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 a 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.

Grounding the switch with a grounding strip

WARNING!

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:

1.

Attach the two-hole grounding lug of the grounding cable to a grounding point on the chassis.
For more information, see "
