I-electro-mechanical ngokwemvelo.Okugqamayo lapha ukuthi:
1.Ingenziwa ngezintambo kunoma iyiphi indlela.
2.Ivumelana ne-IEC/EN 61008-1 (i-RCCB yama-mains voltage ezimele), Ihambisana nokukhululwa kwe-electro-mechanical esebenza ngokuphepha ngisho nangaphandle kwe-voltage yokuhlinzeka noma i-voltage yolayini engaphansi kuka-50V.
3.Uhlobo -A: Ivikela ezinhlotsheni ezikhethekile ze-DC edonsayo eyinsalela engakalungiswa.
4.Ukuvikelwa kwabantu ngokumelene nokushaqeka kukagesi ngokuthintana ngqo (30 mA).
5.Ukuvikelwa kwabantu ngokumelene nokushaqeka kukagesi ngokuthintana ngokungaqondile (300 mA).
6.Ukuvikelwa kokufakwa ezingozini zomlilo (300 mA).
7. Ihlinzeka ngokuvikeleka okuphelele ezinhlelweni zokusabalalisa zasendlini nezohwebo.
