Local maintenance refers to operations performed after a USB flash drive, Bluetooth module, or
USB data cable is inserted into the USB port of the SUN2000. For example, local maintenance
includes data import and export using a USB flash drive, and maintenance operations on the
SUN2000 app installed on a device connected to the SUN2000 by a Bluetooth module or USB data
cable.

If an alarm occurs during local maintenance, the Alarm/Maintenance LED shows the local
maintenance status first. After the USB flash drive, Bluetooth module, or USB data cable is removed,
the LED shows the alarm status.
