I-S7 surgace boxes short circuit kanye nemisebenzi yokuvikela ukugcwala ngokweqile, futhi isetshenziswa ohlelweni lokusabalalisa izibani zezimboni, ezentengiselwano kanye nezindawo zokuhlala. Futhi banezinzuzo zezinga eliphezulu lokuvikela (kufika ku-IP20), umthamo wokuphuka okuphezulu, isenzo esithembekile nesibucayi, ukunethezeka, ukufakwa kwezigxobo eziningi, impilo ende yesevisi, njll. I-Single pole ifaneleka kakhulu umjikelezo we-50Hz no-240V AC; izigxobo ezimbili, ezintathu nezine zilungele umjikelezo we-50Hz no-415V ukuvikela ukugcwala nokujikeleza okufushane. Zibuye zisetshenziselwe ukuvula noma ukuvala izinto zokusebenza zikagesi namasekhethi okukhanyisa ngaphansi kwezimo ezijwayelekile.
