Ua ntej ntawm tag nrho cov, yam xws li ambient kub, av noo, plua plav, pH, corrosive gases, thiab lwm yam yuav tsum tau txiav txim siab, thiab cov qauv kev tiv thaiv ntawm lub hwj chim mov yuav tsum tau yoog rau nws installation ib puag ncig. Qhov no muaj kev sib raug zoo nrog kev ua haujlwm ntev, kev nyab xeeb thiab txhim khu kev qha ntawm cov khoom siv hluav taws xob.
Thib ob, xaiv ib lub hom phiaj thiab lub hwj huam mov nrog lav zoo. Lub hom thiab qhov zoo ntawm DC tswj fais fab mov tuaj yeem hais tau tias yog kev sib tshuam. Lub hom yog qhov lav ntawm cov khoom zoo, yog li tom qab xaiv lub hwj huam mov nrog lub hom kom zoo dua, nws yog qhov kev xaiv. Kev ua tau zoo, yog li tsis tsuas yog tuaj yeem tiv thaiv lawv txoj cai thiab kev txaus siab raws li cov neeg siv khoom, tab sis kuj lav lub neej kev pab cuam thiab kev ua tau zoo ntawm cov khoom siv hluav taws xob hauv ib daim ntawv.
Ntxiv dua thiab, xaiv cov khoom siv hluav taws xob nrog kev pab cuam tom qab muag. Yog tias muaj teeb meem nrog cov khoom siv fais fab, qhov tseem ceeb ntawm kev pab cuam tom qab muag tau tshwm sim.
Thaum xaiv cov khoom siv hluav taws xob (hom hluav taws xob), koj yuav tsum tau them sai sai rau cov khoom siv hluav taws xob input voltage, zaus, tso zis hluav taws xob, cov yam ntxwv thauj khoom, thiab lwm yam. Tsis tas li ntawd, nws tseem yuav tsum tau txiav txim siab qhov sib txuam ntawm cov khoom siv hluav taws xob thiab lub cev muaj zog sib xws, txhawm rau muab kev ua si tag nrho rau lub zog txuag thiab kev ruaj ntseg zoo ntawm cov khoom siv hluav taws xob thiab ib-theem fais fab mov, thiab xyuas kom meej tias cov khoom siv ua haujlwm.
