3.8 Multi-iDrive installation with regenerative loads
Notes:
If parallel connecting the DC busses of different capacity inverters;
Must power up in sequence: Largest capacity first → smallest capacity last.
DC fuses and/or other precautions may be necessary.
Never connect ‘+’ terminals to ‘–‘ terminals or damage will occur.
If in doubt consult your local iDrive distributor or dealer.
If all iDrives are of the same voltage rating, the DC bus connections of each can be
connected together in parallel. Regenerated braking power from stopping of high inertia
loads can then be dissipated or partly dissipated between all of the paralleled iDrives.
If more energy requires dissipating, a braking module and resistors can be connected as
shown above.
