Grounding the switch by using the AC power cord

If the installation site does not have any 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 wire.

• 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.
