Enclosure & mounting
Wall-mounted in a NEMA 1 (IP21) enclosure, frame size R7. IP21 means protected against solid objects over 12 mm and dripping water — fine for a dry pump room or treatment gallery, but not for washdown zones. NEMA 1 keeps the electronics behind a ventilated sheet-metal cover; no conduit knockouts are pre-punched for the R7 frame, so plan for gland-plate entry on-site.
Supply & frequency range
Input accepts 380-500 VAC at 47.5-63 Hz, covering 50 Hz and 60 Hz grids worldwide. The wide frequency tolerance means it handles weak generator supplies or off-nominal conditions on remote well sites without nuisance tripping.
