4.3 Tripping Test with Nominal Residual
Current and Measurement of Time to
Trip at Mode 2 Charging Cable
Note!
If you operate your test adapter at an
electrical system with a 30 mA
breaker, the mains RCD may be
tripped during the tripping test (trip-
ping current or time to trip) instead of
the charging cable’s ICCB. In this
case the ICCB-IN1 L1 LED goes out.
We recommend the following procedure in
order to prevent an upstream RCD (selective
RCD as well) from tripping, and to ensure
that actual tripping current or correct time to
trip is measured:
➭ Connect the respective test instrument
with the (L1) pole to the energized pole
of the charging cable L1, N, depending
on the wiring of the earthing contact plug
(ICCB-OUT1), and the (PE) pole to N (ICCB-
IN1) (observe limit values and manufac-
turer‘s details).

➭ Refer to the operating instructions for the
respective test instrument regarding per-
formance of the measurement.
5 Measuring R
C
Testing of specified resistance value RC for
maximum current-carrying capacity of the
mode 2/3 charging cable per
DIN EN 61851-1 (VDE 0122-1)
➭ Connect the
test object as described in
section 3.3.
➭ Measure resistance between the PP and
PE sockets at ICCB-OUT1 with a stan-
dards-compliant measuring instrument.
➭ Compare the measured resistance value
with the value specified in table X (table
B3, DIN EN 61851-1:2012-01).
Note!
Observe the maximum current-carry-
ing capacity specified on the cable.

Measurement (I
PE
) at Mode 2
Charging Cable
➭ Connect the test object as described in
section 3.3.
➭ Switch mains voltage on by turning the
top rotary selector switch (S1) to the
Status C position (system state: vehicle
ready for charging).
➭ Turn the bottom rotary selector switch
(S2) to the first ON position in the orange
area for single-phase interruption.
➭ Close the jaws of the current clamp
transformer around the external protec-
tive conductor loop I
PE
.
➭ Read the measured value for protective
conductor current at the current clamp
transformer.
Protective conductor current should not
exceed 3.5 mA.
