Thank you for your purchase decision
Warning of a hazardous situa-
tion that may result in damage
to health, fatal injuries or da-
mage to property if the safety
regulations are not followed.
The activity may only be car-
ried out by a qualied electri-
cian.
Hint for a more ecological or
economical use of the product.
Note regarding the adaptation
of the product or product func-
tions to individual needs.
1. Important symbols
2. Sustainable charging
With the go-e Charger Gemini you have
chosen an extremely compact and ver-
satile charging station for electric vehic-
les. Smart and intelligent solutions that
make charging electric cars even more
convenient are already integrated in the
go-e Charger Gemini.
Compared to the classic wall charging
station, the go-e Charger Gemini can be
installed more quickly by an electrician
and easily connected to an existing junc-
tion box where applicable.
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 rmware 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
The go-e Charger may only be used for
charging battery electric vehicles (BEV)
and plug-in hybrids (PHEV) with the ad-
apters and cables intended for this pur-
pose.
Disregarding the safety regulations can
have serious consequences. go-e GmbH
declines any liability for damage caused
by disregarding the operating instruc-
tions, safety regulations or warnings on
the unit.
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 or the char-
ging cable and stop the charging process
as soon as possible. If the plastic is disco-
loured or deformed, contact customer
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 go-e Char-
ger Gemini must not be used in the
following countries: Sweden, Denmark,
Netherlands, France, Italy and United
Kingdom.
The go-e Charger Gemini has the com-
munication 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 transmission 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.
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.

Connection, plug
Do not use go-e Charger if any cable at-
tached to or plugged into the unit is da-
maged.
Never use wet or dirty plugs in connec-
tion with the go-e Charger.
Never pull plugs out of the connector by
the cable!
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.
The go-e Charger must be mounted ver-
tically 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).

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
6. The go-e Charger Gemini may be connected sin-
gle-phase and three-phase. If necessary, lay an
additional supply line. When selecting the cable
cross-section, observe the simultaneity factor
and the type of installation. We recommend the
following cable cross-sections, but the electri-
cian has to decide according to local conditions:
Gemini 11 kW Gemini 22 kW
as surface-
mounted at least 2.5 mm² at least 6 mm²
in wall at least 4 mm² at least 6-10
mm²
in insulation at least 10 mm² at least 10 mm²
The connection cable of the go-e Charger Ge-
mini may also be shortened. Connection via a
junction box is possible.

3. 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.
2. 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.
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.
1 LED = 1 A
Gemin 11 kW = 6 A - 16 A
Gemini 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.

2020
9. Commissioning/charging
5. 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.
4. 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.
