■working conditions

Environmental temperature: -50 ℃~+40 ℃, and the average temperature within 24 hours does not exceed+36 ℃;

Altitude: not exceeding 2000m;

Relative humidity: not exceeding 50% when the surrounding air humidity is+40 ° C;

At lower humidity levels, there can be higher relative humidity (such as 90% at+20 ℃), allowing for moderate frost formation due to temperature changes;

The inclination angle between the equipment and the vertical plane should not exceed 5 ° during installation, and the equipment should be installed in a place without severe vibration, impact, and corrosion.
