Safe working on the charging system
1.4
Before the charging coupler is plugged into the
vehicle
The charging system's connecting cable must be
•
completely unwound.
Check whether the charging system housing, the
•
connecting cable, the charging coupler and the
connections are undamaged.
Hold the plug connection of the charging system
•
only by the charging coupler, not by the charging
cable.
Make sure that there are no tripping hazards,
•
e.g. due to the charging cable.
During the charging process
Keep unauthorised persons away from the charg-
•
ing system.
Never clean or wash the vehicle using high-pres-
•
sure cleaning equipment while it is connected to
the charging system, because the plug connec-
tion is not resistant to pressurised water.
In case of malfunctions or failure of the charging
system
Disconnect the charging system from the power
•
supply by switching off the respective circuit
breaker in the building's electrical cabinet. Affix
a sign with the name of the person authorised to
switch the circuit breaker back on.
Notify a qualified electrician without delay.
•
Electrical equipment
Keep the charging system housing closed at all
•
times.
1.5 Installation and tests
Information for selecting the protective devices for
basic and fault protection with respect to direct and
indirect contact
Electrical circuit breakers
•
The charging system must be protected with cir-
cuit breakers in compliance with the respective na-
tional regulations. The required protection depends
on factors such as the required switch-off time, in-
ternal network resistance, conductor cross-section,
cable length and the set power of the charging
system. The cable short-circuit protection must
feature a characteristic which permits a current
eight to ten times the value of I
exceed a maximum rated current of 16 A, depend-
ing on the set power of the charging system.
Use exclusively circuit breakers with a rated break-
ing capacity of 6,000 A. The circuit breaker's I²t
value must not exceed 80 kA²s.
Residual current device
•
For reasons of personal safety, connect a dedi-
cated RCD in series with each Wallbox. For this
purpose, use at minimum an RCD type A with
an I
DC residual current detection (IEC 62955-1)
•
The charging system features 6 mA DC residual
current detection. The charging system will
switch off if the residual current reaches or
exceeds 6 mA DC. Please refer to the Diagnostics
chapter for more information.
Information about initial tests after installation
•
and repeat tests
National regulations could require testing the
charging system before start-up and at regular
intervals. Perform these tests in compliance with
the applicable regulations. Instructions on per-
forming these tests are provided below.
PE conductor test
•
Measure the PE conductor continuity after
installation and before switching the device on
for the first time. To do this, connect the charging
coupler to a test adapter for vehicle simulation
according to EN 61851-1. Measure the PE conduc-
tor resistance between the PE conductor socket
of the adapter and the connection point for the
PE conductor in the building's electrical cabinet.
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 insula-
tion measurements. The charging system must
be disconnected 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.

charging system
On the primary side of the charging system,
measure the insulation resistance at the con-
nection point of the charging system's supply
cable in the building's electrical cabinet. The
value must not be less than 1 MΩ.
The Wallbox is equipped with an over-
voltage protection device. This may be
taken into account when performing
the measurement.
