Normal working conditions:

1. The ambient air temperature is: the limit temperature is - 35 ° C ~ + 70 ° C, the normal working temperature is - 5 ° C ~ + 40 ° C, the average value within 24 hours does not exceed + 35 ° C, if it is not used in the normal working range, it needs to reduce the capacity when it exceeds + 40 ° C.
2. Altitude: no more than 2000m.
3. Atmospheric conditions: the relative humidity of the air at the installation site shall not exceed 50% at + 40 ° C. higher relative humidity can be allowed at lower temperature, such as 90% at 20 ° C. special measures shall be taken for occasional condensation due to temperature change.
4. Pollution level: 3.
5. Installation category: III.
6. Enclosure protection grade: IP20.
7. Installation conditions: the inclination between the installation surface and the vertical is not more than ± 5 °.
8. Shock and vibration: the contactor shall be installed and used in the place without obvious shaking, impact and vibration.
9. Transportation and storage: contactors shall not be subjected to severe collision and vibration during transportation, and shall not be attacked by rain and snow during transportation and storage. The contactor is suitable for transportation and storage at temperatures between - 25 ° C and + 55 ° C and up to + 70 ° C in a short time (within 24 h).
