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

The "Configuration Manual" for the x-series should also be read and internalized:
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

Establish the network connection 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 Heckert Solar 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

After connection to the customer network, the wallbox is assigned an IP address using DHCP. This IP address must be determined in the DHCP server, e. g. the router.

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".

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 Keba c-series web interface provides access to status information such as the total energy charged. This web interface can only be used for reading, no configurations or settings can be made here.

3.2. 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".

3.2.1. 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 EMS 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

3.2.2. 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

3.2.3. More DIP switches

However, all other DIP switches have no function in conjunction with the EMS 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

3.2.4. 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

3.3. § 14a of the German 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 Heckert Solar energy management, but via solutions provided by the wallbox manufacturers.

Prerequisites

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

Table 2. 14a-compliant KEBA KeContact Series models
Wallbox model type	§-14a conformity (e. g. potential-free contact X1, Modbus TCP, OCPP)
KEBA KeContact P30 X-Series
KEBA KeContact P30 C-Series
KEBA KeContact company car wallbox
KEBA KeContact PV Edition

A KEBA KeContact can currently be properly integrated into the Energiemanagement 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 predefined to 8 A. For further information, please refer to the KEBA KeContact manuals or visit 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

Die Konfiguration ist hiermit abgeschlossen.
