
Local maintenance refers to operations performed after a universal serial bus (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 connecting to the
SUN2000 app over a Bluetooth module or USB data cable.

If alarming and local maintenance happen concurrently, the alarm/maintenance indicator shows the
local maintenance state first. After the USB flash drive, Bluetooth module, or USB data cable is
removed, the indicator shows the alarm state.
