Drive Overview
The Fuji FRN007AR1L-2U is a FRENIC-HVAC series variable frequency drive rated for 7.5 HP on a 3-phase 230 V supply, housed in a NEMA Type 12 enclosure for dust and drip protection.
The 7.5 HP rating at 230 V three-phase tells you this drive is sized for a motor drawing roughly 22 A full-load current — typical for a medium HVAC fan, pump, or compressor in a commercial building. The NEMA Type 12 enclosure means it's suited for indoor environments where falling dirt, dust, and non-corrosive liquids are present; no need for an additional panel in a clean mechanical room. The FRENIC-HVAC series is purpose-built for fan and pump applications, with built-in PID control, fire mode override, and energy-optimizing V/Hz patterns. This isn't a general-purpose drive adapted for HVAC — it's designed around the load profile.
The UL listing (per the description) means it carries a Nationally Recognized Testing Laboratory mark for the US and Canada, which simplifies panel acceptance for inspectors and code compliance.
