Option 2: 230 V 1-phase with neutral
For 1-phase use of a Wye-connected secondary, only a
single phase (L1 or L2 or L3) and neutral on the grid must
be connected to the L1 and N on the charging station.
This phase voltage must measure 230 V between line and
neutral.
CAUTION:
Only a BusinessLine with a 1P+N RCBO or a
BusinessLine without an RCBO must be connected
to a single phase grid. A BusinessLine with a 3P+N
RCBO must not be connected to a single phase
grid.
Option 3: 230 V 1-phase without neutral
In this configuration (without neutral and 230 V from line to
line), connect any two lines (L1, L2 or L3) of the grid to L1
and N on the charging station.
WARNING:
In this configuration, the charging station operates
only from a single phase (L1). Do not connect the
remaining phases L2 and L3.
CAUTION:
Only a BusinessLine with a 1P+N RCBO or a
BusinessLine without an RCBO must be connected
to a single phase grid. A BusinessLine with a 3P+N
RCBO must not be connected to a single phase
grid.
4.1.5. Route power supply cables
Use minimum 2.5 mm
2
and maximum 16 mm
2
copper wire, depending on the power rating and
distance between the meter cabinet and the charging station. The voltage drop must not exceed 5% (it
is advisable to have a maximum allowable voltage drop of 3%).
For a charging station with a RCBO: When you calculate the length and the diameters of the power
cables, make allowance for the rated short circuit current capacity of the RCBO inside the station.
• For the 3-phase 32A RCBO, the short circuit current is 4.5 kA.
• For the 3-phase 16A RCBO and the 1-phase 32A RCBO, the short circuit current is 6 kA.
A double socket charging station with a product number 'Bxxx2-Ex801' has two separate power cable
inputs. A double socket charging station with a product number 'Bxxx2-Ex901' has a single power
cable input. Refer to the product type guide for more information.
Route the power supply cables to the position where the charging station will be installed. Make sure
of the following:
• There must be enough cable for it to extend at least 500 mm out of an installed Combipole or Wall
Spacer.
• There must be enough cable for it to move and bend safely during installation of a Combipole.
