Installation Manual
power supply line to the charging system in the build-
ing‘s electrical cabinet. The value must not exceed 1
MΩ.
Note: The Wallbox has a surge protector. This may be
considered in the course of making measurements.
2. Measurement of the secondary side of the charging
system.
For this, connect the charging coupler to a test adapter
for vehicle simulation in accordance with EN 61581-1.
Measure the insulation via the measuring sockets on
the test adapter. The value must not exceed 1 MΩ.
Alternatively, the differential current method can be
used in conjunction with measurement of the PE con-
ductor current. In both cases, the value must not ex-
ceed 3.5 mA.
For these measurements, connect the charging coupler
to a test adapter for vehicle simulation in accordance
with EN 61581-1. The measurements must be carried
out with the adapter in the C mode. Measure the dif-
ferential current at the connection point of the pow-
er supply line to the charging system in the building‘s
electrical cabinet.
• Test of the power-off condition in case of a short-
circuit (ZL-N)
For these measurements, connect the charging coupler
to a test adapter for vehicle simulation in accordance
with EN 61581-1. The measurements must be carried
out with the adapter in the C mode. Carry out the mea-
surements on the measuring sockets of the test adap-
ter. The values must comply with those of the selected
circuit breaker.
• Test of the power-off condition in case of a fault
(ZL-PE)
For these measurements, connect the charging coupler
to a test adapter for vehicle simulation in accordance
with EN 61581-1. The measurements must be carried
out with the adapter in the C mode. Carry out the mea-
surements on the measuring sockets of the test adap-
ter with a suitable instrument. The values must comply
with those of the selected circuit breaker.
• Test of the integrated DC residual-current detec-
tion
For these measurements, connect the charging coupler
to a test adapter for vehicle simulation in accordance
with EN 61581-1. The measurements must be carried
out with the adapter in the C mode. Carry out the mea-
surements on the measuring sockets of the test adap-
ter with a suitable instrument. If the residual
current is greater than 6 mA DC, the charging system
must disconnect the charging coupler from the pow-
er supply. The fault indicator on the charging system
must be activated.
• Test of the integrated AC residual-current detec-
tion
For these measurements, connect the charging coupler
to a test adapter for vehicle simulation in accordance
with EN 61581-1. The measurements must be carried
out with the adapter in the C mode. Carry out the mea-
surements on the measuring sockets of the test adap-
ter with a suitable instrument. If the residual current is
greater than 30 mA AC, the charging system must dis-
connect the charging coupler from the power supply.
The tripping time must be less than 40 ms. The fault
indicator on the charging system must be activated. If
the upstream RCDs are correctly dimensioned, this is
does not trip.
• Test of the upstream RCD
Due to the integrated AC residual-current detection,
the upstream RCD must be tested at the connection
point of the power supply line to the charging system
in the building‘s electrical cabinet. The RCD must trip in
accordance with the national regulations.
