Dongosolo lolamulira lamotaIli ndi ma switch, ma fuse, ma contactor akuluakulu ndi othandizira, ma relay, kutentha, zida zoyendetsera magetsi, ndi zina zotero, zomwe ndi zovuta kwambiri. Pali mitundu yambiri ya zolakwika, ndipo nthawi zambiri zimakhala zofunikira kusanthula ndi kuthetsa mavuto pogwiritsa ntchito ma diagram owongolera.
Kawirikawiri, muyenera kusamala kuti mkati ndi kunja kwa bokosi lowongolera zinthu zikhale zoyera komanso zouma, popanda madzi kapena mafuta. Nthawi zonse (mlungu uliwonse) gwiritsani ntchito fani yaying'ono kuti muchotse fumbi pazida ndi ma terminal ndi mizere m'bokosilo, kapena gwiritsani ntchito burashi yoviikidwa mu chotsukira chamagetsi kuti muwatsuke, kuti musakhudze ntchito kapena kutenthetsa kwa contactor ndi relay. Pa mabokosi owongolera okhala ndi zotsutsa zowuma, nthawi zambiri musazimitse chotenthetsera nthawi iliyonse mukafuna. Bokosilo liyeneranso kukhazikika pansi kuti lipewe kugwedezeka kwamagetsi.
Yang'anani kulimba kwa mawaya ndi zomangira m'bokosi nthawi zonse (mwezi uliwonse) kuti mawaya ndi zomangira zisamasuke. Yang'anani ngati zinthu monga ma switch, contactors, relay, ndi zina zotero zawonongeka kapena zapsa, komanso ngati momwe gawo lililonse limagwirira ntchito komanso ntchito zoyambira, zoyimitsa, ndi zolumikizirana zilili bwino. Sungani zolumikizira zoyenda komanso zosasinthasintha za contactor zitatsekedwa komanso zili bwino kuti mota isapse chifukwa cha kukhudzana koipa. Ngati pamwamba pa contact pali bwino ndipo padangokhala lakuda, mutha kupukuta ndi nsalu yolimba. Musapukute mosavuta gawo la alloy losagwira kutentha pamwamba, apo ayi lidzafupikitsa moyo wa contact; Ngati pamwamba pa cholumikizira chatsekedwa kwambiri, mungagwiritse ntchito sandpaper ya “0″ kuti muisunthe. Zolumikizira zoyenda ndi zosakhazikika ziyenera kusunga kulumikizana kwa mzere kapena pamwamba, osati kulumikizana kwa mfundo. Mkhalidwe wa cholumikizira ukhoza kuwonedwa poyika pepala pakati pa zolumikizira zoyenda ndi zosakhazikika. Ngati sichinalumikizidwe mwamphamvu chikakokedwa, zikutanthauza kuti cholumikizira kapena kasupe ayenera kusinthidwa kapena kusinthidwa. Mfundo iyi iyenera kuganiziridwa mozama. Muzochitika zofatsa, kukhudzana koyipa kungapangitse kukana kwakukulu kwa kukhudzana (magetsi), zomwe zikutanthauza kuti katunduyo akuwonjezeka, zomwe zimapangitsa kuti relay yoteteza kwambiri igwe. Muzochitika zoopsa, zimapangitsa kuti mota iziyenda mopanda gawo ndikuyaka.
Mukasintha ma relay ndi ma contactor, muyenera kusamala ndi mphamvu yamagetsi yogwira ntchito ya coil yamagetsi kuti mupewe kuyatsa coil chifukwa chosasinthidwa bwino. Kawirikawiri, pali 24V, 220V ndi 380V. Pa ma relay a nthawi, kuwonjezera pa kusamala zofunikira za mphamvu ya coil, muyeneranso kufotokozera bwino gawo losinthira nthawi (ola, mphindi, sekondi) ndi kutalika kwa nthawi yotumizira; ngati mphamvu yosinthira ya thermal relay ndi yoyenera komanso yoyenera.
Pa ma mota omwe amayatsidwa pogwiritsa ntchito njira ya star-delta (Y-△) (kuchedwa kwa kusintha kwa masekondi 5), onani ngati kuyamba kwa kusintha kuli koyenera. Nthawi zambiri, opanga amakhala ndi malamulo okhwima pa kayendedwe koyambira kwa mota (monga kuchuluka kwa kuyamba pa mphindi), ndipo padzakhala zilembo zochenjeza pa bokosi loyambira kuti zikumbutse ogwiritsa ntchito kuti apewe kuwonongeka kwa mota chifukwa choyambira pafupipafupi. Nthawi yomweyo, ndikuletsanso zida zina zamagetsi zomwe zili mu bokosi loyambira (monga ma reactor oyambira, ndi zina zotero) kuti zisatenthe ndi kuyaka. Chifukwa chake, pamakina owongolera magalimoto omwe amayamba ndikuyima pafupipafupi kapena omwe ali ndi mafunde akuluakulu, kayendedwe kowunikira ndi kukonza kuyenera kufupikitsidwa. Yang'anani nthawi zonse ntchito yoteteza kutentha kwambiri (mutha kutembenuza makina ofiira ang'onoang'ono pafupi nawo) ndipo mtengo wake wokhazikika suyenera kupitirira mtengo wamakono womwe uli pa dzina la mota kuti muwonetsetse kuti ungathe kuchita gawo loteteza overload.
