What the part is
The ACS355-01E-09A8-2: Mechanically, the drive occupies frame R2 in the ACS355 family, with an overall envelope of 105 mm wide by 169 mm tall by 165 mm deep and a unit mass of 1.7 kg — the kind of footprint that drops onto a standard module-mount plate next to a contactor and a brake resistor. The enclosure rating is IP20 / Open Type NEMA, which means the unit relies on the host cabinet for ingress protection; it is not a stand-alone wall-mount drive.
What the ratings mean for the fit
The 200 to 240 V input window is the one that decides whether this drive fits the BOM. The -01E designation targets low-voltage single-supply cabinets; higher-voltage mains should look at the -03E peer SKUs instead. IP20 with an open-type NEMA designation means the drive assumes a clean, dry cabinet interior. If the application is washdown, dusty, or outdoor, the enclosure strategy has to be solved at the panel level — gasketing, filtered fans, and a thermal budget that keeps the drive on its derating curve — rather than relying on the drive itself to seal out the environment. At 1.7 kg in an R2 frame, the drive is a one-person lift and a screw-down module mount, which keeps the panel-builder's install sequence straightforward. There is no heatsink mass to lean on for high-ambient operation; derate per the manual curve as the cabinet interior climbs.
Where this class of drive is used
Machinery drives in the Motors & Motor Controls / Drives / Motor Drives category are the typical variable-frequency front end for fractional-horsepower conveyors, small pumps and fans, packaging indexing tables, and material-handling sections where the OEM needs adjustable speed and soft starts from a compact module inside the machine's main panel.
