目前UPS電源所用的蓄電池一般都是免維護(hù)的密封鉛酸電池，設(shè)計(jì)壽命普遍是5年。UPS電源不宜側(cè)放，應(yīng)保持進(jìn)風(fēng)孔與出風(fēng)孔通暢;負(fù)載與UPS電源連接時(shí)，須先關(guān)閉負(fù)載、再接線，然后逐個(gè)打開(kāi)負(fù)載，嚴(yán)禁將電動(dòng)、復(fù)印機(jī)等感性負(fù)載接入U(xiǎn)PS電源，以免造成傷害。將UPS電源接到**的帶有過(guò)電流保護(hù)裝置的插座上時(shí)，所用電源插座應(yīng)接保護(hù)地端;無(wú)論輸入電源線是否插入市電插座，UPS電源輸出都可能帶電。要使UPS電源無(wú)輸出，須先關(guān)掉開(kāi)關(guān)，再取消市電供應(yīng)。11、UPS電源正確安裝注意事項(xiàng)：在給UPS連接輸出電源時(shí)還應(yīng)該注意安全，由于UPS的輸出電壓和電流都比較大，所以在連接輸出電源時(shí)還要注意安全防止觸電***的發(fā)生。更換電池時(shí)先關(guān)閉UPS電源并脫離市電，使用帶絕緣手柄的螺絲刀，不要將工具或其它金屬物品放在電池上。連接電池線時(shí)，在接頭處出現(xiàn)細(xì)小火花屬正?，F(xiàn)象，不會(huì)對(duì)人身安全及UPS電源造成危害，千萬(wàn)不要將蓄電池正負(fù)極短接或反接。更換蓄電池時(shí)，不宜個(gè)別更換，比較好整體更換。另外禁止將不同安培數(shù)、不同品牌的電池組合使用。12、定期維護(hù)：這是針對(duì)UPS電源里面的蓄電池的，作為UPS電源里面的**元器件，我們更應(yīng)該認(rèn)真保護(hù)，要定期維護(hù)，如果當(dāng)?shù)亻L(zhǎng)期不停電，必須定期。南昌UL33-1000L不間斷電源ups維修在哪里南昌穎頓科技有限公司提倡終身學(xué)習(xí)，拒絕惰性。</p><div
