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 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 a grounding strip at the installation site or the AC power cord
connected to the switch.
NOTE:
The power and grounding terminals in this section are for illustration only.
