Onboarding – Configuration of an Extender wallbox for stand-alone operation
An Extender Wallbox eM4 Twin can be configured to operate as a stand-alone charging station. The
Extender as
standalone
operating mode is recommended for:
Private households
Individual parking spaces for companies and/or customers
Applications with a limited user group for which itemised billing is not required
WARNING!
Configuration of the wallbox by a qualified specialist electrical contractor
Before you can start configuring the wallbox, the
ABL Configuration App
displays a safety warning: The inter-
nal parameters of the wallbox may only be changed by qualified specialist electrical contractors.
To continue, you must confirm that are professionally trained and have knowledge of the relevant regulations
of a specialist electrical contractor by tapping the radio button.
Configuring the
Extender as standalone
operating mode within the
ABL Configuration App
is basically self-ex-
planatory or prescribed via the internal structure of the app. Therefore, simply follow the instructions in the app to
adjust the parameters of the Extender wallbox:
Parameter
Description
Network settings
This is where you can connect the wallbox to an infrastructure network (WLAN
or LAN), which you then use to access the wallbox with the app. When operat-
ing without a connection to the infrastructure network, communication is pos-
sible in the vicinity of the wallbox via its internal WLAN interface.
Max. load per charging point
Enter the maximum charging current that can be delivered by the charging sta-
tion here.
Phase-shift detection
You can switch the wallbox’s phase imbalance detection on or off here. If it is
active, you must preset the maximum possible current difference between the
individual phases (16 A or 20 A).
Load shedding
Activate the function that allows external systems (e.g. under TAB 4100) to
temporarily limit or switch off the charging infrastructure. For this function, a
control cable must be connected to terminal
EN1
of the wallbox (see "Connect-
ing a control cable in accordance with VDE AR-N 4100" on page 34).
Access control
Specify whether charging processes need to be authorised via RFID or whether
the wallbox can be used for free charging. If you activate access authorisation
via RFID, you must also configure optionally available RFID media (app, key
fobs, cards) on the wallbox.
QR-Code / Login credentials
To complete the configuration, you can output the access data (WLAN SSID /
password) here as a QR code or write it down to make this information availa-
ble to the owner and/or operator of the wallbox.
To complete the configuration, tap the
Continue
button: The wallbox is now configured and offers the option to ad-
just the parameters just set as well as other operating parameters via the
Continue to Control Board
button.
