First of all, the input of the regulator is connected to the power distribution board, and the fuse in line with the power guarantee rate of the instrument is installed on the user's power distribution board to ensure the safety of electricity consumption.

Secondly, the power supply of the electrical equipment is connected to the output end of the instrument. Note that the rated input voltage of the electrical equipment should be consistent with the output of the voltage regulator.

Third, first turn on the power switch of the voltage regulator, and the working indicator light is on. Observe whether the indicating value of the voltmeter is normal. When the output voltage is normal, open the power switch of the electrical equipment, the regulator can automatically adjust the voltage and normal power supply.

Fourth, when you do not use electrical equipment for a long time, please turn off the power switch of electrical equipment to reduce power consumption and extend the service life of the regulator.

Fifth, the regulator can not overload. When the mains voltage is low, the output capacity is reduced, so the load of the regulator should also be reduced accordingly. (From: Home of electrical technology www.dgjs123.com)

Sixth, when refrigerators, air conditioners, water pumps and other equipment with motor operation choose electrical appliances, more than 3 times the capacity of the regulator should be used to prevent the starting current of the equipment from exceeding the regulator fuse current or overcurrent protection circuit breaker current to burn the regulator fuse or jump the circuit breaker or the voltage drop is too large to work.

Seventh, the wire connecting the regulator should have enough load surface to prevent heat and reduce pressure drop. The voltage regulator with a capacity of more than 2KVA should be connected with a terminal, and a single copper wire should be selected. The terminal screw should be tightened as much as possible to prevent the joint from heating.

Eighth, whether it is single-phase or three-phase voltage regulator, after connecting all the input and output lines, first turn off the power switch of the load, and then turn on the voltage regulator, check the output voltage is normal, and then turn on the power switch of the load.
