4.Lub luag haujlwm tseem ceeb ntawm tus lej
(1) Ua raws li cov cim: xyuas kom cov xov hlau ua raws li VDE / DIN cov qauv thiab ua tau raws li cov kev cai ntawm kev nyab xeeb hluav taws xob ntawm lub teb chaws Yelemees thiab European Union (xws li daim ntawv pov thawj CE)
(2) Kev txheeb xyuas qhov ua tau zoo: Cov yam ntxwv tseem ceeb xws li qhov hluav taws xob, cov khoom siv, thiab kev hloov pauv tuaj yeem txiav txim ncaj qha los ntawm tus lej, ua kom yooj yim xaiv cov qauv.
(3) Daim ntawv thov scenario txuam: Cov lej sib txawv sib haum rau qhov chaw siv tau ruaj khov (xws li tsis tshua muaj siab / siab siab, kub / pa, ruaj / txawb)
Tus naj npawb ntawm cov xaim hluav taws xob hauv lub teb chaws Yelemees yog nyob nruab nrab ntawm VDE tus qauv. Los ntawm kev sib xyaw ua ke ntawm "prefix (tus qauv txheej txheem) + tus lej (voltage) + tsab ntawv (khoom siv / qauv)", qhov kev ua tau zoo ntawm cov xov hlau tau pom meej meej. Kev paub txog txoj cai no tuaj yeem txiav txim siab sai sai rau cov xwm txheej siv tau ntawm cov xov hlau, uas yog qhov tseem ceeb tshwj xeeb hauv kev xaiv cov khoom lag luam, cov khoom siv hluav taws xob hauv tsheb, siab - qhov kub thiab txias thiab lwm qhov chaw.
