1.全部元器(qi)件(jian)(jian)應依照其生產制造(zao)(zao)要求(qiu)的安裝應用標準開展安裝應用,其坡(po)度(du)不超5°,務必確保電氣設備(bei)的飛弧對作業(ye)者以及(ji)他元器(qi)件(jian)(jian)不造(zao)(zao)成傷害,手動式實際(ji)操作的元器(qi)件(jian)(jian),實際(ji)操作組織應靈便,無(wu)卡阻(zu)狀況。
2.大連高低壓開關柜產(chan)品上的全部顯示燈(deng)和按鍵規(gui)格型號顏色(se)應合乎電路原(yuan)理圖(tu)或接線方法的要(yao)求(qiu)。
3.元器件務必選用獲得強制產(chan)(chan)(chan)品認(ren)證(zheng)(zheng)的廠家生產(chan)(chan)(chan)的達標產(chan)(chan)(chan)品,非(fei)認(ren)證(zheng)(zheng)產(chan)(chan)(chan)品不(bu)可應(ying)用。
4.大連高低(di)壓(ya)開關(guan)柜(ju)產(chan)品(pin)內挑(tiao)(tiao)選的(de)(de)(de)電氣元器件(jian)(jian)和原材(cai)料,務必合乎認(ren)(ren)證產(chan)品(pin)規(gui)定和消費(fei)者(zhe)工程圖紙(zhi)的(de)(de)(de)規(gui)定,不(bu)在危害產(chan)品(pin)本質品(pin)質規(gui)定的(de)(de)(de)前(qian)提條件(jian)(jian)下,能夠 征求(qiu)有關(guan)準許開展認(ren)(ren)證要求(qiu)范(fan)疇內的(de)(de)(de)代用。但(dan)同批成套設備產(chan)品(pin)的(de)(de)(de)同一(yi)型號規(gui)格元器件(jian)(jian)應挑(tiao)(tiao)選同一(yi)生產(chan)廠家。
