Normal running and installation conditions
- Ambient air temperature: -5!+40, the average value should not exceed +35 within 24 hours.
- Elevation: at most 2000m.
- Atmospheric conditions: When the temperature at 40, the relative humidity of atomsphere should be at the most 50%. When at relatively low temperatures, it could have higher relative humidity. Monthly maximum relative humidity could be not more than 90%. Special measures should be taken due to occurrence of dews.
- Class of pollution: Class 3
- Installation conditions: Degree of inclination between fitting surface and vertical surface should not exceed
