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 at one end of the grounding cable to a grounding point on the
switch chassis. For more information, see "
Connecting the grounding cable to the chassis
2.
Remove the hex nut of a grounding post on the grounding strip.
3.
Attach the ring terminal at the other end 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.

As a best practice, connect the grounding cable to the primary grounding point or auxiliary grounding
point 1 on the switch. The grounding cable and grounding screw provided with the switch are
applicable only to these two grounding points.
To use auxiliary grounding point 2, prepare a grounding cable yourself. The connection method is the
same as connecting to the other two grounding points.
Grounding the switch by using the AC power cord
If the installation site has no grounding strips, you can ground an AC-powered switch through the
protective earth (PE) wire of the power cord, but must make sure:
•
The power cord has a PE terminal.
