Environmental Requirement

Temperature and Humidity

The ambient temperature is among-10 °C~ +40 °C and the frequency inverter has to derate by 4% for every additional 1 °C if the ambient temperature exceeds 40 °C. The temperature cap is 50 °C. Relative humidity of the air≤ 90%. No condensation is allowed.


The low voltage inverter can run at the rated power if the installation site is less than 1000m(including 1000m) above the sea level. But it has to derate if the altitude exceeds 1000m. See the following figure for details:(Relationship between output current and altitude)

Other Environment Requirements

The low voltage drives can not bear fierce impact or shock. So the oscillation range should be less than 5.8m/s2(0.6g).

The low voltage converter should keep away from the electromagnetic radiation source.

The low voltage boost converter should keep away from water and condensation.

The low voltage driver should keep away from contaminative air, such as corrosive gas, oil mist and conductive dust.

The low voltage inverters should keep away from direct sunlight, oil mist, steam and vibration environment.
