14.5.4 Settings Menu
The configuration parameters in the Settings menu are password protected. Among the most
significant values you can select, note the neutral threshold (values 50%, 100%, 150%, 200%), the
external toroid size (values 100A, 250A, 400A, 800A), the mains frequency at the installation (values
50Hz, 60Hz). For a more detailed description of the settings for the modules, refer to the
documentation on the modules (ch. 15).
