3.2 Specifications for the electrical connection
3.2.1 General
The charging station is set to 10 amps in the delivery state. Set the maximum current using the DIP
switches to match the installed line circuit breaker (see Chapter "↪ 4.6 DIP switch settings [31]").
The power supply line must be hardwired to an existing domestic installation and correspond to the nation-
ally applicable legal conditions.
Selection of the residual-current device (RCD):
● Every charging station must be connected via its own RCD. No other circuits may be connected to this
RCD.
● Residual-current device of at least type A (30 mA triggering current).
If the vehicles to be charged are not known (e.g. semi-public area), measures must be taken for protec-
tion where DC residual currents (>6 mA) occur. This can be realized, for example, through device ver-
sion KC-P30-xxxxxxx2, the use of an RCD type specifically intended for electric vehicles or with a RCD
type B. The vehicle manufacturer specifications must also be observed.
● If a charging station is protected with a type B residual-current device, every upstream residual-current
device, even those not assigned to the charging station, must either be type B or equipped with a DC
residual-current detection device.
● The nominal current I
N
must be selected to match the circuit breaker and back-up fuse.
Dimensioning of the line circuit breaker:
When dimensioning the line circuit breaker also observe the increased environmental temperatures inside
the switch cabinet. Under certain circumstances, this can make a reduction of the charging current specifica-
tion necessary in order to increase the system availability.
● Determine the nominal current according to the type plate specification in coordination with the desired
charging capacity (DIP switch settings for charging current specification) and the power supply line.
Dimensioning of the power supply line:
When dimensioning the power supply line also observe the possible reduction factors and the increased en-
vironmental temperatures in the interior connection area of the charging station (see temperature rating of
the supply terminals). Under certain circumstances, this can lead to an increase of the cable cross-section
and to the adaptation of the temperature resistance of the power supply line.
Mains disconnector:
The charging station does not have its own power switch. The residual current device (RCD) and the line cir-
cuit breaker of the power supply line serve as mains disconnector.
