The Fuji FRN002AR1M-4U is a FRENIC-HVAC series drive rated for 3-phase 460 V input, 2 HP output, housed in a UL/NEMA Type 1 enclosure. This is the standard catalog variant for HVAC fan and pump applications where the drive sits in a clean, indoor panel environment — the Type 1 rating means it's drip-proof but not washdown-rated, so keep it out of direct hose spray or outdoor weather.
The 2 HP / 460 V three-phase rating sizes this drive for a standard 2 HP induction motor on a 460 V line — common for small HVAC fans, condenser pumps, or cooling tower drives. The FRENIC-HVAC series is tuned for variable-torque loads (fans and centrifugal pumps), not constant-torque conveyors or extruders; the drive's V/Hz pattern and auto-tune routines expect a quadratic torque curve. The UL/NEMA Type 1 enclosure means it's intended for indoor installation where no condensation or falling dirt is present — if the drive goes into a mechanical room with washdown hoses, you need a Type 12 or 4X variant from the same series.
