37、接地螺絲因機櫃本體與底座間有膠皮形成絕緣，屏蔽地匯流排與底座間絕緣，現場控制站按規定做好接地處理。即分別接至現場控制站接地匯流排上。I/O櫃的電源地與UPS的電源地接至同一個地，保證等電位。2.各個硬件設備操作員站、工程師站、網絡交換機、服務器主機、係統顯示器等採用外殼接地或直接將電源地線連接至電氣接地網。3.I/O組件模擬量模件的40端即直流24伏的負端接至邏輯地匯流排上，邏輯地匯流排接至屏蔽地，再接入總接地匯流排。4.屏蔽地現場控制站的保護地應從機櫃下方的接地螺釘接至接地分幹線,現場控制站的屏蔽地應從接地匯流排接至公共連接板。5.接地電阻測試接地係統的電阻進行測試，以保證接地能滿足控制係統制造商的要求。1用電儀表的外殼、儀表盤、櫃、箱、盒和電纜槽 、保護管、支架、底座等正常不帶電的金屬部分，由於絕緣破壞而有可能帶危險電壓者，均應做保護接地。對於供電電壓不高於36V的就地儀表、開關等，當設計文件無特殊要求時，可不做保護接地。
