What is the flow rate for ATV61/71 ratings greater than 90 KW?


The drive has a fan for cooling the power components. The air is circulated from the bottom to the top of the unit via a duct (the duct is
shown shaded gray on the diagram below).
The drive dissipates a great deal of power which must be evacuated to the outside of the enclosure.
Air inlets and outlets must be provided to ensure that the flow of air in the enclosure is at least equal to the value given in the table below
for each drive.
The flow rate is as below
