Grounding the switch
CAUTION:
•
Correctly connecting the grounding cable for the switch is crucial to lightning protection and EMI protection.
•
As a best practice to guarantee the grounding effect, connect the grounding cable provided with the switch
to the grounding strip in the equipment room.
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.
NOTE:
The power and grounding terminals positions in the figures in this section are for illustration only.
Grounding the switch with a grounding strip
CAUTION:
Connect the grounding cable to the grounding system in the equipment room. Do not connect it to a
fire main or lightning rod.
If a grounding strip is available at the installation site, connect the grounding cable to the grounding
strip.
To connect the grounding cable:
