Grounding the switch

CAUTION:
• Correctly connecting the grounding cable is crucial to lightning protection 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.
• To guarantee the grounding effect and avoid switch damage, use the grounding cable provided
with the switch to connect the switch to a grounding strip in the equipment room.
NOTE:
The 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.
To connect the grounding cable:
1. Attach the two-hole grounding lug of the grounding cable to a grounding point on the chassis.
For more information, see
2. Remove the hex nut of a grounding post on the grounding strip.
3. Attach the ring terminal of the grounding cable to the grounding post on the grounding strip, and
secure the ring terminal to the grounding post with the hex nut.
