You can browse the different values available in this form for the connector's Type, Current Type, and so on.
If you need to change values, do so and click Edit. Later, if needed, you can come back to the initial values by choosing the Use System Configuration button. Remember that the voltage and number of phases of the connector must match with the electrical properties of the site area.
If you don't need to change values, keep your connector synchronized with the charging station's system configuration by choosing Cancel.
