5-2-8 CONNECTING TO DOMESTIC CIRCUITS (HOUSE WIRING) WARNING : All Robin generators are a neutral ungrounded type. If a generator is to be connected to residential or commercial power lines, such as a stand-by power source during power outage, all connections must be made by a licensed electrician. Failure in connection may result in death, personal injury, damage to generator, damage to appli- ances, damage to the building's wiring or fire.

5-3 GENERATOR OPERATION Fig. 5-11 5-3-1 GENERATION of NO-LOAD VOLTAGE (1) When the generator starts running, the permanent magnet built-in to the rotor generates 3 to 6V of AC voltage in the main coil and condenser coil wound on the stator. (2) As one or two condensers are connected to the condenser coil, the small voltage at the condenser coil generates a minute current a which flows through the condenser coil. At this time, a small flux is produced with which the magnetic force at the rotor’s
