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 EVSE current capac-
ity by setting the DIP-switches in coordination with your installed line circuit breaker (see chapter
“DIP-switch settings”).
The mains supply line must be hardwired to an existing house installation and correspond to the
nationally applicable legal conditions.
Selection of the RCD circuit breaker:
Each charging station must be connected to a separate RCD circuit breaker. No other cir-
cuits may be connected to this RCD circuit breaker.
RCD circuit breaker of at least type A
If the vehicles to be charged are not known (e.g. semi-public area), measures must be met
for protection where direct fault currents (>6mA) occur. This can be realized, for example,
through 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.
The nominal current I
N
must be selected to match the line circuit breaker and the fuse.
Dimensioning the Line circuit breaker:
When dimensioning the line circuit breaker also observe the increased environmental temperatures
in the switching cabinet! Under certain circumstances, this may require a reduction of the pread-
justed charging current setting to increase the system availability.
Maximum value according to the type plate data matching to the DIP-switch settings of the
preadjusted charging current value.
Determine the nominal current in accordance with the specifications on the type plate, in
coordination with the desired charging current (DIP switch settings for the pre-adjusted
maximum EVSE current capacity) and the mains supply line.
Dimensioning of the mains supply line:
When dimensioning the mains supply line also observe possible reduction factors and the in-
creased environmental temperatures in the interior connection area of the charging station (see
„Mains supply terminals temperature rating”)! Under certain circumstances, this can lead to an in-
crease of the cable cross-section and to the adaptation of the temperature resistance of the mains
supply line.
Mains disconnector:
The charging station does not have its own power switch. The RCD circuit breaker and the line
circuit breaker of the mains supply line serve as mains disconnector.
