1. Ambient air temperature: -5oC~+40oC, the highest monthly mean temperature should not exceed +30oC;
2. Altitude for installing place should not exceed 1000m;
3. When the ambient air temperature is +40, the relative humidity should not exceed 50%, and it allows higher 

relative humidity under lower temperature. Max average humidity in the dampest month is 90%, meanwhile the

lowest average temperature of this month is +25oC, and condensation on the product surface caused by 

temperature change should be taken into consideration.
