1. The ambient air temperature is not higher than +40℃ and not lower than -5℃. The average temperature within 24 hours shall not be higher than +35℃. 2. For indoor installation and use, the altitude of the place of use shall not exceed 2000m. 3. The relative humidity of the surrounding air does not exceed 50% when the highest temperature is +40℃, and a higher relative humidity is allowed at a lower temperature: (for example, 90% at +20℃), it should be considered that the temperature may change Accidental impact of condensation. 4. When the equipment is installed, the inclination from the vertical plane should not exceed 5°. 5. The equipment should be installed in places where there is no severe vibration and impact, and places where electrical components are not corroded. 6. When the user has special requirements, it can be resolved through consultation with the manufacturer.
