Normal Working and Installation Conditions

1. Ambient temperature: -5℃~+40℃, the average value should not exceed +35℃ within 24 hours.

2. Altitude: <2000m.

3. Atmospheric conditions: When the temperature reaches 40℃, the relative humidity of atmosphere should be <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 if there is occurrence of dews due to temperature changes.

4. Class of pollution: Class 3

5. Installation category. Ⅲ

6. Installation conditions: The inclination degree between the installation surface and the vertical surface does not exceed ±5°.

7. Impact shock: AC contactors should be installed and used in the place where there are no strong shakes and impacts.
