2.
Place the switch with bottom up, and clean the round holes in the chassis bottom with dry cloth.
3.
Attach the rubber feet to the four round holes in the chassis bottom.
4.
Place the switch with upside up on the workbench.
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 with a grounding strip
•
Grounding the switch by using the AC power cord
•
Grounding the switch with a grounding conductor buried in the earth ground
Grounding cable
The 3600 v2 Switch Series 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
Figure 21
