◇ 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℃ .
◇ For indoor installation and use, the altitude of the place of use shall not exceed 2000m m.
◇ The relative humidity of ambient air shall not exceed 50% at the highest temperature of +40℃ , and a larger relative humidity is allowed at the lower temperature. (for example, 90% at +20℃ ) consideration should be given to the effect that condensation may occasionally occur due to temperature changes.
◇ When the equipment is installed, the inclination to the vertical plane shall not exceed 5.
◇ The equipment shall be installed in places free from severe vibration and impact, and places insufficient to corrode electrical components.
◇ When users have special requirements, negotiate with the manufacturer to solve them.
