During DCS maintenance,especially when touching hardware cards or communication components,take the following measures to prevent static electricity.

1.Keep the environment with a certain humidity.Especially in northern areas or in dry winter,the number of failures due to static electricity is far greater than in the southeast coastal areas or other seasons.Therefore,in some important places,such as computer rooms,laboratories,and electronic equipment installation workshops,it should be considered to maintain a certain The problem of humidity,especially for those closed air-conditioned rooms,should have certain humidity control equipment.

2.Lay anti-static floor,control room and operation room need to lay anti-static floor.

3.When maintaining the plug-in card or holding the card by hand,be sure to discharge static electricity from your hand first,and try to avoid touching the electronic components,panel circuits and solder joints of the card directly with your hands.

4.The card should be stored in an anti-static plastic container or an anti-static plastic bag,and stored in the card box.

5.When maintaining the system,you should also pay attention to wearing a DCS anti-static wrist.

DCS维护过程中特别是在触碰硬件卡件或通讯部件时应采取如下措施做好防静电。

1．保持环境有一定的湿度。特别北方地区或在干燥的冬季，因静电产生故障的事例要远远大于在东南沿海地区或其他季节，所以在一些重要场所，如计算机机房、实验室、电子仪器的装调车间应考虑保持一定湿度的问题，特别是对那些封闭形的空调房间，更应有一定控制湿度的设备。

2．铺设防静电地板，控制室和操作室均需铺设防静电地板。

3．在维护插扒卡件时或用手拿捏卡件时一定注意先对手释放静电，注意尽量避免用手直接触碰卡件电子元件、面板电路和焊点。

4.卡件应存放在防静电塑料盛放器或防静电塑料袋中，并存放在卡件盒中。

5．系统维护时还应注意佩带DCS防静电手腕。
