Grounding the switch through the PE wire of an AC power cord

CAUTION:
Use this method only when the switch is AC powered.
If the installation site has no grounding strips or earth ground, you ground an AC-powered switch through
the protective earth (PE) wire of the power cord, and check that the ground contact in the power outlet is
well connected to the ground in the power distribution room or on the AC transformer side.
