The 3AXD50000296767: Rated for IP55 and NEMA Type 12 enclosures, meaning it handles dust, hose-down, and the kind of wet mechanical-room floors you find in commercial HVAC. The R2 frame keeps the footprint manageable for wall-mounting without a dedicated cabinet.
Ratings that matter for the install
Standby loss sits at 14 W — low enough that you don't need to factor extra ventilation for idle time, but not negligible if you're counting every watt on a battery-backed bus. Ambient temperature is capped at 40 °C for full rating. Above that you derate per the drive's thermal curve — standard for any wall-mount unit in a warm mechanical room.
