2 SAFETY
2.1 Safety instructions
Improper use and non-compliance with the operating
manual may jeopardize:
• your life
• your health
• charging system and vehicle.
Safety devices on the charging system
• must not be removed,
• must not be manipulated,
• must not be bypassed,
• before each use, it must be checked that the equip-
ment (e.g. housing, connecting line, charging coupler)
is undamaged,
• must be repaired or replaced as necessary, in order
to preserve the functional properties.
Ensure that:
• safety identifications, e.g. yellow-colored marks,
• danger signs and
• safety lights
remain easily visible and retain their effectiveness.
• When operating the charging system, do not use
any extension cables, cable reels, multisocket power
strips, or travel adapters.
• Do not insert any objects into the charging coupler of

• Do not disconnect the charging coupler from th ve-
hicle during charging.
wallbe® takes responsibility only of the charging sys-
tem in its delivered condition and for any work perfor-
med by skilled wallbe® personnel.
Notes for people with a pacemaker (PM) or implanta-
ble cardioverter defibrillator (ICD)
Charging systems from wallbe® that are operated as
intended, comply with the European guideline on elec-
tromagnetic compatibility regarding radiated interfe-
rence.
Should people with a pacemaker (PM) or implantable
cardioverter defibrillator (ICD) wish to conduct activities
on charging systems and their devices in the inten-
ded manner, wallbe® is not in a position to make any
statement regarding the suitability of such medial de-
vices. wallbe® is not able to assess the pacemakers or
concerned implantable cardioverter defibrillators with
regard to their susceptibility to electromagnetic radia-
tion. This is something that only the manufacturers of
the pacemaker or implantable cardioverter defibrillator
can do.
wallbe® therefore recommends only allowing the peo-
ple in question to work on its charging systems after
consultation with the manufacturer of the pacemaker/
defibrillator and the relevant insurance company. En-
sure at all times that no health or safety risks are in-
volved.
Note: People with a pacemaker or defibrillator may not
work on or stand near the charging systems and their
devices, e.g. to perform maintenance operations or
rectify any faults.
Working on the charging system without risk
Before plugging the charging coupler into the vehicle
• The connecting line of the charging system must be
completely unwound.
• Check whether the housing of the charging system,
the connecting line, the charging coupler, and the
connectors are undamaged.
• Take hold of the plug-in connection of the charging
system only on the charging coupler and not on the
charging cable.
• Ensure that no-one can trip e.g. over the charging
cable.
During the charging process
• Keep unauthorized persons away from the charging
system.
• When the charging system is connected, you must

Driving eMobility 5/16
Installation Manual
not clean or wash the vehicle with a high pressure
cleaner because the plug-in connection is not sealed
against pressurized water.
In case of malfunctions or failure of the charging sys-
tem
• Disconnect the charging system from the power
supply by switching off the respective circuit brea-
ker in the building. Leave a sign with the name of the
person authorized to switch on the circuit breaker.
• Call in a qualified electrician immediately.
Electrical devices
• The housing of the charging system must always be
kept closed.
2.2 Installation and tests
Information for selecting protective devices for basic
and fault protection against touching directly or indi-
rectly
• Electrical circuit breakers
The charging system must be protected with circuit
breakers in compliance with the respective national re-
gulations. 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 circuit breaker
For reasons of personal safety, national regulations
may stipulate an upstream RCD with an IΔN of 30 mA
AC. Choose a suitable RCD that complies with the nati-
onal regulations. For this, please refer to the comments
in the sections DC and AC residual-current detection.
• DC residual-current detection
The charging system is equipped with 6 mA DC resi-
dual-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.
•
• AC residual-current detection
The charging system is equipped with integrated AC
residual-current detection as a convenience function.
This residual-current detection switches off the char-
ging system, at the latest, if there is a residual current
greater than 30 mA AC. Details of this are given in the
Diagnostics section.
Notwithstanding this convenience function, a shortac-
ting RCD must be connected upstream of the charging
system, if necessary. The AC residual-current detection
is not a substitute for an RCD.
Information on initial inspections after installation and
repeat inspections
National regulations may stipulate inspections of the
charging system before start-up and at regular inter-
vals. Perform these inspections in accordance with the
respective rules and regulations. Information is given
below on how these inspections can be performed.
• PE 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 con-
nection point of the PE conductor in the building‘s elec-
trical cabinet. The value of the PE conductor for a total
conductor length (connecting line to the charging sys-
tem 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 ex-
ceed 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 mea-
surement, switch off the supply voltage using the cir-
cuit breaker in the building‘s electrical cabinet.
1. Measurement of the primary side of the charging
system.
Measure the insulation resistance on the primary side
of the charging system at the connection point of the

Driving eMobility 6/16
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.
