WARNING
I-----;
Electric shock and electric leak
• Make sure not to connect the output terminal of the
machine with the commercial power source from electric
power company. 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.

CAUTION----------------------,
• When using a single-phase load [277Vor 139V], see to it that the loads on the different phases will be
evenly balanced. Unbalanced loads may cause the generator burning.
• Select a cable wit h su fficient diameter by
considering the load capacity and the distance
from the generator to the load. Use terminals for
connection and securely fasten them.
• After checking phase number and voltage of the
load, make sure to connect them correctly.
