Set the termination resistor and node address via the parameter bank; no external converter needed if the BAS speaks Modbus RTU over RS-485. ## Certification and compliance The drive carries CE, UL, and CUL markings and meets RoHS 6. That satisfies the common requirements for North American and European installations. The UL listing is specifically the file number for variable-speed drives; confirm the marking on the nameplate matches your local AHJ requirement.","metaTitle":"Mitsubishi FR-A840-22K-1 VFD, 22 kW, 44 A, Three-Phase","metaDescription":"Current-production VFD for 22 kW motors, 44 A output at 400 V three-phase.
