[Note]
The installation o f a leakage relay on the machine can not become a reason for
elimination of the need for the load side grounding.
The load side grounding is indispensable for earliest possible detection of any
leakage caused in the generator. The absence o f such grounding requires any
leakage to be detected by current flowing through the human body and is very
dangerous because the sensitivity o f leakage relay provided on the machine is
not sufficient for detection o f such current.
^Precaution in grounding
Ф 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.
Ф
I f burying the grounding rod on the place that many pedestrians walk on, clamp the
lead wire to prevent catching on it.
(3) I f the lead wire is not long enough for the connection, connect it as directed below:
(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.
© Avoid the places within 2m of lightning conductor grounding location for burying of
grounding rod.
© Do not use a telephone set grounding conductor.
