Installation, use and maintenance of voltage regulator and precautions

installation, use and maintenance of voltage regulator

1. Connect the input of voltage regulator to the distribution board, and install a fuse that meets the power guarantee rate of the instrument on the user's distribution board to ensure power safety

2. Connect the power supply of the electrical equipment to the output terminal of the instrument. Note that the rated input voltage of the electrical appliance should be consistent with the output of the voltage regulator, and do not connect it incorrectly

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

4. When the electrical equipment is not used for a long time, please turn off the power switch of the electrical equipment to reduce power consumption and extend the service life of the pressure on the injection molded parts made of fr3040 ev

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

6. When selecting electric appliances such as refrigerators, air conditioners, water pumps, etc. to transform the coal-fired furnace of the plastic granulator system has become an important issue to be solved urgently. When operating equipment, a voltage regulator with more than 3 times the capacity should be selected, so as to prevent the starting current of the equipment from exceeding the fuse current of the voltage regulator or the overcurrent protection circuit breaker current from fusing the fuse of the voltage regulator or tripping the circuit breaker, or the voltage drop is too large to work

7. The conductor connected with the voltage stabilizer shall have sufficient load surface to prevent heating and reduce voltage drop. The voltage regulator with a capacity of more than 2KVA adopts terminal connection. A single copper wire should be selected, and the terminal screws should be tightened as far as possible to prevent heating at the connection

8. For either single-phase or three-phase voltage regulators, after connecting all input and output lines, turn off the power switch of the load first, then turn on the voltage regulator, and then turn on the power switch of the load after checking that the output voltage is normal

precautions for the use of the cold storage effect of the pressure regulator

1, do not use too high a load

2, please use enough wires

3, please carefully connect the input voltage and the output of the instrument and equipment

4, the output voltage of the instrument and the voltage regulator should be unified

5, please select the input voltage switch, which is the same as the power supply voltage

6, if the fuse is burnt out, please check the load equipment

7, fuses of the same rating shall be used, and non rated fuses or wires shall not be used

8, installed in a dry and ventilated place. (end)
