1. Kev nyab xeeb qib UL thiab IEC cov qauv kev nyab xeeb feem ntau siv tau rau cov ntawv pov thawj thiab tsim qauv. UL thiab IEC muaj cov qauv sib txawv thiab cov kev cai uas lub davhlau ya nyob twg thaiv yuav tsum tau ua. Yog li ntawd, nws yog ib qho tseem ceeb heev kom nkag siab txog tag nrho cov txheej txheem kev nyab xeeb kom ntseeg tau tias tus nqi ntsuas ntawm lub davhlau ya nyob twg ua tau raws li cov cai no. Cov khoom ntawm lub davhlau ya nyob twg thaiv ntawm lub connector muaj ib tug flammability theem raws li UL94V-0.
2. Kev ntsuas tam sim no thiab qhov ntsuas hluav taws xob: xaiv lub davhlau ya nyob twg nrog qhov ntsuas tsawg kawg 150 feem pua ntawm qhov xav tau siab tshaj plaws tam sim no ntawm lub cev, thiab qhov ntsuas hluav taws xob qis qis dua qhov siv qhov siab tshaj qhov ntsuas hluav taws xob, thiab tseem xav txog qhov hluav taws xob hluav taws xob hauv qhov system. .
3. Kev ua haujlwm tau zoo ntawm lub davhlau ya nyob twg thaiv kom muaj kev nyab xeeb ntawm tus neeg teb xov tooj los ntawm kev muab kev sib txuas zoo yam tsis muaj cov xov hlau lossis cov terminals. Lawv yog cov ruaj khov heev thiab tsim kom muaj kev sib haum xeeb hauv kev lag luam tswj vaj huam sib luag.
4. Kev tsim kho kev tsim kho tuaj yeem sib xyaw cov xim vaj tsev sib txawv lossis cov cim cim kom yooj yim txheeb xyuas ntau yam kev sib txuas ntawm lub davhlau ya nyob twg, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem nyuaj uas muaj ntau txoj hlua hluav taws xob thiab cov kab hluav taws xob hauv qhov chaw nruab nrab.
5. Muaj peb txoj hauv kev los kho cov kab nkag thiab xaim ntawm lub davhlau ya nyob twg txuas. Cov kab lus uas tuaj yeem yog kab rov tav (90 degree), ntsug (180 degree) thiab 45 degree. Peb txoj kev kho cov hlau tseem ceeb yog ntsia hlau davhlau ya nyob twg, khawm thiab thawb rau hauv.
