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 ground contact in the power outlet is not connected to the ground, report the problem and reconstruct 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.
