General safety information.
Please pay attention to the following points:
> Read this manual carefully.
> Heed all warnings.
> Follow all instructions.
> The smart Wallbox is available with a range of country-specific specifications. Please use the iden-
tification on the product label located on the underside of the wallbox to check whether the wallbox
has been approved to be installed and operated in your country.
> The wallbox must be installed, connected and approved for operation according to local rules and
regulations by a qualified specialist electrical contractor.
> The wallbox does not contain a residual current circuit breaker (RCCB). It must be installed in the
upstream power supply and exclusive to the supply cable for the wallbox. The smart Wallbox model
variant described in this document has an integrated DC fault current protection for which an RCCB
with Type A tripping characteristic is generally sufficient. However, country-specific and local reg-
ulations must always be observed. These may prescribe an RCCB with a different tripping charac-
teristic (e.g. Type B).
