Installation
Live installation of wiring is strictly prohibited!
The electricity meter shall be installed indoors as far as
possible. Special instrument box protection shall be used for
outdoor installation. The installation bottom plate shall be fixed
on the wall with strong fire resistance and not easy to vibration.
