipment room. Do not connect it to a fire
main or lightning rod.

remove the grounding screw from the grounding point.
Attach the grounding screw to the ring terminal of the grounding cable.
