Working Environment:
- Ambient air temperature: -5.C~+40.C,the highest monthly mean temperature should not exceed +30.C;
- Altitude for installing place should not exceed 2000m;
- When the ambient air temperature is +40.C 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 +25, and condensation on the product surface cause by temperature change should be taken into consideration on the product surface caused by temperature change should be taken into consideration.
