Working Environment

□ Ambient air temperature: ambient temperature -5℃ to +40℃, and the 24-hour average temperature value does not exceed Over +35°C. Users whose ambient air temperature is higher than +40°C or lower than -5°C should consult with the manufacturer.

□ The highest temperature of atmospheric humidity: when the degree is +40℃, the relative humidity does not exceed 50%, and the maximum relative humidity per month Degree 90%, resistant to the influence of humid air on the sea, and can allow higher relative humidity at lower temperatures , special measures should be taken for the occasional condensation caused by temperature changes.

□ Installation altitude: The altitude of the installation site does not exceed 2000 meters. When used at higher altitudes, the dielectric strength and cooling effect of the air should be considered to be reduced, please consult with the manufacturer.

□ Pollution level: The environmental pollution level of the installation site is level 3 .

□ Installation category: IV .

□ Installation inclination: the product is fixedly installed in the cabinet, the maximum inclination is ±22.5° .

□ Arcing distance: The arcing distance is 30mm when AC 400V. The arcing distance when AC 690V is 60mm.
