Connecting Load
Make sure not to connect the output terminal of
the machine with the commercial power source from
electric power company. This is not only prohibited by
the regulations, but it may cause an electric shock,
machine troubles and even a fire.
Make sure to ground the machine and the load. It could
cause an electric shock when the machine is installed at
a damp place or on a steel frame or a steel plate.
Never touch the output terminals during operation.
Notice that the voltage of several hundreds volt is
applied to the output terminal.
When removing or connecting a connecting cable for
changing load, be sure to switch OFF the circuit breaker,
remove the starter key from the starter switch, then
carry out a work. The operator must keep the key during
operation.
For a connecting cable to load, do not use a cable with
damaged sheath nor an inappropriate insulation cable
to the voltage.
Secure connections between each cable terminal and
input/output terminal. Otherwise, it may be slackened
during operation and may cause a fire or an electric
shock accident.
Notice that the terminal O is not a grounding terminal of the generator. Never connect a grounding
wire to it. Such connection may cause the generator main unit or the load troubles.
When using a single-phase load [200/220V or 115/127V], see to it that the loads on the different
phases will be evenly balanced. Unbalanced loads may cause the generator main unit burning.
Select a cable with sufficient diameter by
considering the load capacity and the distance
from the generator to the load. Use terminals for
connection and securely fasten them. (See 3.4)
After checking phase number and voltage of the
load, make sure to connect them correctly.
