GSC2-NF系列机械联锁交流接触器的工作条件和安装条件
WORKING CONDITION AND INSTALLATION WAY △ 周围空气温度-5℃～+40℃，24小时的平均值不超过+35℃。
Ambient temperature: -5℃～+40℃. Average temperature ≤+3 5℃ in 24H;
△ 海拔高度：不超过2000m。 Elevation ≤2000m
△ 大气条件：安装地点的空气相对湿度在最高温度为+40℃时不超过50%，在较低 温度下可以有较高的相对湿度；最湿月的月平均最低温度不超过+25℃，该月的 月平均最大相对湿度不超过90%；并考虑因温度变化发生产品上的凝露；
Air condition: Relative humidity is not exceeding 50% at the maximum ambient temperature +40℃ . With lower temperature, higher humidity would be permitted. And average maximum relative humidity ≤90% in the most humidity month, at the same time, the average minimum temperature should ≤+25℃, and should give consideration to dews on the good surface, which would appear due to temperature change.
△ 产品应安装和使用在无显著摇动、冲击和振动的地方。
Contactor should be installed at no significant sharking or vibration place.
△ 安装方式：螺钉安装; Installation way: by screw
△ 安装类别为：“安装类别III”; Installation categories: class III
△ 污染等级为：“污染等级3”；Pollution grade: Grade 3
△ 安装角度：垂直安装，安装面与垂直面的倾斜度不大于±5°。
Installation gradient: vertical installed, the tilt gradient with vertical face should ≤±5°
GSC2-NF系列机械联锁交流接触器的使用注意事项 NOTICE
在使用过程中，机械联锁交流接触器的银触点，经过一定次数的接通和分断 操作后，银触点表面呈现烧毛或发黑现象，这不影响使用，不要锉平磨光，否则会降低触点使用寿命，若烧毛比较严重，影响接触时，可用油光锉轻轻锉光，
在银触头磨损到露出铜接触板之前仍可正常使用。
In operate procession, contactor's silver contact will appear black phenomenon after a certain number of making and breaking, which does not affect work, don't need file-polished, otherwise will reduce silver contact life. If appear serious black and impact contact, can be glossed shiny by nail, the silver contact can be normally used before exposing silver plate
