With the go-e Charger Gemini ex
you have chosen an extremely com-
pact and versatile charging station
for EVs. Smart and intelligent solu-
tions that make charging electric ve-
hicles even more convenient are al-
ready integrated in the go-e Charger
Gemini ex.
The charging unit was developed
with the objective of extreme exi-
bility and, in addition to the advan-
tages of a conventional wallbox, of-
fers you the possibility of charging
anywhere where there is alternating
and three-phase current, provided
that you have the appropriate so-
cket adapter.
The go-e Charger was developed
and tested by electric car drivers for
electric car drivers. To ensure that it
remains up-to-date in the future, we
are constantly developing the rm-
ware and adapting the app to the
state of the art. So let us surprise
you with future functions.

Drivers of electric vehicles are
very consciously opting for this
type of mobility. Electric drives
are quiet and do not emit any
environmentally harmful gases. But
electric vehicles also need energy, which
has to be generated. If we use the availa-
ble energy carefully, we will not need to
expand fossil fuel power plants or nucle-
ar power plants for electric mobility.
An important contribution we can all
make is to use surplus energy. So if pos-
sible, do not charge your car when you
come home after work, as this is the
time when the electricity grid is at its
peak anyway. In order to save energy
and thus also to charge in an environ-
mentally conscious way, you should, if
possible, postpone your charging with
the go-e Charger „Scheduler“ function to
the midday or the early morning hours,
as there is a surplus of electricity in the
grids at this time.
An even more interesting option could
be an electricity supply contract with
our partner aWATTar (currently only
available in Germany and Austria), whe-
re you can benet from the highly uc-
tuating electricity prices at the electricity
price exchange by purchasing electri-
city when it is cheapest. The technolo-
gy for this is already built into each of
our charging boxes. For more informa-
tion, please visit our page at aWATTar:
www.awattar.com/services/goe
We wish you lots of fun with your go-e
Charger and enough electricity at all
times.

4. Safety regulations/notes
Any information regarding electrical in-
stallation is intended exclusively for a
qualied electrician whose training all-
ows all electrical work to be carried out
in accordance with the applicable natio-
nal regulations.
Before carrying out electrical connec-
tion work, you need to de-energise the
circuit.
Installation must be carried out in accor-
dance with local, regional and national
regulations.
Observe the permissible ambient condi-
tions from the data sheet.
A location without direct sunlight is re-
commended.
The Charger is only suitable for charging
gassing vehicle traction batteries in well-
ventilated rooms.
The unit must not be operated indoors
if there is an increased danger from am-
monia gases.
The Charger should not be operated in
the immediate vicinity of ammable or
explosive substances, running water or
heat-emitting equipment.
Electrical protective measures, installation, operation
High voltage - danger to life! Never use
the go-e Charger if the housing is dama-
ged or open.
In case of unusual heat development, do
not touch the go-e Charger, the charging
cable or adapter and stop the charging
process as soon as possible. If the plastic
is discoloured or deformed, contact cus-
tomer support.
Never cover the go-e Charger during
charging. Heat build-up can lead to re.
Persons wearing electronic implants
should keep at least 60 cm away from
the go-e Charger due to electromagnetic
elds.
Due to legal regulations the Gemini ex
Charger must not be used in the follo-
wing countries: Norway.
The go-e Charger Gemini ex has
the communication interfaces WiFi
802.11b/g/n 2.4GHz and RFID. WiFi is
operated on a frequency of 2.4Ghz,
channels 1-13 with the frequency band
2412-2472Mhz. The maximum transmis-
sion power of the WiFi is 20dBm. RFID
is operated on a frequency of 13.56MHz
with a maximum radiated power of
60dBμA/m at 10m.

The go-e Charger Gemini ex 11 kW may
only be operated at the following con-
nections:
CEE red 16 A, 3-phase, 400 V or with
original go-e Charger adapter for Gemi-
ni ex 11 kW at:
•CEE red 32 A, 3-phase, 400 V (limi-
ted by Charger to 16 A, 3-phase)
•CEE blue 16 A, 1-phase, 230 V
•domestic plugs 16 A, 1-phase, 230 V
The go-e Charger Gemini ex 22 kW may
only be operated at the following con-
nections:
CEE red 32 A, 3-phase, 400 V or with
original go-e Charger adapter for Ge-
mini ex 22 kW at:
•CEE red 16 A, 3-phase, 400 V
•CEE blue 16 A, 1-phase, 230 V
•domestic plugs 16 A, 1-phase, 230 V
Always use original go-e adapters. With
the go-e Charger Gemini ex 22 kW,
automatic reduction of the charging cur-
rent to 16 A by plugging in the adapter is
only possible in conjunction with original
go-e adapters.
Observe the maximum permissible char-
ging current of the connection at which
you are charging. If this is unknown,
charge with the lowest charging current.
Fire hazard! We recommend a maximum
charging current of 10 A for use with do-
mestic plugs, as very few domestic so-
ckets/electrical installations are suitable
for continuous operation with 16 A! Na-
tional regulations may prescribe lower
The go-e Charger has to be used hanging
vertically or must be mounted vertically
in the wall bracket on a at wall.
Make sure that the power connection
leading to the go-e Charger is properly
installed and undamaged.
The go-e Charger is equipped with a bu-
ilt-in RCD protection module with direct
current detection (20 mA AC and 6 mA
DC). Therefore, only a type A RCD must
be installed on the building side, unless
local regulations deviate from this. In-
dependently of this, a miniature circuit
breaker must be installed upstream of
each charger.
The go-e Charger may only be operated
at fully functional protective devices.
Connection cables must be suciently
dimensioned.
An electric shock can be fatal. Do not
reach into sockets and plug systems by
hand or with technical aids.
The go-e Charger has a safety function
called „ground check“, which prevents
charging in TT/TN power grids (com-
mon in most European countries) if the
power connection is not grounded. This
function is activated by default. It may
only be deactivated via the go-e Charger
app if you are sure that the power grid
does not have an earth connection (IT
grid, e.g. in many regions of Norway) so
that charging can also take place here.
The go-e Charger visualises a deactiva-
ted „ ground check“ by 4 red LEDs (3, 6,
9, 12 o‘clock).

8. Installation
1. Mount the go-e Charger approx. 1.00 to 1.45
meters above the ground, depending on your
personal feeling of well-being. When determin-
ing the optimum installation position, ensure
that there is a proper distance to the three-pha-
se socket so that the CEE plug of the charging
station can be plugged in easily. The go-e Char-
ger has to be mounted exactly below the CEE
socket so that little pressure is exerted on the
supply line.
Place the wall bracket in the desired mounting
position. Use a spirit level to align it straight.
Mark the four drill holes with a pencil by using
the wall bracket as a template.

8. Installation
5. The go-e Charger is equipped with an integra-
ted RCD protection module with direct current
detection (20 mA AC, 6 mA DC).
Only a type A RCD is required on the building
side, unless local regulations deviate from this.
In addition, a miniature circuit breaker must be
installed upstream.
Miniature circuit breakers with characteristic B
or C for 16 or 32 amperes are permissible:
•3- or 4-pole for three-phase connection
•2-pole for single-phase connection

Ready to charge
The go-e Charger is ready for operation. The
number of blue LEDs corresponds to the set
charging current.
Five predened charging levels can be selected
via the button.
1 LED = 1 A
Gemini ex 11 kW = 6 A - 16 A
Gemini ex 22 kW = 6 A - 32 A
1.
Start of the charger
The go-e Charger performs a self-test during
initial start-up or after a restart, during which
the LEDs light up in rainbow colours.
Plugging in the charger
Connect the go-e Charger Gemini ex directly to
a red CEE socket or to a suitable socket using an
original go-e adap ter.
Gemini ex 11 kW = 16 A
Gemini ex 22 kW = 32 A

1919
Starting the charging process
Connect the go-e Charger and the vehicle by
using a type 2 charging cable (or if the car has
a type one socket by using a type 2 to type 1
adapter cable). Make sure that the type 2 plug is
inserted as far as possible into the type 2 socket
of the charger.
The Charger is ready for charging and is waiting
for the car to release it. The LEDs light up yellow
in the number of the preset charging current.
9. Commissioning/charging
Charging
After the car has enabled charging, the LEDs rot-
ate clockwise around the type 2 socket during
the charging process.
The number of „tails“ corresponds to the num-
ber of connected phases or the number of pha-
ses set in the app:
•1 rotating tail = 1-phase charging (230 V)
•3 rotating tails = 3-phase charging (400 V)
The speed of rotation and length of the tails in-
dicate the amount of charging current.
You can adjust the charging levels individually in
the go-e Charger app („Current levels“). It does
not matter whether the go-e Charger is connec-
ted single-phase or three-phase.
4.

6. Stop charging
The charging process is completed when the
LEDs light up green.
If you want to stop charging prematurely, use
the „cable release“ function of your vehicle or
the large round button of the go-e Charger app
(tab „Charging“).
The cable remains locked in the type 2 socket in
the standard setting after the charging process
has ended (adjustable via the app) until it is re-
moved from the vehicle (theft protection).
If the power supply is interrupted, the char-
ging cable remains locked in the charging box
for reasons of theft protection. To unlock it, it
is necessary to re-energise the charging station.
The cable can also be unlocked automatically
after a power failure, provided the function has
been activated in advance via the „Cable unlock“
setting in the app. However, it is then no longer
theft-protected in the event of a power failure.
The go-e Charger displays the charging status
via dierent colours and positions of the LEDs.
In addition, it executes a whole series of safe-
ty queries to check the used power source for
possible errors. For this reason, the go-e Char-
ger may display an error and refuse to charge,
especially with unknown power sources.
The device visualises the cause of the error by
certain colours and positions of the LEDs. You
can also nd the error message within the „Sta-
tus“ information of the app. (The following co-
lour codes correspond to the factory setting).
