4.3 Connecting Load
 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.
 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 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.
 After checking phase number and voltage of the load,
make sure to connect them correctly.
