3. IEC thiab AS daim ntawv pov thawj

Lwm qhov yuav tsum tau xav txog yog paub txog IEC thiab AS daim ntawv pov thawj.Yog tias DC disconnect hloov chaw tsim khoom muaj cov ntawv pov thawj no, nws txhais tau tias lub tuam txhab ua raws li cov lus qhia thoob ntiaj teb thaum tsim PV DC disconnect hloov khoom.

Piv txwv li, nyob rau hauv thawj feem ntawm EIC 60204-1: 2016, cov chaw tsim tshuaj paus yuav tsum tau muab manually ua manually disconnect keyboards rau txhua lub ntsiab lub hwj chim qhov chaw raug ntsia nrog rau tshwj xeeb tsim tsis.

4. Txoj kev teeb tsa

Koj tseem yuav tau xav txog qhov chaw nyiam rau mounting DC disconnect hloov thiab mounting style uas tsim nyog rau koj daim ntawv thov.Cov style feem ntau yog plaub-qhov mount, tsim nyob rau hauv ib tug square qauv nrog plaub lub qhov taub nyob rau hauv txhua lub ces kaum.Qhov style no zoo tagnrho yog tias koj npaj siab yuav mount qhov hloov ntawm qhov chaw tiaj tus, raws li nws tso cai rau qhov hloov mus ua kom nrawm li sai tau.

Nta ntawm Slocable PV DC disconnect hloov:
