When there is no grounding strip but earth near the equipment room that allows a grounding body
to be buried, hammer an angle iron/steel pipe longer than 0.5 m into the earth, weld the
yellow-green ground wire of the switch onto the angle iron/steel pipe, and process the joint against
erosion.

For an AC-powered switch, if none of the above two conditions is available, ground it through the
PE wire of the AC power supply. In this case, make sure this PE wire is well connected to the
ground at the power distribution room or AC transformer side.
