Critical to ensure complete isolation between devices and tensions connected to relay contacts, because they are outside the voltage and the device eHouse system and relay contacts and are part of the electrical system (230V), rather than electronic low voltage installation eHouse home .
Kritikal upang matiyak ang kumpletong paghihiwalay sa pagitan ng aparato at tensions na konektado sa mga relay contact, dahil ang mga ito ay sa labas ng boltahe at ang sistema eHouse aparato at mga contact ng relay at bahagi ng electrical system (230V), kaysa sa electronic na mababa boltahe-install eHouse bahay .
