Grounding the switch

	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
