Design the supply cable in accordance with the wallbox’s technical data (
) and observe the following local conditions:
- Cable length, cross-section and cable type
- Type of routing and cable coverings
NOTE
Installing the wallbox in a supply network in which sources of interference (e.g. a fre-
quency inverter) are operated may result in malfunctions or termination of the charging
process.
Residual current device
The required residual current device must be located in the house installation (in accord-
ance with IEC 60364-7-722 [in Germany in accordance with DIN VDE 0100-722]).
■
The wallbox has a residual current sensor for DC residual current monitoring > 6 mA
with activation behaviour in accordance with IEC 62955.
■
The wallbox must be individually protected with at least one type A residual current
device.
■
No other circuits may be connected to the residual current device.
■
It is essential that national regulations are observed.
Line circuit breaker
■
The line circuit breaker required must be located in the house installation.
■
The wallbox must be protected with a line circuit breaker of max. 20 A with C character-
istics.
■
The line circuit breaker must be dimensioned in accordance with the national regula-
tions, taking into account the type plate, desired charging power and supply cable
(cable length, cross-section) to the wallbox.
■
One line circuit breaker is required per charging point.
