This parameter represents the voltage value at which the undervoltage alarm relay will be activated.
It can be edited by short pressing the ENTER key each time to increase the value by 0.1V. This value
must always be lower than the Undervoltage alarm off value.
Now that all parameters are set, the ENTER key must be pressed for two seconds to save the settings
and jump back to the normal operating mode.
