 Local maintenance refers to operations performed after a USB flash drive, a WLAN module, a
Bluetooth module, or a USB data cable is inserted into the USB port of the solar inverter. For
example, local maintenance includes data import and export using a USB flash drive, and connecting
to the SUN2000 app over a WLAN module, a Bluetooth module, or a USB data cable.
 If the alarming and the local maintenance happen concurrently, the alarm/maintenance indicator
shows the local maintenance state first. After the USB flash drive, WLAN module, Bluetooth
module, or USB data cable is removed, the indicator shows the alarm state.
