2 = Middle inverter module in enclosure sizes F12
or F13.
2 = Right inverter module in enclosure sizes F10
or F11.
2 = Second frequency converter from the left
inverter module in enclosure size F14 or F15.
3 = Right inverter module in enclosure sizes F12
or F13.
3 = Third from the left inverter module in
enclosure size F14 or F15.
4 = Far right inverter module in enclosure size
F14 or F15.
5 = Rectifier module.
6 = Right rectifier module in enclosure size F14 or
F15.
