● Ambient air temperature: -25℃~+60℃, reduce the working current and voltage can be used in the air temperature of -40℃~70℃;
● Altitude:There is no capacity reduction below 3000m, and it can be used to a higher altitude after reducing the working curent and voltage;
● Atmospheric conditions: at +40℃,the relative humidity of the air does not exceed 50%; At lower temperatures, there can be higher relative humidity,the monthly average minimum temperature of the wettest month does not exceed +25℃, the monthly average maximum relative humidity of the month does not exceed 90%, and the condensation on the product due to temperature changes is considered;
● Pollution level: Level 3 ;
● Installation category:Class Ⅲ;
● Installation conditions: The mounting surface and vertical inclination is not greater than +5°,when the coil end control voltage is not less than 85%Us,not greater than +30°for other installation methods, electrical and mechanical life will not be guaranteed;
● Shock vibration: The product shall be installed and used where there is no significant shaking, shock or vibration.
