如果維護(hù)不注意，靜電可能對(duì)DCS卡件或通訊帶來(lái)不小影響，DCS維護(hù)過(guò)程中特別是在觸碰硬件卡件或通訊部件時(shí)應(yīng)采取如下措施做好防靜電。?
1．保持環(huán)境有一定的濕度。特別北方地區(qū)或在干燥的冬季，因靜電產(chǎn)生故障的事例要遠(yuǎn)遠(yuǎn)大于在東南沿海地區(qū)或其他季節(jié)，所以在一些重要場(chǎng)所，如計(jì)算機(jī)機(jī)房、實(shí)驗(yàn)室、電子儀器的裝調(diào)車間應(yīng)考慮保持一定濕度的問(wèn)題，特別是對(duì)那些封閉形的空調(diào)房間，更應(yīng)有一定控制濕度的設(shè)備。?
2．鋪設(shè)防靜電地板，控制室和操作室均需鋪設(shè)防靜電地板。?
3．在維護(hù)插扒卡件時(shí)或用手拿捏卡件時(shí)一定注意先對(duì)手釋放靜電，注意盡量避免用手直接觸碰卡件電子元件、面板電路和焊點(diǎn)。
4.卡件應(yīng)存放在防靜電塑料盛放器或防靜電塑料袋中，并存放在卡件盒中。?
5．系統(tǒng)維護(hù)時(shí)還應(yīng)注意佩帶DCS防靜電手腕。PP2579 Frequenzumricht?er Platine board Demag ETAS1-C01
