Kana iyo EVSE yaiswa munzvimbo yekupaka, uye ndokupihwa netambo yemagetsi yepasi pevhu:

imwe neimwe EVSE ichave yakashongedzwa netsvimbo yekuvhuvhuta.
yega yega EVSE ichave yakabatana kune equipotential network. Iyi samambure inofanirwa zvakare kuve yakabatana neiyo chivakwa equipotential network.
gadza mhando 2 SPD mune yega EVSE
Rudzi rwe3 SPD inokurudzirwawo kune iyo Load Management System (LMS) semagetsi emagetsi. Iyi mhando 3 SPD inofanirwa kuiswa pasi zasi mhando 2 SPD (iyo inowanzo kukurudzirwa kana kudiwa mune switchboard uko iyo LMS yakaiswa).

Chivako chikuru chakagadzirirwa tsvimbo yemheni (systemning protection system) kuchengetedza chivakwa.

Mune ino kesi:
