Grounding the wireless switch with a grounding
conductor buried in the earth ground
If earth ground is available at the installation site, hammer a 0.5 m (1.64
ft) or longer angle iron or steel tube into the earth ground to serve as a
grounding conductor. Weld the yellow-green grounding cable to the
angel iron or steel tube and treat the joint for corrosion protection.

Grounding the wireless switch by using the AC
power cord
If the wireless switch is AC powered, you ground an AC-powered wireless
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.
