Foratotalcablelength(connectingcableofthe
chargingsystemandvehiclechargingcable)ofup
to5m,thePEconductorresistancemustnotexceed
300mΩ.Ifthecablesarelonger,allowancesmust
be added in accordance with the applicable national
regulations. In any case, the resistance must never
exceed1Ω.
• Insulation test
The charging system is equipped with a discon-
necting relay and therefore requires two insulation
measurements. The charging system must be discon-
nected from the mains for this purpose. Therefore,
switch off the mains voltage at the circuit breaker in
the building’s electrical cabinet before performing
the measurement.
» First measurement on the primary side of the
charging system
On the primary side of the charging system, meas-
ure the insulation resistance at the connection
point of the charging system’s supply cable in the
building’s electrical cabinet. The value must not be
lessthan1MΩ.
The charging system is equipped with an
overvoltage protection device. This may be
taken into account when performing the
measurement.
» Second measurement on the secondary side of
thecharging system
To do this, connect the charging coupler to a
test adapter for vehicle simulation according
toENIEC61851-1.Performtheinsulationmeas-
urement via the measuring sockets on the test
adapter.Thevaluemustnotbelessthan1MΩ.
Alternatively,thedifferential-currentmethodin
combination with measuring the PE conductor
currentcanbeused.Avalueof3.5mAmustnot
beexceededineithercase.Toperformthese
measurements, connect the charging coupler
toatestadapterforvehiclesimulationaccording
toENIEC61851-1.Themeasurementsmustbeper-
formedinadapterstateC.Thedifferential-current
measurement must be performed at the connec-
tion point of the charging system’s supply cable in
the building’s electrical cabinet.
Depending on the measuring instrument
used, it might not be possible to perform
thefollowing measurement on the adapter.
In this case, perform the test at the connec-
tion terminals.
• Testing the switch‑off condition in the event of
ashort circuit (Z
L-N
)
To perform these measurements, connect the charg-
ing coupler to a test adapter for vehicle simulation
accordingtoENIEC61851-1.Themeasurementsmust
beperformedinadapterstateC.Performthemeas-
urements at the test adapter’s measuring sockets.
The values in accordance with the selected circuit
breaker must be observed.
• Testing the switch‑off condition in the event of the
RCD tripping
To perform these measurements, connect the charg-
ing coupler to a test adapter for vehicle simulation
accordingtoENIEC61851-1.Themeasurementmust
beperformedinadapterstateC.Performthemeas-
urement at the measuring sockets of the test adapter
using a suitable measuring instrument. The values in
accordancewiththeselectedRCDandthenetwork
must be observed.
• Testing the integrated DC residual current detection
To perform these measurements, connect the charg-
ing coupler to a test adapter for vehicle simulation
accordingtoENIEC61851-1.Themeasurementsmust
beperformedinadapterstateC.Performthemeas-
urements at the test adapter’s measuring sockets
using a suitable measuring instrument. The charging
system must disconnect the charging coupler
fromthemainswhentheresidualcurrentexceeds
6mADC.Thefaultdisplayonthechargingsystem
must respond.
• Testing the upstream RCD
TheupstreamRCDmustbetestedattheconnection
point of the charging system’s supply cable in the
building’selectricalcabinet.TheRCDmusttripin
accordance with the national regulations.
1.6 Information about signs, symbols and
labelling
Hazard warning:
Information about a possibly hazardous situation that
couldbefatalorresultinsevereinjuriesifthesafety
measuresarenotobserved.Allworktobeconductedby
skilled personnel only.
Note:
supplementary information.
1.7 Protective devices
The following components (Fig.11) are protective
devices:
No.1housing,no.5couplerholder,no.6chargingcou-
pler,no.7chargingcable
Checking the protective devices
» 1.Visuallyinspecttheprotectivedevicesfordamage
before every charging process.
» 2.Haveaqualiedelectricianperformtheelectrical
function tests at regular intervals in compliance
with the national regulations.
