1.5 Installation and tests
Information for selecting protective devices for basic and fault protection against touching directly or indirectly
•
Line protection
The charging system must be protected with circuit breakers in compliance with the respective national
regulations. This depends, for example, on the required tripping time, internal network resistance, conductor
cross-section, conductor lengths, and the preset rating of the charging system. The short-circuit protection
of the conductor must have a characteristic that permits 8-10-fold of the Inom value and must not exceed a
maximum nominal current of 16 A, depending on the preset rating of the charging system.
•
Residual current protective device
For reasons of personal safety, national regulations may stipulate an upstream RCD with an I
AC. Choose a suitable RCD that complies with the national regulations. Heed also the notes from the
section DC residual current detection.
•
DC residual-current detection
The charging system is equipped with 6 mA DC residual-current detection. The charging system switches
itself off if there is a residual current that is greater than or equal to 6 mA DC. Details of this are given in the
Diagnostics section.
•
Information on initial tests after installation and repeat tests
National regulations may stipulate inspections of the charging system before start-up and at regular
intervals. Perform these inspections in accordance with the respective rules and regulations. Information is
given below on how these inspections can be performed.
•
Protective conductor test
After the installation and before switching on for the first time, test the continuity of the PE conductor. For
this, connect the charging coupler to a test adapter for vehicle simulation in accordance with EN 61581-1.
Measure the resistance of the PE conductor between the PE conductor socket of the adapter and the
connection point of the PE conductor in the building's electrical cabinet. The value of the PE conductor for a
total conductor length (connecting line to the charging system and the vehicle charging cable) of up to 5 m
must not exceed 300 mΩ. For longer cables, the value can be increased in accordance with the applicable
national regulations. In any case, the resistance must not exceed a value of 1 Ω.
•
Insulation test
Two insulation measurements are required because the charging system is equipped with a disconnecting
relay. The charging system must be disconnected from the power supply for this. Therefore, before the
measurement, switch off the supply voltage using the circuit breaker in the building's electrical cabinet.
1. Measurement of primary side of charging system.
Measure the insulation resistance on the primary side of the charging system at the connection
point of the power supply line to the charging system in the building'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 secondary side of 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 conductor current. In both cases, the value must not exceed 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 differential current at the connection point of the power supply line to the
charging system in the building's electrical cabinet.
•
Checking of switch-off condition in event of short circuit (Z
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 measurements on the measuring sockets of the test adapter. The values must comply with those of
the selected circuit breaker.

accordance with EN 61581-1. The measurements must be carried out with the adapter in the C mode. Carry
out the measurements on the measuring sockets of the test adapter with a suitable instrument. The values
must comply with those of the selected circuit breaker.
•
Checking the integrated DC residual-current detection
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 measurements on the measuring sockets of the test adapter with a suitable instrument. If the
residual current is greater than 6 mA DC, the charging system must disconnect the charging coupler from
the power supply. The fault indicator on the charging system must be activated.
•
Checking the upstream RCD
The upstream RCD has to be checked at the connection point of the charging system supply in the
building's electrical cabinet. The RCD must trip in accordance with the national regulations.
1.6 Technical data (see Table 1)
1.7 Protective devices (Fig. 1)
The following components are protective devices:
1 Housing, 2 charging cable, 3 protecting cover, 4 charging coupler,
Checking the protective devices
1. Before every charging process, make a visual inspection of the protective devices for damage.
2. Have a qualified electrician make regular electrical function tests in accordance with the national
regulations.
1.8 Controls
The charging system can be operated with a single button/LED combination (Fig. 2/1). An optional external blocking
device (e.g. key switch) can be connected to the internal interface.
LED functions
The LED indicates the operating state of the charging system. Detailed information on the operating states is given
in the operating manual.
Functions of the button
The functions of the button are described in the operating manual.
Starting the charging process
The charging process starts automatically as soon as the charging coupler is plugged in and the vehicle requests a
charging process.
Stopping the charging process
Note
The charging process cannot be stopped with the button. There are 3 ways of stopping the charging process.
•
Stop the charging process with the operating controls in the vehicle. Instructions on this are given in the
vehicle's operating manual.
or
•
Disconnect the charging system from the power supply by switching off the respective circuit breaker in the
building.
or
•
Disable the charging system using the optional external blocking device.
Optional external blocking device
If an external blocking device (e.g. key switch) is connected, the charging process is only started when the Wallbox
has been enabled by the external blocking device.
1.9 Environment
This device is used to charge electric-powered vehicles and it is subject to the corresponding EU Directive
