使用环境 /Use environment

● 周围空气温度不高于 + 40℃，不低于 -5℃，24h 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最高温度为 +40℃时不超过 50%，应在较低温度时允许有较大的相对温度 ( 例如 +20℃时为 90%) 考虑到由于温度的变化可能会
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；
● 用户有特殊要求时可与制造厂协商解决。
● The ambient air temperature is not higher than + 40℃ , not lower than -5℃ , the average temperature within 24 h shall not be higher than + 35 ℃ ;
● Indoor installation and use, the altitude of the place of use shall not exceed 2000m;
● The relative humidity of the surrounding air does not exceed 50% at the maximum temperature of +40℃ . It should allow a relatively large temperature
at a lower temperature (for example, 90% at +20℃ ). Considering that the temperature may change accidentally. Produce the effects of condensation;
● The inclination of the equipment when installed is not more than 5° with the vertical plane;
● The equipment should be installed in places where there is no severe vibration and shock, and where it is not enough to corrode electrical
components;
● Users can negotiate with the manufacturer if they have special requirements.
