What this order code is
ACS550-U1-023A-4+K467 is a U1-frame ACS550 series AC drive, identified by the -023A-4 current class and carrying the +K467 factory option suffix on the nameplate. Listed at 8.53 kg on the spec sheet, the unit is a one-person lift onto a backplate but still wants the chassis fixed on all four corners.
Where it fits a load
An ACS550 U1 frame is sized for general-purpose motor loads in industrial cabinets — pumps, fans, conveyors, mixers — where the panel builder wants the standard ACS550 parameter set. The +K467 option suffix tails the base drive, so the integrator specifying it from the BOM line should read the +K467 against the option-key sheet before assuming the I/O variant on this build.
Panel-fit note for the integrator
Drop the unit onto a U1 backplate pattern and leave clear air above and below the heatsink — the 8.53 kg mass is fine for one installer on a step ladder, but the cabinet layout needs the U1 spacing rule respected or the thermal derate kicks in early and the parameter set will flag an overtemperature fault long before the motor complains.
