Mount it in any orientation. The housing is rated IP20 with conductors connected, IP40 in the handle area, so it's fine inside a clean control cabinet but not for washdown zones. Vibration resistance is 50 m/s² at 25 to 150 Hz and 60 m/s² at 35 Hz — tough enough for machine-mounted enclosures on compressors or conveyors.
