NOTES ON THIS DOCUMENT

Before installing and using the wallbox the instructions must be read and understood in full by the installer and each user.

Please keep the instructions for the entire service life of the wallbox in order to be able to access them later.

Also observe the operating instructions for your electric vehicle.

SAFETY, INSTALLATION, AND USE

The wallbox is only suitable for use in private and semi-public areas (e.g. company car parks).

The wallbox must not be installed in areas where there is an explosive atmosphere (EX area) or where flammable liquids or

objects are stored.

The wallbox is only suitable for stationary installation. A minimum distance of 50 cm from all neighbouring objects must be

maintained. Installation in a closed box is not permitted. Likewise the wallbox must not be installed in areas at risk of flooding.

The wallbox may only be installed and put into operation for the first time by a trained electrician.

The electrical connection must be made in accordance with nationally applicable standards and other national and international

regulations regarding accident prevention and personal protection as well as fire protection.

The wallbox may only be connected to and operated on TT, TN-C, and TN-C-S networks. Operation on an IT network is not

permitted.

Work on the wallbox may only be carried out when it is de-energised. There is a risk of fatal electric shock due to the

components inside the box!

Modifications or conversions to the wallbox are not permitted and will result in the loss of any guarantee or warranty claims

against the manufacturer.

The box and all associated components may only be used for their intended purpose. The manufacturer accepts no liability for

personal injury or damage to property resulting from improper use.

Defective or damaged wallboxes must not be put into operation. In this case, contact your installer.

Check the function of the RCD switch regularly in accordance with national regulations.

FURTHER INSTRUCTIONS FOR USE

•Vessels containing liquids must not be placed on the charging station.

•Avoid bending or running over the charging cable.

•When the charging station is not in use, the charging cable must be coiled up on the device provided for this purpose

•When not in use, fix the charging hitch in the charging hitch holder provided.

•Before using the charging coupler, check it visually for damage or dirt on the contacts.

•The charging hitch must not be disconnected from the vehicle during the charging process.

•It is forbidden to insert objects into the charging coupler.

•Do not wash the vehicle with a garden hose or high-pressure cleaner when the charging hitch is plugged in, in order

to prevent water from entering the charging hitch or the vehicle's connecting device.

•The vehicle must be parked at a suitable distance from the charging station to ensure that the charging cable can be

plugged in without tension.

•Avoid direct sunlight

•Do not open an outdoor charging station during rain or snowfall.

•The charging cable must not be connected to extension cables or adapter cables.

•Do not allow children to play unsupervised in the vicinity of the charging station.

•The charging station must always be closed during operation.

•The key to open the charging station should be kept in a place where unauthorised persons cannot access it.

•For persons with a pacemaker or defibrillator, no statement can be made about the suitability of use, maintenance or

repair of the charging station, despite compliance with all European directives and standards on electromagnetic

compatibility. Please contact the manufacturer of the defibrillator or pacemaker for further information.

•Improper use may result in serious injury or death, and may destroy the vehicle or the charging station.

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.

The next step is the electrical connection of the wallbox.

ELECTRICAL CONNECTION

The supply line of the wallbox must be disconnected from the power supply during installation work.

CONNECTION TO THE MAINS

The supply line must be correctly fused.

1. Pull the supply cable into the box.

2. Connect the supply cable as shown in figure 2 and then relieve the strain and seal it using the cable gland.

Check the electrical connection and voltages with the help of a meter.

Also make sure that neutral (blue) and earth (PE, yellow/green) are connected correctly.

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 attaching the jumper to the corresponding positionon

the control unit. The slots on this can be found with the label "I max".The

assignment of the slots is shown in the following tables:

VALUES FOR ALPHA NRG1002 (MAX. 22kW PER VEHICLE)

VALUES FOR ALPHA NRG1012 (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 is not to be put into operation.
