Working environment
- The ambient air temperature is not higher than +40℃, not lower than -5℃, and its average temperature within 24h is not higher than +35℃.
- Atmospheric conditions, clean air, relative humidity do not exceed 50% when the highest temperature is +40℃, higher relative humidity is allowed at lower temperatures, for example 90% at +20℃, but temperature changes should be taken into consideration , It is possible to occasionally produce moderate condensation.
- The altitude does not exceed 2000m.
