使用条件 / Conditions of Use

● 周围空气温度不高于 +40℃，不低于 -5℃，并且 24h 平均温度不高于 +35℃；
● 周围空气清洁，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高的相对湿度，例如 +25℃时为 90%，但应考虑到由于温度变化
可能会偶然产生适度的凝露；
● 户内使用，海拔高度不超过 2000m；
● 在无显著摇动和冲击震动的地方；
● 污染等级：3 级；
● 抗震烈度：8 级；
● 开关柜运输和储存过程中的温度可在 -25℃至 55℃范围之间，在短时间内（不超过 24h）温度可达到 +70℃；
● 若上述使用条件不能满足时，应由用户和制造厂协商解决。
● The ambient air temperature is not higher than +40℃ , not lower than -5℃ , and the average temperature of 24 h is not higher than +35℃ ;
● The surrounding air is clean, the relative humidity is not more than 50% at the highest temperature of +40℃ , and the higher relative
humidity is allowed at lower temperatures, for example, 90% at +25℃ , but it should be considered due to temperature changes.
Occasionally produces moderate condensation;
● Indoor use, the altitude does not exceed 2000m;
● in places where there is no significant shaking or shock;
● Pollution level: 3;
● Seismic intensity: 8 levels;
● The temperature during the transportation and storage of the switchgear can be between -25℃ and 55℃ , and the temperature can reach
+70℃ in a short time (not more than 24h);
● If the above conditions of use cannot be met, it should be resolved by the user and the manufacturer.
