If the RESET button pops out during operation, stop the generator immediately and call a qualified electrician for checking generator and the appliances. (2) CONNECTING TO DOMESTIC CIRCUIT (HOUSE WIRING) 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.

4-3-3 CURRENT TRANSFORMER CONTROL (RGV13000T) When the engine starts, a permanent magnet implanted in the rotor rotates, creating voltage in the main coil (MC). When a load makes contact with the coil, the load current passing through the primary coil of current transformer causes a magnetizing current to flow in ratio to the load current flowing through the current transformer primary coil. This magnetizing current passing through a diode to field coil creates a strong magnetic field in th
