The RS485 two-wire cable, which is required to connect the Modbus/RTU communication connection to the meter, is not included in the scope of delivery!

2.2. Prerequisites

The following is required to use the charging station:

Symphon-E App eCharge Hardy Barth cPµ2 Pro Charging Station

The "Symphon-E App eCharge Hardy Barth cPµ2 Pro Charging Station" is not included in the scope of delivery. This must be purchased separately if not already available.

3. Commissioning

To install the Hardy-Barth charging station, please follow the instructions in the "Installation and operating instructions cPμ2 charging station".
Operating instructions cPμ2 German (v1.0)

The "Configuration Manual" for the Salia board should also be read and internalized:
Configuration manual — Salia board

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.

The plug connection for the LED display can be disconnected if required. This makes it easier to work on the charging station during commissioning.

We recommend checking the plug connection to the left of the Ethernet port on the Salia board, as in our experience this is often loose.

Once the charging station has been installed and configured, it must be connected to the customer network via the network interface (LAN) on the Salia board.

Figure 1. Network interface (LAN) - Salia board

3.1. Connecting the meter

Connect the meter as shown below:

Figure 2. Connected meter

Use the enclosed instructions for this:

Figure 3. Meter connection

Make sure that the meter is installed the right way round: OUT must point towards the charging station, IN towards the sub-distribution board.

Establish the communication connection to the meter as follows:

Figure 4. Establishing the communication connection

The negative contact of the cable must be connected to contact A on the meter and to contact 22 (top) on the Salia board. The positive contact of the cable must be connected to contact B on the meter and to contact 23 (bottom) on the Salia board.

3.2. Configuration

By default, the charging station can be reached under the IP address 192.168.25.30 (or 169.254.12.30).

To reach the charging station from your notebook/PC, it is necessary to set up a static IP address in the same subnet (e. g. 192.168.25.1) in the network adapter settings.

To do this, connect the Salia board to your device (here: notebook) via the RJ45 socket, as shown below:

Figure 5. Connecting the Salia board to the notebook

Open your web browser to access the web interface. To do this, enter the following IP address: 192.168.25.30

If problems occur in step 2, proceed as follows:

Open the "Network and Sharing Center" under the system settings of your PC.
Click on LAN connection.

In the newly opened window, click on Properties
In the new window, double-click to open the "Internet Protocol Version 4 (TCP/IPv4)" item
(see graphic).
Alternatively, select "Internet Protocol Version 4 (TCP/IPv4)" in the open window and then click on "Properties"

In the next window, select "Use the following IP address" to enter the IP address 192.168.25.1 and the subnet mask 255.255.255.0 as shown in the picture below. The entries for the DNS server can be left blank.

Confirm the entries. Then switch off the power to the wallbox once, wait a few seconds and allow the wallbox to reboot.

The charging station can then be configured via the web interface. To do this, enter the IP address of the charging station (192.168.25.30) in the address bar of the browser. The web interface then appears as shown below:

Figure 6. Web interface

The network settings can be checked here:

Figure 7. Network settings

3.3. Configuration of the meter

It must be ensured that the meter is activated:

Figure 8. Meter

If this is not the case (grayed out symbol), it must be activated manually. To do this, double-click in the free area next to System configuration:

Figure 9. Hidden menu

An extended view with further configuration options then opens. The meter can be activated under Advanced Options:
