What lands on the BOM
The ABB ACS550-U1-077A-6 is an AC drive on the Motors & Motor Controls / Drives / Motor Drives line. Chassis weight is 40.82 kg, a two-person lift.
Integration notes for the commissioning crew
On the wiring side, the drive drops into a standard motor-control cabinet with the same gland-plate and DIN-rail layout as other ACS550-U1 frames, so the field-service crew can move it through the standard commissioning sequence — power off, verify DC-link discharge, land the motor leads, then bring the bus up. Grounding and EMC practice follow the ACS550 family convention: short, bonded grounds at the cabinet entry, with the motor cable shield landed at both ends to keep the drive's own switching noise out of adjacent analog loops. The chassis mass of 40.82 kg is what governs handling and lift rigging, not the electrical fit.
