Grounding the switch
WARNING! Correctly connecting the switch grounding cable is crucial to lightning protection and EMI protection. | ||
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 to minimize the potential for system damage, maximize the safety at the site, and minimize EMI susceptibility of the system.
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 conductor buried in the earth ground
Grounding the switch by using the PE wire of the AC power cord
