chassis ground to the earth to minimize the potential for system damage, maximize the safety at the
site, and minimize EMI susceptibility of the system.
Select a grounding method based on the installation environment.
NOTE:
The power and grounding terminals in this section are for illustration only.
Grounding the switch by using a grounding strip
CAUTION:
•
Connect the grounding cable to the grounding strip 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.
If a grounding strip is available at the installation site, use the grounding cable provided with the
switch to connect the switch to the grounding strip.
Connecting the grounding cable to the chassis
1.
Remove the grounding screw from the grounding hole in the chassis.
2.
Use the grounding screw to attach the ring terminal of the grounding cable to the grounding
screw hole. Fasten the screw. As a best practice, use a torque of 5 kgf-cm (0.49 Nm) to fasten
the grounding screw.
IMPORTANT:
Orient the grounding cable as shown in
so that you can easily install or remove the
removable components.
