Grounding the switch by using the AC power cord
If the installation site has no grounding strips, ground an AC-powered switch through the protective earth
(PE) wire of the power cord. Make sure that:
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. If the ground contact in the power outlet
is not connected to the ground, report the problem and reconstruct the grounding system.
