For charging stations with phase switching: Is Phase Switching active?

3. Commissioning

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

You should also read and familiarize yourself with the "Configuration Manual" for the Salia PCB:
Configuration Guide — Salia PCB

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.

Tap or click the submenu item to access the following main screen.

The following options are available here:

Manual Phase Switching, 1- or 3-phase
Automatic Phase Switching

5.8.1. Manual Phase Switching

Use Case

One scenario would be to use the limited PV production to charge the vehicle anyway by manually switching to single-phase charging.

Switching During Charging:
When manually switching from single-phase to three-phase and vice versa, the hardware undergoes a 30-second switching process each time.

Please wait during this switchover.
During these 30 seconds, the charging power is reduced to 0 kW, and then the switchover occurs.

When performing phase switching, vehicles behave differently depending on the model.
Your vehicle must support phase switching.

5.8.2. Automatic Phase Switching

In addition to the Manual Phase Switching (1- or 3-phase), there is the option of Automatic Phase Switching:

The phases are automatically switched based on the charging power. This allows even a small amount of excess PV power to be utilized.

The Fast Charge mode always uses 3 phases.
Your vehicle must support dynamic phase switching.

The switching times depend on the wallbox and its internal logic.
The phase change may take a few minutes.
