The Fuji Electric FRN0072F2S-4C is a FRENIC Series High Performance Inverter rated for 7.2A on a 400V three-phase supply. The 'S' in the order code denotes a basic enclosure type — IP20/IP00 — meaning the drive body is protected against touch and solid objects larger than 12 mm, but the internal bus and control board are exposed once the cover is off. That's standard for panel-mount drives; you'll need a separate enclosure if the environment has conductive dust or washdown.
The 7.2A rating is the continuous output current for the drive's nominal motor load. On a 400V three-phase supply, that works out to roughly 3.7 kW (5 HP) for a standard induction motor. The IP20/IP00 enclosure means the drive is designed for a clean, dry electrical panel — not for direct mounting in a washdown or dusty area. If the application is on a lube route or near rotating equipment, plan for a separate NEMA 4X or IP54 cabinet.
