This alarm is only for enclosure size F frequency converters.
It is equivalent to Alarm 27. The report value in the alarm
log indicates which power module generated the alarm:
1 = Left most inverter module.
2 = Middle inverter module in enclosure sizes F12
or F3.
2 = Right inverter module in enclosure sizes F10
or F11.
2 = Second frequency converter from the left
inverter module in enclosure size F14.
3 = Right inverter module in enclosure sizes F12
or F13.
3 = Third from the left intverter module in
enclosure size F14.
4 = Far right inverter module in enclosure size
F14.
5 = Rectifier module.
6 = Right rectifier module in enclosure size F14.
