Ukulawula Ukugcinwa KweKhabhinethi

1. Nqamula ukunikezwa kwamandla futhi uhlole ukuthi ifreyimu yekhabhinethi yokulawula isekelwe ngokuthembekile, uqinisekisa ukuthi ukumelana nomhlaba akungaphezu kuka-4Ω.
2. Ikhabethe lokulawula lisebenza ngama-voltage ahlukene (110V DC; 220V AC single-isigaba; ezintathu-isigaba AC). Ngesikhathi sokulungiswa, amasekhethi kufanele ahlukaniswe ngokucacile ukuze kunqandwe izingozi ezimfushane-zezifunda.
3. Wonke amaswishi kagesi ekhabhinethi yokulawula kufanele asebenze kahle nangokwethembeka, ngaphandle komsindo obonakalayo. Izixhumi zekhebula namabhulokhi etheminali akumele zixege, futhi izintambo ezixhunyweni lwekhebula lokuxhumana elinyakazayo akumele zinqanyulwe.
4. Sebenzisa ibhulashi elithambile noma umshini wokomisa izinwele ukuze ususe uthuli okufakwayo kwephaneli kanye nazo zonke izingxenye zokushintshwa kwe-electromagnetic switch. Futhi, hlola isimo soxhumana nabo be-switch kagesi ngaphakathi kwekhabhinethi yokulawula, isimo sokuxhumana, ukufakwa kwekhoyili, nokusebenza okuthembekile kwezingxenye zemishini.
5. Uma ushintsha ama-fuses, qinisekisa ukuthi i-breaking current ifana ne-current of the circuit.
