2. Product description

3. Commissioning

To install the KEBA charging station, please follow the instructions in the "KeContact KC-P30 Charging Station Installation Manual."
Installation Manual — KEBA KeContact KC-P30

You should also read and familiarize yourself with the "Configuration Manual" for the x-series:
Configuration Manual — KEBA KeContact P30 x-series

This quick guide refers to the original user manuals.
It serves as an installation aid for qualified electricians in the area of communication interfaces, but is not a substitute for studying the user manuals.

3.1. Ethernet connection

The network connection is made via the LSA terminal block X4.

Please note that the Ethernet connection X3 (here: RJ45) was designed as a service port. This is not suitable for a permanent, stable connection to the FENECON Energy Management System.

To connect to the LSA terminal block X4, the network cable must be disconnected and the cables need to be connected to pins 1-4.
The assignment type of the customer network must be observed.

Figure 1. Diagram for the network connection

Figure 2. Example of the network connection

There are two ways in which your KEBA KeContact P30 c-series can obtain an IP address. The setup via static IP address or via DHCP is described below.

In a network, IP addresses are typically assigned automatically via DHCP. In many cases, this is handled by the internet router, e. g. a FRITZ!Box. This can cause communication between the FEMS and the charging station to fail. To prevent this, IP addresses can be set to static values.

3.2. Assigning an IP address via DHCP

We recommend setting up via a DHCP server (here: Dynamic Host Configuration Protocol) from the second charging station onwards.

After connection to the customer network, the wallbox is assigned an IP address using DHCP. This IP address can be determined in the DHCP server, e. g. the router, or can be read on the display when the wallbox is started.

Figure 3. Setting the lower switch panel for DHCP

An IP address can only be assigned via DHCP if the DIP switches of the second switch panel D2.1 to D2.4 are set to "OFF".

To be able to access the wallbox via its IP address for testing purposes, your computer must be in the same network. Open an internet browser and enter the IP address identified.

Example: http://123.123.123.123

After entering your login data (included in the scope of delivery), a website opens that looks like this:

Figure 4. KEBA software

The web interface of the KEBA c-series provides access to status information, e. g. the total energy charged. This web interface can only be used for reading, no configurations or settings can be made here.

3.3. Configuration of the DIP switches

Various settings such as IP assignment and control can be made via the DIP switches. In the following illustration you can see the two positions of the switches.

Figure 5. DIP switch

The DIP switches can be accessed by removing the front cover. Here you will find two different switch panels, which we will explain in more detail below.

Figure 6. DIP switch DSW

We differentiate here between the top panel "DSW1" and the bottom panel "DSW2".

3.3.1. Setting the charging station control functions

The first three DIP switches on the upper DSW1 panel are used to control and forward signals from the charging station.

Of these three switches we only need D1.3, which is used to activate the SmartHome interface via UDP, allowing the FEMS to set the charging specifications for the charging station via the UDP protocol. D1.1 and D1.2 remain in the "OFF" position.

Figure 7. Setting the upper switch bar for UDP

3.3.2. Setting the permissible amperage

DIP switches D1.6 - D1.8 are used to set the permissible current, which determines the maximum charging power of the charging station, provided the vehicle to be charged supports this charging power.

Figure 8. Setting the amperage

3.3.3. More DIP switches

However, all other DIP switches have no function in conjunction with the FEMS or can influence the connection, e. g. D2.8.
Therefore they remain in the "OFF" position after commissioning.

Figure 9. Configuring the DIP switches for a wallbox

3.3.4. Charging network

The Keba KeContact P30 c-series can be used as a slave in a charging network with a Keba KeContact P30 x-series. In this case, the x-series takes over the management of the RFID authorization. To enable communication between the charging stations, the DIP switch D2.5 must be activated on all charging stations (x-series and c-series). In addition, the c-series must have received a dynamic IP address from the DHCP server. If there is no charging network (only one charging station is available), the DIP switch D2.5 does not need to be activated.

Figure 10. Setting the DIP switches for a charging network

3.4. § 14a of the Energy Industry Act (EnWG)

From 01/01/2024, all wallboxes & charging stations in the private sector must be controllable by the grid operator in accordance with § 14a of the German Energy Industry Act. Depending on the manufacturer, your wallbox can be dimmed to the required 4.2 kW charging power and/or switched off for the required period of time.

Currently, the proper dimming of wallboxes & charging stations is not achieved via the FENECON energy management, but via solutions provided by the wallbox manufacturers.

Prerequisites

All §-14a-compliant KEBA KeContact Series that can be integrated into the FEMS Online Monitoring are listed below.

Table 1. 14a-compliant KEBA KeContact Series models
Wallbox model type	§-14a compliance (e. g. dry contact X1, Modbus TCP, OCPP)
KEBA KeContact P30 X-Series
KEBA KeContact P30 C-Series
KEBA KeContact P40

A KEBA KeContact can currently be properly integrated into the FENECON Energy Management System via the potential-free contact X1.

Connection of the control box

The device is configured via the potential-free contact X1 of the compatible KeContact charging station.

Connect the control box to the input and output terminals of the potential-free contact X1 as shown in the [Circuit diagram for the potential-free contact X1].

Figure 11. Circuit diagram for the potential-free contact X1

To enable control by external components (here: control box), the DIP switch D1.1 must be set to "ON".

The wallbox then needs to be restarted.

Figure 12. DIP switches for contact X1

Setting up the EnWG-compliant amperage

From software version 1.18 or firmware version 3.10.56, the available charging current for the KeContact P30 series can be set to 0 A or 6 A in accordance with EnWG using the DIP switches.

In software version 1.17.2, the EnWG-compliant current was preset to 8 A. For more information, please refer to the KEBA KeContact manuals or the KEBA KeContact FAQ .

To reduce the charging current to a specific value, set DIP switch D2.6 to the desired position.

Figure 13. Charging current via DIP switch D2.6

Activating DIP switch D1.1 results in new dependencies for starting a charging process using RFID authorization.

Figure 14. Requirements for initiating a charging process

The configuration is now complete.

4. Install FEMS App KEBA KeContact P30 c-series

In the FEMS App Center you will find all installable FEMS Apps — such as the FEMS App KEBA KeContact P30 c-series.

The user manual FEMS App Center provides detailed instructions on how to use the FEMS App Center. It also explains how to register and redeem a license key.

Then follow the instructions in the FEMS App installation wizard on your KEBA KeContact P30 c-series.

4.1. Installation wizard

You will then be taken to the installation wizard for FEMS App KEBA KeContact P30 c-series.

The KEBA KeContact P30 Series is selected as standard.

Some of the input fields are pre-filled. Nevertheless, enter your data if it differs from the default values (e. g. IP address). Otherwise, the default values can be retained (e. g. port, Modbus unit ID).

Mandatory fields are marked with *

Check your entries and make sure that they are correct. Otherwise the respective app will not work properly!

In the next step, you can set a phase rotation.

Please note that phase rotation is only included from FEMS release 2024.11.2 or later.

The phase connection L1_L2_L3 is selected as standard.
