The FRN0013F2S-4C is a Fuji Electric FRENIC Series high performance inverter rated for three-phase 400V supply, with an amperage rating of 0013 (13 A). The enclosure is S = Basic type (IP20/IP00), meaning the drive body is protected against solid objects larger than 12 mm (IP20) while the power section is open-frame (IP00) — standard for panel-mount installations where the cabinet provides the environmental seal.
The 400V three-phase input means this inverter is sized for standard European or Asian 380–480 VAC industrial mains without a step-down transformer. The 13 A rating governs the motor current it can deliver — match it to a motor whose full-load amps fall at or below that figure. The IP20/IP00 enclosure tells the panel builder that the drive needs a cabinet with at least IP54 to keep out dust and moisture; the power terminals are live and require finger-safe covers or separation from operator access.
