Stop the generator immediately, check the appliance and / or generator for overloading or detect and have repaired as necessary by Robin dealer or service shop. -[CAUTION] The duplex 120V receptacle is protected by a GFCI (Ground Fault Circuit Interrupter). GFCI shuts off the output current from the duplex 120V receptacle when a ground fault occurs in the generator or the appliance. Please note that other receptacles are not protected by GFCI. GFCI RECEPTACLE After starting the engine, check the GFCI for proper functioning by the following test procedure. n Push yellow TEST button, The red RESET button will pop out exposing the word TRIP. Power is now off at the outlets protected by the GFCI, indicating that the device is functioning properly. m If TRIP dose not appear when testing, do not use the generator. Call a qualified electrician. n To restore power, push RESET button. -12- If the RESET button pops out during operation, stop the generator immediately and call a qualified electrician for checking generator and the appliances. If the RESET button pops out during operation, stop the generator immediately and call a qualified electrician for checking generator and the appliances. 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. Failure in connection may result in death, personal injury, damage to generator, dam- age to appliances, damage to the building’s wiring or fire. (a) When connecting a Robin generator to a house wiring, generator output power must be taken from the 24OV-4P receptacle. (b) Install a transfer switch. A transfer switch must be installed to transfer the load from the commercial power source to the generator. This switch is necessary to prevent accidents caused by the recovery from power outage. Use a transfer switch of the correct capacity. Install transfer switch between the meter and the fuse or AC breaker box. [CAUTION] If the neutral wire of house wiring is grounded, be sure to ground the ground terminal of the generator, Otherwise an electric shock may occur to the operator. -13- .n .n B RECEPTACLE TRA&FER SWITCH m Ii c .n 42-l 2 3-PHASE APPLICATION (RGV13OOOT only) Connection of Power Cables I n Do not touch output terminals while the generator is running or the operator may suf- fer severe electric shock resulting in death. w Be sure to shut down the generator before connecting or changing connection of power cables to the generator.

This voltage is regulated by a diode in the AVR to feed a current to the generator field coil. (FC). (See Fig. 4-1) The rotor is turned an electromagnet by that current and rotates so that voltage are gener- ated in the stator coils (main coil and sub coil). The voltage generated in the sub coils is operated by the AVR to feed a current to increase the field coil current. (See Fig. 4-2) As a result, the rotor magnetism increases. This operation is repeated to generate the rated voltage at 50 Hz or 60 Hz in the main coil and DC coil. 4-3-2 VOLTAGE REGULATING MECHANISM (RGV12000) Connect a load to the AC output terminal and increase current. Output voltage varies as shown in Fig. 4-3 depending on whether an automatic voltage regulator is used or not. The operation of the ...
