Figure 3-8 Grounding through a grounding strip
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.

Figure 3-9 Grounding the switch by burying the grounding body into the earth
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.
