1) Imirongo ya kabili yashizweho igomba gukorerwa igenzura ryokwemererwa hamwe nuburyo bwuzuye bwo kubyemera mbere yuko bishyirwa mubikorwa.
) Kurwanya insulasiyo ntibigomba kugabanukaho 30% ugereranije nubushakashatsi bwabanje (ku bushyuhe bumwe). Bitabaye ibyo, DC ishobora kwihanganira ikizamini cya voltage. Ku nsinga zahuye n’amashanyarazi mu gihe kirenze ukwezi ariko munsi yumwaka umwe, DC ihanganira ikizamini cya voltage kigomba gukorwa kuri kimwe cya kabiri cyumubyigano wikizamini.
3) Ku nsinga zifite re - zihererekanyabubasha, umuhuza hagati, cyangwa uhuza mushya hagati, umwanya wicyiciro ugomba kugenzurwa, kurwanya insulasiyo bigomba gupimwa na megohmmeter, kandi hagomba gukorwa ikizamini cya voltage. Gusa nyuma y'ibizamini byose byatsinzwe birashobora kwemererwa gukomeza gukora.
