When equipment requiring a large starting power, like a motor etc.,
is used, the overload indicator light (red) and the output indicator
light (green) may light together for a short time (about 4 sec), but
this is no abnormality. After start of the equipment, the overload
indicator light (red) will go out and the output indicator light (green)
will stay lit.
When the operation of one generator is to be stopped after start of
the equipment, the special cable for parallel operation also must be
removed at the same time.
7. When electric power is to be taken again from the generator, switch
off the equipment to be used and remove the plug from the AC
receptacle. Confirm that the equipment and the connection are
normal and that not too much power is to be taken, and then start
the engine.
