| 交流低压配电柜适用条件 Application conditions of AC low voltage distribution cabinet 1. 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℃。 1. ambient air temperature is not higher than +40 C, not less than -5 C, and the average temperature in 24h is not higher than +35 C. 2. 户内安装使用，使用地点的海拔高度不得超过2000m。 2. indoor installation and use. The height of the site should not exceed 2000m. 3. 周围空气相对湿度在最高温度为+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%,应考虑到由于温度的变化可能会偶然产生凝露的影响。 3. the relative humidity around the air is not more than 50% at the highest temperature of +40 C, allowing for relatively large relative humidity at lower temperatures, such as 90% at +20 C, which should be taken into consideration as the effect of temperature changes may occur by accidental condensation. 4. 设备安装时垂直面的倾斜度不超过5度。 4. when the equipment is installed, the inclination of the vertical surface should not exceed 5 degrees. 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。 5. equipment should be installed in areas where there is no severe vibration and impact, and places where electrical components are not sufficiently corroded. 6. 用户有特殊要求时可与制造厂协商解决。 6. users can negotiate with manufacturers when they have special requirements. |
