*1 For the FR-A820-03800(75K) or higher, the FR-A840-02160(75K) or higher, or whenever a 75 kW or higher motor is used, always connect a DC
reactor (FR-HEL), which is available as an option. (To select a DC reactor, refer to
capacity.)
When a DC reactor is connected to the FR-A820-03160(55K) or lower or the FR-A840-01800(55K) or lower, if a jumper is installed across
terminals P1 and P/+, remove the jumper before installing the DC reactor.
