Question about Inverter KEB COMBIVERT F5
Posted by Anonymous on
E.PU is a general power stage failure.
Without knowing the part number of the actual inverter with the problem it is difficult to speculate what the actual problem is.
One thing to do is to check if the fan is operating. Some of the older F5 inverters utilized a feedback loop so that the inverter could tell if the fan was functioning properly. If the fan was not functioning the inverter would trip into E.PU.
