Losses, cooling data and noise
The air flow direction is from bottom to top.
This table shows typical heat loss values, required air flow and noise at the nominal ratings
of the drive. The heat loss values can vary depending on voltage, cable conditions, motor
efficiency and power factor. To obtain more accurate values for given conditions, use ABB
DriveSize tool (http://new.abb.com/drives/software-tools/drivesize).

The cooling air temperature rises 30 degrees Celsius when it goes through the drive module
if the temperature of the input cooling air is 40 degrees Celsius.
Typical power cable sizes
The table below gives copper and aluminum cable types with concentric copper shield for
the drives with nominal current. See also section Terminal and entry data for the power
cables (page 187).
