Isifinyezo
Idivayisi Evikelayo Yochungechunge lwe-TU2 ifanelekela ukusatshalaliswa kwamandla nokulawulwal uhlelo olune-AC I-50Hz kanye ne-voltage ekalwe yi-230V/400V. Ihlangabezana nezidingo zokuhlola ze-ll ze-SPD, isetshenziselwa ukucindezela idivayisi yomthelela we-overvoltage yesikhashana, ekhipha amandla okukhuphuka, ngaleyo ndlela ivikele isekethe yesistimu kanye nemishini.
Idivayisi Yokuvikela Yochungechunge lwe-TU2 ifanelekela ukuhlanganiswa okuhlukanisiwe, kanye nokuqaphela ukuhlukaniswa uhlelo lokuvikela (isigaba 1, 2 noma 3), ukuze uhlelo lokusabalalisa amandla kagesi aphansi lube lukhulu kakhulu futhi kuvikelwe kangcono.
Ibanga elifanele
I-TU2 SPD ngokuvamile ixhunywe ngokulingana engxenyeni engaphambili yemishini yesekethe evikelwe edingekayo eduze ngangokunokwenzeka kwe-down circuit teminal. I-SPD ixhunywe nokuphela komqhubi wesekethe (umugqa wesigaba L noma umugqa ongathathi hlangothi N), kanye nokuphela kokuhlangana.lukufakwa kwemishini phansiviqhwa lokuxhumanisa i-equipotential yombani.
