DC-UPS - 24V, 20 A, 480 W Reference Manual
This light-emitting diode (LED) indicates that charging or buffering is not
possible.
Check Wiring:
The light-emitting diode (LED) is on solid when a failure in the
wiring, battery, or battery fuse is identified.
Input Voltage:
A single flash indicates that the input voltage is >30V or the
input voltage is too low for the adjusted buffer voltage. The input voltage must
be at least 1V higher than the selected buffer voltage.
Temperature:
A double flash indicates that the temperature of the DC-UPS is
too high (> 70 °C) or that the temperature of the battery is too high (> 50 °C) or
too low (< -10°C in setting <10 Ah). Battery temperatures indications require a
connected battery temperature sensor.
