The initial steps for commissioning are professional installation and the electrical connection of the wall box.
For more information in the installation instructions:

>> The installation instructions can be found here <<

Icon Exclamation Mark LoxoneThe installation and commissioning of the wall box must be carried out only by a trained and authorised electrician.
The laws, standards and installation regulations of the respective country must be adhered to!


After the wall box has been installed, the Ethernet cable can then be connected. The DIP switches must be set correctly on the board.

Keba Wallbox Dip Switches

The upper DIP switch (DSW1) are used for general configuration of the wall box, for example, to set the maximum charge current.

With the lower DIP switches (DSW2) are for how the network is configured.

In the adjacent image, this is to show the switch positions; on / off.

DSW1 positions

For communication between wall box and mini server can be established, the UDP interface must be activated at the wall box.

Set to the DIP switches to a DSW1.3.

Use the dip switches to DSW1.6 DSW1.8 the maximum charging current can be set.

In the second row, among other things, the network configuration is made.
Thus, the wall box is assigned an IP address automatically, the DIP switches must be turned off to DSW2.1 DSW2.6.

The further adjustment of the DIP switches, as well as information about the startup mode of the wall box are the instruction manual to remove.

Icon Exclamation Mark LoxoneIf the DHCP server is unreachable during a restart of the wall box it will not get an IP address assigned and is thus disconnected from the network.
In such cases start the Wallbox again with an accessible DHCP server. The wall box will now obtain a valid IP address.


After the wall box connected to the network and the power supply has been activated, it will be inserted with Loxone Config in the programming.

Start initially to the Loxone Config Software and connect to your Mini Server. Now load the current program from the mini server, and then click the button “Network Device Search”.

Network Device Search

This will open the search dialog box. In “Network” tab, all network-compatible devices are now listed. Now Mark the wall box and then click the green “+” to insert the wall box in the programming.

The wall box is now listed in the periphery tree.

Further programming is done with the config block “Wallbox”.
