What does the red Fault LED flashing with no other LEDs on mean?
If only the Fault LED is quick flashing and all other LEDs are off, this indicates an over-temperature condition. You should let the unit cool down for some time or improve ventilation around the unit. A minimum air gap of 150mm around the unit is required. (Page 4)
