● Local maintenance refers to the operation of inserting a WLAN module or USB data
cable into the USB port of the device. For example, connecting to the SUN2000 app
through the WLAN module.
● If alarms are generated during the local maintenance, the fault/maintenance indicator
shows the local maintenance state first. After the WLAN module or USB cable is
removed, the indicator shows the alarm state.
