IMPORTANT:

Ensure good ventilation and 10 cm (3.9 in) of clearance around the chassis for heat dissipation.

•

Avoid placing heavy objects on the switch.

•

Grounding the switch

WARNING!

Correctly connecting the switch grounding cable is crucial to lightning protection and EMI protection.

NOTE:

The power and 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.

You can ground the switch in one of the following ways, depending on the grounding conditions

available at the installation site:

•

Grounding the switch by using the AC power cord

•

Grounding the switch with a grounding conductor buried in the earth ground

The 3100-48 v2 Switch is provided with a yellow-green grounding cable. One end of the cable has an

OT terminal, and the other end is naked and soldered, as shown in

Grounding the switch with a grounding strip

When a grounding strip is available at the installation site, connect the grounding cable to the

grounding strip.
