SPECIFICATIONS

General criteria for selecting an installation site

The Wallbox has been designed for indoor and outdoor use. It is therefore necessary to ensure the
correct installation conditions and protection for the device at the installation site.

Take into account the local electrical installation regulations, fire prevention regulations and
accident prevention regulations as well as the rescue routes at the site.

Do not install the Wallbox at locations:

Which are used as escape and rescue routes.
Which are inside potentially explosive zones (EX environment).
At which the Wallbox is exposed to ammonia or ammonia gases (for example in or near
stables).
At which the Wallbox may be damaged by falling objects (for example suspended ladders or
car tyres).
At which the Wallbox is on a direct personnel route and people could stumble over the
connected charging cable.
At which the Wallbox may be struck by jets of water (for example due to neighbouring manual
car wash systems, pressure washers or garden hoses).
At which the installation surface does not have sufficient strength to withstand the mechanical

stresses.
If possible install the Wallbox so that it is protected from direct rainfall so as to avoid the effects of
weather, icing, damage by hailstones or the like.

If possible install the Wallbox so that it is protected from direct sunlight to prevent the charging
current being reduced or the charging process being interrupted as a result of excessive
temperatures on components of the Wallbox.

Comply with the permitted ambient conditions, see section Technical data.
Ensure compliance with national and international installation standards and regulations, for

example IEC 60364-1 and IEC 60364-5-52.
Ensure compliance with national regulations (for example the charging column regulation

in Germany) for the implementation of the EU Directive (2014/94/EU) relating to the
binding minimum technical specifications for sockets and vehicle couplings for charging
electric or plug-in hybrid vehicles in areas accessible to the public. This regulation relates to
charging points on public land as well as department store or customer car parks, for example.
Charging points on private carports or private garage entrances are not generally publicly
accessible charging points in terms of this regulation.

Note

If the device is installed in a location where it is not protected from the weather, for example in
an outdoor car park, the charging current will be reduced to 16 A if the temperature exceeds
the limit value.

14

Specifications for the electrical connection

When it is delivered, the Wallbox is set to 10 A.

Make sure that you set the maximum current to suit the installed circuit breaker using the DIP
switches, see section DIP switch settings.

Selecting the residual-current-operated circuit breaker

The supply cable must be permanently wired into the existing building installation and comply with the
national statutory regulations.

Each Wallbox must be connected using a separate residual-current-operated circuit breaker. No
other circuits may be connected to this residual-current-operated circuit breaker.

RCCB at least Type A (30 mA trip current).
Additional action has been taken in the device to provide protection in the event of DC fault current
(>6 mA DC). In addition, the specifications of the vehicle manufacturer must be observed.

The rated current IN must be selected to suit the circuit breaker and the back-up fuse.

Selecting the circuit breaker

When selecting the circuit breaker, also take the increased ambient temperatures in the control cabinet
into consideration. In certain circumstances this may require a reduction in the charging current to
increase the system availability.

Set the rated current to suit the model plate details in conjunction with the required charge rating (DIP
switch settings for the charging current) and the supply cable.

Selecting the supply cable

When selecting the supply cable, take into account the possible reduction factors and the increased
ambient temperatures in the internal connection area of the Wallbox, see the temperature rating of the
supply terminals. In certain circumstances this may require an increase in the cable cross-section and
an adjustment in the temperature resistance of the supply cable.

Mains isolation device

The Wallbox does not have its own mains switch. The residual-current-operated circuit breaker and/or
the circuit breaker in the supply cable are used as a mains isolation device.

EN

15

INTEGRATION OF EXTERNAL METERS

1 Public mains supply 4 Post-meter fuse
2 Pre-meter fuse (reinforced fuse, SLS switch,

etc.)

3 Mains operator's electricity meter 6 Meter 2 (optional, photovoltaic meter)

Note

This sample circuit diagram provides a system overview and does not contain all the additional
equipment required for operating the system safely (circuit breakers, RCCB, etc.). The PV
power supply may also take a different form.

5 Domestic connection meter

Domestic connection monitoring (post-meter fuse)

The domestic connection monitoring function charges the car dynamically at any time using the
available charging current depending on the other consumers on the domestic connection. This
ensures that the domestic connection fuse is not overloaded and a lower charging capacity than
possible for the car and the installation does not generally have to be selected.

16

The Wallbox receives all its current power from the power supply through meter 5. This information
in combination with the value for the post-meter fuse 4 defined using the DIP switches enables the
Wallbox to control the charging current such that the maximum power consumption never exceeds the
post-meter fuse value.

Installation of external meters

The meter can be connected to the Wallbox Plus via RS485 (Modbus).

The installed meters must be connected with the same phase sequence as the Wallbox so that the
domestic load calculation can be performed correctly. If the Wallbox has to be connected starting with
phase 2 to ensure better division of the phase loads, the meters must also be connected starting with
phase 2.

Note

Detailed information on the meter installation is available in the installation instructions provided
by the meter manufacturer.

Note

The meter values may undergo a plausibility check after connection using the Wallbox web
interface. Information on the Wallbox web interface is provided in the operating manual for the
MINI Wallbox in the section headed "Configuration".

Meters with Modbus RTU (RS485) interface

Using this interface it is possible to operate multiple meters from different manufacturers on a single
bus. A separate cable is required from the Wallbox to the domestic installation for connection. The
advantage compared to network-capable Modbus TCP meters is the fact that it is not dependent
on additional infrastructure such as routers. This ensures high operational reliability if the cabling is
correct.

A detailed description of the connection of Modbus RTU meters via RS485 is provided in the section

RS485 connection X2.

Note

The permitted fuse value must be set using the DIP switches in the connection area of the
Wallbox, see section DIP switch settings.

The current list of supported meters can be found on the BMW Service page for charging products at

https://charging.bmwgroup.com/web/wbdoc/.

EN

17

DIP switch settings

The use of the domestic connection monitoring
function with RS485 meters must be selected
using a DIP switch setting and does not come
into effect until the Wallbox has been restarted.
If no meter 5 is found when the ModBus function
has been enabled, the charging current is
reduced to 10 A.

No monitoring: DSW1.2 = OFF (default)
Monitoring function: DSW1.2 = ON

This reduction is also visualised on the Wallbox
status LED. Further information is provided in the
Wallbox operating manual.

18

INSTALLATION

Note

The maximum charging current of the Wallbox on delivery is set to 10 A.

Installation requirements

Follow the local installation regulations.
The electrical connection (supply cable) must be prepared.
Acclimatisation: If there is a temperature difference of more than 15 °C between transport and the

installation site, the Wallbox must be acclimatised unopened for at least two hours.
Opening the Wallbox immediately may result in condensation formation in the interior and

cause damage when the device is switched on. In certain circumstances, damage caused by
condensation formation may also not appear until a later date after the installation.
Ideally, the Wallbox should be stored for a few hours in advance at the installation site. If this is not
possible, the Wallbox should not be stored in low temperatures (< 5 °C) overnight outdoors or in a

IP address (MINI Wallbox Plus)

REFER TO IP ADDRESS VIA DHCP (NO ADDRESS)
DSW2.1 to DSW2.4=OFF / DSW2.6=OFF

The Wallbox attempts to obtain an IP address
through a DHCP server. This is also the
default setting for a Wallbox without a network
connection.

USE A FIXED IP ADDRESS
DSW2.1 to DSW2.4 / DSW2.6=ON

The addressing process is completed using DIP
switches DSW2.1 to DSW2.4. The configurable
Ethernet addresses start at 10 + DIP switch
setting.
Addresses 11 to 25 can be used
[192.168.25.xx] with 4-bit addressing. Subnet
mask: [255.255.255.0]
DSW2.1 = address bit 20 (Value=1)
DSW2.2 = address bit 21 (Value=2)
DSW2.3 = address bit 22 (Value=4)
DSW2.4 = address bit 23 (Value=8)

Example for address "17":
DSW2.1 = ON (Value=1)
DSW2.2 = ON (Value=2)
DSW2.3 = ON (Value=4)
DSW2.4 = OFF (Value=0)
Address= 10 + 1 + 2 + 4 + 0 = 17

COMMISSIONING

General commissioning procedure

Clean the connection area (remove material residues and dirt).
Before commissioning, check that all screw and clamp connections are tight!
Check that all unused cable glands are properly sealed with dummy plugs or dummy connections.
Switch on the supply voltage. After start-up and after the self-test, the RFID status display is white.
Complete the specified initial tests in compliance with local regulations and laws.
Close the Wallbox terminal panel cover if it has been opened, see section Installing the termination

panel cover.

Install the housing cover, see section Install the housing cover.

Commissioning mode/Self-test

The Wallbox can be switched to commissioning mode to support the initial system test. A device self­test is carried out (lock, contactor control, current measurement, etc.) and an error is displayed.

After a successful test without the vehicle connected, the contactor is switched for a limited time (~10
minutes) to enable the initial tests. Normal charging is not possible in commissioning mode.

The lock on the charging socket is activated to prevent a connection (Wallbox versions with a charging
socket only).

For safety reasons, switching on the Wallbox in commissioning mode via the supply voltage leads to an
error (white-red-red-red) in order to prevent unattended activation.

Activating commissioning mode

1. Set the DIP switch DSW2.8 to ON.

2. Reset the Wallbox. To do this, press the Service button for 1second (signal tone).
Commissioning mode is now enabled and is indicated by the status LED being lit in orange.

3. It is now possible for approximately 10 minutes to contact with the measuring instrument using
standard test clips (for example Astaco® test clips from BEHA) and conduct the required safety
tests. After this time the contactor is disabled and the Wallbox switched off.

Deactivating commissioning mode

1. Set the DIP switch DSW2.8 back to OFF.

2. Reset the Wallbox. To do this, press the Service button for 1 second (signal tone) or switch the
supply voltage off and on again. The Wallbox starts up in normal operating mode and is ready for
operation.

Safety tests

Before using the device for the first time, check the effectiveness of the system's protective
measure(s) according to national regulations such as ÖVE/ÖNORM E8001-6-61, DIN VDE 0100-600.

Check that the effectiveness of the safety feature(s) of the system complies with national regulations
before commissioning the device.

Electrical systems or devices must be tested by the installer of the system or device before being used
for the first time. This also applies to the extension or modification of existing systems or electrical
devices. However, it must be clearly repeated at this point that compliance with all regulations for the
protection measures is mandatory.

Among others, the following points must be given due consideration:

1. The tests: Continuity of the protective conductor connections, insulation resistance, residual­current-operated circuit-breaker tripping current and trip time must be conducted for the extended
or modified part.

2. The measuring instruments used must comply with national regulations, for example
DIN EN 60557 (VDE 0413) "Electrical safety in low voltage networks up to AC 1000 V and
DC 1500 V".

3. The meters used must comply with national regulations.

4. The measurements must be documented. A test log must be prepared for the test and archived.

RFID authorisation

The supplied RFID cards are pre-programmed at the factory for all Wallboxes, which means that the
function of the Wallbox Plus is active.

To disable the RFID function or program additional cards, please refer to the programming instructions
in the operating manual.
