· Ingaboshelwa/ikululwe kuloliwe we-DIN, isisekelo nomnyango
· Izesekeli zokufaka ezifakwe ekhadini

Isakhiwo esisha esinamandla, esivalwa ngokushesha nangokushesha kwezici zokusebenza kanye nokuxhumana kwekhefu eliphindwe kabili, sithuthukisa kakhulu ukusebenza kweswishi.
Uchungechunge olusha lwe-WNW lunikeza isilinganiso samandla esiphezulu kakhulu emakethe, esinomshini wokushisisa ofanayo emoyeni wamahhala nasezindaweni ezivalekile, okuqeda isidingo sokwehlisa futhi ngaphandle kokwandisa indawo yokufaka.
Kuwo wonke ama-voltage, aze afike ku-690V, i-WNWisinqamuleliingahlinzeka ngesilinganiso samanje se-AC-23A esiphelele

WNWisinqamuleliingafakwa ivundlile noma ibheke phezulu, noma ifakwe nophahla. I-engeli yokukhweza yeswishi igxilile phezulu nasohlangothini lweswishi.
Uchungechunge olusha lokushintshwa kwe-isolation lusebenza kangcono ukuhlangabezana nezidingo zokuzihlukanisa kanye ne-insulation.
