Page 214.5 Alarm codesUsing a sophisticated self-diagnosis system, the UPS is able to check its own status and any anomalies and/or faultswhich may occur during normal operation and display them on the display panel. If there is a problem, the UPS signalsthe event by showing the code and the type of active alarm on the display.ALARMS“ Minor” problems which reduce performance or prevent certain functions from being used.CODE DESCRIPTIONA007 Fans blockedA107 Cable connection errorA10A Unbalanced input voltages (three-phase input)A806 E.P.O control activeA80E Overload: load > 105%A810 Load percentage greater than the user threshold setA60D Batteries missing or Battery Box missing or not connectedA802 Low batteryFAULTSFaults are normally preceded by an alarm signal and their scale leads to the power-off of the inverter and the load beingpowered by the bypass line.CODE DESCRIPTIONF002 UPS FaultF004 Dissipator over temperatureF302 F303 Capacitor bank undervoltageF300 F301 Capacitor bank overvoltageF304 Unbalanced capacitor bankF305 Failed capacitor bank soft startF70D Inverter overvoltageF805 Short circuitF704 Failed inverter soft startF70C Inverter undervoltageF808 Output overload faultF811 Negative output power
