If both ground bar and the environment for burying the grounding body are not available, use the protecting earth (PE)
wire.
Make sure that the switch adopts 3-core cable with the PE wire, and the PE wire of the AC power supply has been well
grounded in the power distribution room or at the side of the AC power supply transformer.
