Waya:
Kebul na gefen firikwensin (haɗa firikwensin / kwandishan sigina zuwa GSI127) yakamata a yi amfani da ruɓaɓɓen murɗaɗɗen garkuwa kuma a kore su daga igiyoyi masu ƙarfi.
Hakanan yakamata layukan siginar fitarwa na gefen sa ido suyi amfani da kebul mai kariya, wanda aka haɗa zuwa tashoshin shigar da wutar lantarki mai ƙarfi na tsarin sa ido.
Ya kamata garkuwar kebul ɗin ta kasance ƙasa a wuri ɗaya, yawanci a ƙarshen firikwensin ko ƙarshen sigina. A ƙarshen GSI127, garkuwar bai kamata a haɗa shi da naúrar ba don ingantacciyar amo.
Haɗin kai: Yi amfani da tashoshi masu toshewa: kammala duk wayoyi da farko, sannan toshe shingen tashar zuwa jikin na'urar, wanda ya dace sosai don gyarawa da kiyayewa.
Grounding: Bi ƙa'idodin tsarin da suka dace don tsarin ƙasa. GSI127 kanta baya buƙatar haɗin haɗin ƙasa.
