(3) Precaution in grounding
① Select a shady and highly moist place, and burry the grounding rod in such way
that its top end is completely hidden in the ground.
② If burying the grounding rod on the place that many pedestrians walk on, clamp
the lead wire to prevent catching on it.

1) Connect the lead wire and the extension wire by soldering or sleeve coupling
securely and apply insulating tape to the connection.
2) Do not burry the connection in the ground.
④ Avoid the places within 2m of lighting conductor grounding location for burying
of grounding rod.
