If there is no ground bar but earth nearby and the grounding body is allowed to be
buried, you can simply hammer an angle iron or steel pipe no shorter than 0.5 m
into the earth.
Caution:
The yellow-green PGND wire should be welded with the angle iron (steel pipe) and the
joint should be processed against eroding. (For the S9500 series, the grounding screw
is on the rear panel. Connect it as illustrated in Figure 3-5).
