In FEMS, go to Settings to open the App Center and install FEMS App by following these instructions: General installation instructions for FEMS Apps.

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

Required fields are marked with an *.

Select the phase rotation. This setting must match the phase rotation of the charging station.

The phase connection L1_L2_L3 is selected as standard.

Check your entries and make sure they are correct. Otherwise, the app will not work properly.
After you have configured the settings in FEMS, complete the installation by clicking INSTALL APP.
