Check that the equipment to be connected is switch off. When the
equipment to be used is switched on, it will operate suddenly, and injuries
or accidents may be caused.
4. Switch on the equipment output indicator light will glitter (light). In case of overload
operation or when trouble occurs for the equipment being used, the output indicator light
(green) will go out, the overload indicator light (red) will light continuously, and no power
will be put out. At this time, the engine will not stop, so that the engine must be stopped
by setting the respective engine switch to STOP.
Fig 13 13.1 When overload or short circuited, overload indicator will illuminate (red)
13.2 Normal: output indicator will illuminate
When equipment requires a large starting power, the overload indicator
lights (red) and the output indicator light (green) may light together for a
short time, 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 using the DC output, turn Smart Throttle to the OFF position. The DC current will be
below 5A if turning on the Smart Throttle without AC current output.
§ When charging batteries, person must be present to monitor the voltage. Stop charging
when the voltage of the batteries is above 16V. Or it may cause battery explosion,
resulting in serious injury or death.
