During installation, other important issues such as "cascading” of RCD and
selection of a suitable line circuit breaker must be considered.
Dimensioning of the line circuit breaker
When dimensioning the line circuit breaker, the increased ambient tempera-
tures in the control cabinet must also be taken into account! Under certain
circumstances, this can make a reduction of the charging current specifica-
tion necessary in order to increase the system availability.
The nominal current must be determined in accordance with the type plate
data in coordination with the desired charging power (DIP switch settings for
charging current specification) and the supply line.

Dimensioning of the power supply line
When dimensioning the power supply line also observe the possible reduc-
tion factors and the increased environmental temperatures inside the con-
nection 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.
7.3.1
Cable installation
Note the following points during cable installation:
●
The supply line must be sufficiently inserted into the cable gland (sur-
face-mounted cable installation) or the double-membrane seals (flush-
mounted cable installation) so that the cable sheath

is visible in the
connection area.
Correct cable gland (surface-mounted cable
installation)
Double-membrane seals (flush-mounted ca-
ble installation)
●
The double-membrane seals must fit cleanly against the cable sheath-
ing.
