Normal Operating Conditions and Mounting Conditions

Ambient temperature: -35°~70°C
Altitude: ≤3000M
Atmospheric conditions: The atmospheric relative humidity is not more than 50% when the ambient air temperature is +40°C; high relative humidity is permitted under low temperature, For example, it may be up to 90% at +20°C; special measures should be taken in case of occasional condensation due to temperature variation;
Pollution degree: level 2;
Mounting category: category II or III.
Mounting form: It is installed using the TH35-7.5 section steel mounting rail.The inclination of installing surface cannot exceed 5°.
