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
