ASSEMBLY
PREREQUISITES
The wallbox may only be installed by a trained electrician.
Before installation the device must be thoroughly checked for damage.
The wallbox is only suitable for vertical installation.
The wallbox may be installed indoor or in protected outdoor areas, such as under canopies.
The ambient temperature at the installation site must be in the range of -20°C to +40°C.
The wallbox must be mounted away from easily flammable parts.
Sufficient ventilation must be ensured during operation.
The installation location must be chosen so that the connected charging cables cannot come into contact with water.
To prevent the ingress of water check the proper fit of the cover and the tight fit of the cable glands after installation.
WALL MOUNTING
1. The enclosed mounting plates (left/right) must be mounted on the back of the wallbox using four self-tapping screws
each. Make sure that the bevelled tabs are oriented towards the centre of the housing (see figure 1).
2. Use the enclosed drilling template to transfer the drilling distances for wall mounting to the wall.
3. Drill holes in the wall.
4. Insert four dowels (not included in the scope of delivery) according to the wall condition.
5. Screw the two lower screws into the dowels and place the wallbox on the screws using the screw holes.
6. Screw the upper screws into the wall plugs, align the wallbox and finally fasten it using the four screws.

SETTING THE MAXIMUM CURRENT
It should be noted that the charging speed is essentially dependent on two factors:
1. The maximum power output of the wallbox
2. Maximum charging power of the electric vehicle.
Preferably the wallbox should be connected with three phases.
Before commissioning, the maximum current that the wallbox draws via the supply line must be set using the enclosed jumper
on the control board.
When setting the maximum current, it must not be higher than the fuse or the cable cross-section and the length of the supply
line allow.
The setting is made by plugging the jumper into the corresponding position
on the control unit. The slots on the control unit can be found
by the inscription "I max".
The assignment of the slots is shown in the following tables:
VALUES FOR ALPHA NRG1000 (MAX. 11kW PER VEHICLE)

9
VALUES FOR ALPHA NRG1010 (MAX. 22kW PER VEHICLE)
Check that the jumper is correctly seated before commissioning.
No settings are necessary to divide the charging current between two vehicles. The charging current is regulated by the control
unit.
Due to the increased cable length of the supply line, it may also be necessary to compensate for the resulting voltage drop by
using a larger cable cross-section.
INITIAL COMMISSIONING
1. Before commissioning the wallbox, disconnect all vehicles from the system.
2. Switch on the fuse in your house power box.
3. Switch on the RCD switch located in the box.
The microcontroller will now start automatically. Within 2 seconds, the box reports the preselected settings by flashing
all LEDs. The number of flashes indicates the presetting. For example, if the LEDs flash ten times, the presetting is 10A.
After successful commissioning the red LED on the control board goes out. The green LED, on the other hand, lights up
permanently.
4. The door must be locked with the enclosed triangular key.
If the red LED remains permanently lit, there is a fault in the system.
In this case, the wallbox must not be put into operation

OPERATION
This charging station is suitable for electrically charging one or two vehicles with type 2 charging couplings.
Please also refer to the operating instructions for your electric vehicle.
LED-DISPLAY
The wallbox is equipped with a separate LED indicator light for each charging cable, which shows the current status during
operation.
LED-DISPLAY DEVICE STATUS
Green No vehicle connected, wallbox ready for operation
Blue No vehicle connected, box locked via RFID module*.
Yellow Vehicle connected, waiting state, charging process completed
Green, flashing slowly Vehicle is being charged
Red, flashing repeatedly 3 times Fault on cable, charging coupler or vehicle
Red, flashing quickly Short circuit on cable, charging coupler or vehicle
3 seconds pink flashing RFID card* not known / all RFID cards* successfully deleted
3 seconds white RFID card* has been tuned in
*Depending on the version of the box, an RFID module is available. The RFID module can be retrofitted as an accessory.
The LED indicator lights also show the preset current consumption every time the box is restarted.
CHARGING
Connect your vehicle to the wallbox.
As soon as the electric vehicle is ready for charging the charging process starts automatically.
After successful charging, the vehicle ends the charging process automatically. “Overcharging" is therefore not possible.
If two vehicles are charged at the same time the wallbox regulates the available power. For example, the charging current is
divided between the two vehicles. If the charging process of one of the two vehicles is completed, the charging power of the
vehicle still charging is automatically increased.

11
SEQUENTIAL CHARGING
Note: The time-delayed allocation of the charging current is not supported by all electric vehicles.
A charging current of at least 6A is required for each vehicle to be charged.
If the wallbox has been configured for a low charging current, this may mean that not both vehicles can be charged at the same
time. In this case, the two connected vehicles are charged one after the other (sequentially).
If the charging process of the second vehicle does not start automatically, it may be necessary to disconnect the vehicle from the
system for a short time first. After reconnection, the charging process starts.
As a precaution, observe the connection sequence to the box. First connect the vehicle that does not support sequential charging.
Only then connect the second vehicle (sequential charging is supported by this one).
RESTARTING THE BOX
To restart the box, first disconnect all vehicles from the system.
Switch off the wallbox's internal RCD for 5 seconds.
After switching on the voltage, the microcontroller of the box restarts automatically.
Within 2 seconds, the box signals the preselected setting by white flashing of the LEDs, e.g. 10 flashes signal a presetting of 10
amps.
MAINTENANCE AND CLEANING
In the event of a defect, please contact the manufacturer directly.
For safety reasons, the wallbox must be disconnected from the mains before cleaning.
Dirt can be removed with a damp cloth.
The use of harsh cleaning agents is not permitted.
The wallbox must not be cleaned with a water jet or high-pressure cleaner.
ENVIRONMENT
Dispose of the packaging material via the collection containers for paper and plastics provided for your region.
The disposal of old appliances and their accessories is carried out in accordance with the national and regional regulations for the
disposal of electrical and electronic appliances. Accordingly, these must not be disposed of with household or bulky waste.
