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 [277V or 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.
