The ABB ACS880-M04-078A-5 is the M04 multi-mount order code at 078 A. Input is listed as 3~380-500 V, which sets the supply window for the panel feeder and breaker. At 21.32 kg the unit is a two-person lift and lands on a cabinet cross-member, not on a backplate hanger. Plan the handling path before the crate shows up at the panel-build bay.
Mounting and EMC discipline on the ACS880-M04
ACS880-M04 multi-mount drives are placed close to the motor feeder to keep the motor cable short — long pigtails between the drive output and the motor terminal box pick up the common-mode noise the inverter throws onto the cable shield. Ground the shield at the cabinet gland end and float the motor end, the way the rest of the ACS880 install base is wired.
Cross-shop against the wall-mount ACS880-01
A buyer weighing this part against the wall-mount ACS880-01-065A-5 is comparing the M04 multi-mount frame versus the 01 wall-mount frame. The 01 candidate lists at 23.13 kg; the M04-078A-5 lists at 21.32 kg. The decision is mechanical — cabinet footprint and motor cable routing — not electrical class.
