Grounding the switch

WARNING!
Connecting the switch grounding cable correctly is crucial to lightning and EMI protection.
•
Connect the grounding cable to the grounding system in the equipment room. Do not connect it to a fire
•
main or lightning rod.
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 by using one of the following methods, depending on the grounding
conditions available at the installation site:
Grounding the switch with a grounding strip (recommended
•
Grounding the switch with a grounding conductor buried in the earth
•
Grounding the switch through the PE wire of an AC power cord
•
Grounding the switch with a grounding strip (recommended
Attach one end of the yellow-green grounding cable of the switch to the grounding post on the chassis
