The operating environment temperature is between -10℃ and +40℃. When the temperature exceeds 40℃, it should be reduced by 3% per degree Celsius. The maximum temperature should not exceed 50℃. The relative humidity of the air should be less than 90%, without condensation. The inverter can operate at its rated power when installed at an altitude of 1000m or below. When the altitude exceeds 1000m, it should be reduced by 1% per 100m in proportion. It should be installed in a place far from electromagnetic radiation sources, with a maximum acceleration of no more than 5.8m/S2 (0.6g). There should be no oil mist, corrosive and flammable gases, radioactive substances, metal dust, dust, oil, water, or other foreign substances that can enter the interior of the inverter.
