Several precautions for installing variable frequency power supply

Several precautions for installing variable frequency power supply 1. Good smoothness and high efficiency during speed regulation. At low speed, the characteristic static closing rate is high and the relative stability is good.

2. The ambient temperature of the frequency converter is generally -10 ℃ ~ 40 ℃, and the humidity is lower than 90. If the ambient temperature is higher than 40 ℃, the converter should be derated by 5 for every 1 ℃ increase. If the ambient temperature rises by 10 ℃, the service life of the frequency converter will be halved, so the problems of the ambient temperature and the heat dissipation of the frequency converter must be solved.

3. All power products such as variable frequency and variable voltage power supply, variable voltage and regulated power supply should be away from fire source and high temperature to prevent excessive temperature.

4. Prevent the erosion of oil mist and salt on variable frequency power supply.

5. Please place the variable-frequency power supply in a well ventilated place at least 30 cm away from other objects to keep the air inlet ventilated.

6. The normal operating environment of variable frequency power supply is 0 ℃ ~ 40 ℃ and 0 ~ 90% humidity (non condensing state)

7. Avoid placing the variable frequency power supply in a place containing corrosive gas, vibration and magnetic field interference.

8. Avoid placing the variable-frequency power supply in direct sunlight, rain or wet places.
