4.4
Requirements for the electrical connection
The Wallbox is approved exclusively for fixed installation and has no device for disconnection
from the mains. The national regulations and standards must be followed during installation
of the supply line. There is no integrated circuit breaker or residual current device; these must
be installed upstream. A Type A circuit breaker is generally sufficient due to the integrated DC
fault current monitoring.
Also note the regulations in place for upstream protection from transient overvoltages (e.g.
through lightning), for example, by using SPDs (Surge Protection Device) according to IEC
60364-7-722.
