● Local maintenance refers to operations performed after a USB flash drive, Bluetooth
module, WLAN module or USB data cable is inserted into the USB port of the SUN2000.
For example, local maintenance includes configuration 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, WLAN 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, WLAN
module or USB data cable is removed, the LED shows the alarm status.
