Dimensions, Weights and Noise

The dimensions and mass for the ACS550 depend on the frame size and enclosure
type. If unsure of frame size, first, find the "Type" code on the drive labels. Then look
up that type code in the "Technical Data" on page 127, to determine the frame size.
A complete set of dimensional drawings for ACS550 drives is located in the ACS550
Technical Reference manual.
See table heading "Hardware Description" on page 21.
Outputs
