The ACS880-01-061A-7: Listed mass is 44.91 kgs, which is the figure a single installer has to handle and the cabinet floor has to carry when the drive is floor-mounted under the ACS880-01 frame — call it out for lift planning, not for selection.
Where this class lives in the panel
ACS880-01 is the wall-mount single-drive form factor in the Motor Drives line; at 44.91 kgs the unit is a two-person floor-mount proposition, not a DIN-rail part. For a 525-690 V supply the typical placement is on the back wall of a low-voltage MCC section with cable entry from below; the input voltage class is the headline constraint that decides cable gland sizing and clearances above the drive, not the horsepower number on the nameplate.
