Probable cause:
Over Temperature occurs when the ambient temperature is not maintained or due to Heatsink Temp Sensor failure.
Possible Solution:
Maintain operating temperature between 0° to 40°C at full load and 40° to 50°C linearly derated to 80% of maximum load capacity.
Do not operate UPS where there is excessive dust or where the temperature or humidity is outside specified limits.
Do manual restart of UPS by switching off the output, disconnecting the battery cable at the rear panel, turning off the input power supply, and reconnecting the battery cable and input, this should make the fault to be clear.
In case of the error persists even after trying the above troubleshooting, log the complaint.
