正常使用环境 Normal operating environment

◇ 周围空气温度不高于 +40℃，不低于 -5℃。24h 以内的平均温度不得高于 +35℃。 

◇ 户内安装使用，使用地点的海拔高度不得超过 2000m。 

◇ 周围空气相对湿度在较高温度为 +40℃时不超过 50％，在较低温度时允许有较大的相对湿度。( 例如 +20℃时为 90％ ) 应考虑到由于温度变化可能会偶然产生凝露的影响。 

◇ 设备安装时与垂直面的倾斜度不超过 5°。 

◇ 设备应安装在无剧烈震动和冲击的地方，以及不足以使电器元件受到腐蚀的场所。 

◇ 用户有特别要求时与制造厂协商解决。 

◇ 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.
