4.5 Grounding
Grounding protects the switch from lightning and interference. Therefore, you must ground
the switch properly. You need to ground the switch before it is powered on and disconnect
the grounding cable after the switch is powered off.
The switch provides a grounding screw on the top panel for chassis grounding. After
crimping one end of the grounding cable to a cold pressed terminal, secure the end to the
grounding screw and connect the other end to the earth firmly.
