The Fuji FRN002AR1L-5U is a FRENIC-HVAC variable frequency drive rated for 3-phase 575 V input, 2 HP output, housed in a UL/NEMA Type 12 enclosure. This is the drive for a 2 HP motor on a 575 V line — common in North American commercial HVAC and light industrial applications where the Type 12 enclosure keeps dust and dripping liquids out of the panel.
The 575 V three-phase input matches the standard North American 600 V class motor supply — common in 480 V / 575 V plants. The 2 HP output rating governs the motor it can drive; oversizing is not needed here if the motor nameplate matches. The UL/NEMA Type 12 enclosure means it is rated for indoor use where dust, falling dirt, and dripping non-corrosive liquids are present — think mechanical rooms, rooftop unit enclosures, or factory floor cabinets not rated for hose-down.
