Where this drive sits next to its siblings
The U1-frame ACS550-U1-059A-4+B055 weighs 36.29 kgs and the ACS550-U1-072A-4+B055+L512 weighs 34.02 kgs, putting the 43.09 kgs PD frame clearly above the U1-frame mass band. A panel designed around one frame will not accept the other without re-checking cabinet footprint, motor cable gland pattern, and cooling clearance.
