1. Plug the input end of the voltage regulator into the power distribution board, and install a fuse in line with the power of the device on the user's power distribution board to ensure the safety of electricity consumption.

2, connect the power supply of the electrical equipment to the output end of the equipment, pay attention to the application voltage of the electrical appliance is 220V or 110V, do not connect wrong.

3, first turn on the power switch of the regulator, the operation indicator light, delay indicator light, no power output, 3-7 seconds after the power supply, investigate whether the indicator light is normal indication 220V. When the output voltage is normal (220V), turn on the power switch of the electrical equipment. The voltage regulator can automatically adjust the voltage, normal power supply.

4, when the electrical equipment is not used for a long time, please turn off the power switch of the electrical equipment and turn off the power switch of the regulator to reduce power consumption and extend the service life of the regulator.

5, the regulator shall not be used in overload. When the mains voltage is low, the output capacity is reduced, and the load of the regulator should be reduced accordingly.

6, when the electrical appliances have refrigerators, air conditioners, water pumps and other motor operation equipment, should choose more than 3 times the capacity of the regulator, to prevent the equipment to start the current over the regulator fuse current or overcurrent protection circuit breaker current to make the regulator fuse or tripping and can not work.
