Grounding the switch by using the AC power cord
If the installation site has no grounding strips or earth ground, you ground an AC-powered switch through
the PE wire of the power cord, but must make sure:
• The power cord has a PE terminal.
• The ground contact in the power outlet is securely connected to the ground in the power distribution
room or on the AC transformer side.
• The power cord is securely connected to the power outlet.
NOTE:
If the
round contact in the power outlet is not connected to the
round, report the problem and reconstruc
the grounding system.

NOTE:
To guarantee the grounding effect, use the grounding cable provided with the switch to connect to the
grounding strip in the equipment room as long as possible.
