Suggested Actions

1. 1Check to see if the cooling is working
2. 2Disconnect the load at the output
3. 3Disconnect the primary power supply if the alarm persists
4. 4Check that the heaters are working
5. 5Wait until the system temperature rises to the desired level before operating normally
6. 6Exit the current operating mode
7. 7Perform a maintenance charge until the battery is fully charged
8. 8Decrease the power consumption
9. 9Shut down the operating mode that is running
