„Parallel units“
The permissible output current in parallel mode is reduced (due to current division between the power sections) by 10 % as compared to the sum of the rated currents of the separate power sections.
1)For units from product status A2 and onwards (labelling on the unit at the coolant connection).
2)If the cooling circuits of the two converters are connected in parallel.
3)A rectifier/regenerating unit consists of two converters in separate housings.
