| Configuring the Wallbox eMH3 – Setting up data communication
38
In order to establish a mobile network connection with an OCPP backend, a suitable SIM card must be installed in
the LTE USB stick when commissioning. You can find information about installation in the manual accompanying
the LTE USB stick.
The SIM card is usually included with your backend subscription: in this case, you will also receive the activation
data from your backend operator.
Proceed as follows to set up communication via LTE:
1 Click the Connectivity > Cellular tab and enter
the information provided by your backend operator
for the Access point name (APN), Username
and Password.
y Confirm by clicking the Save button.
2 Switch to the Maintenance > System tab and
click the Hard reset button in the System Restart
section.
y Your Controller/Extender system will now
restart with the selected settings.
A connection can now be established between the Controller charging station and the backend via mobile network
communications.

ABL offers the WiFi dongle E3BWLAN as an optional accessory (see page11) for each Controller Wallbox eMH3:
The installation is described in the section "Connecting the E3BWLAN" on page23. After installation, a connection
can be established between the SBC and a WiFi router and thus to an OCPP backend.
