7.1.1 Operation LEDs
Configuration of the status LED ( )
The status LED can display the following statuses:
• Status of the Cluster Controller
• Status of the connected inverters
• Status of the plant communication
• Status of the grid management
In this document, the only states described below are those that the status LED can adopt upon initial
start-up (for a complete description of the states, see the Cluster Controller user manual).
• If the status LED is not glowing green after commissioning, refer also to the event log of the
Cluster Controller to determine the precise cause of the fault. The details of the respective fault
are logged in the event log (see the Cluster Controller user manual).
LED Status Cause and corrective measures
All Off The Cluster Controller is not connected to the voltage
supply.
Corrective measures:
• Connect the Cluster Controller to the voltage
supply (see Section 6.13).
The voltage supply is reverse-connected or the top-hat
rail power supply unit is defective.
Corrective measures:
• Ensure that the voltage supply is correctly
connected (see Section 6.13).
• If the voltage supply is correctly connected,
replace the top-hat rail power supply unit.
