Note:
1. The VFDs of 220V (18.5–55kW), 460V (≥37kW,), and 575V (≥22kW) supports external DC
reactors and external braking units, but it is necessary to remove the copper tag between P1 and
(+) before connecting. DC reactors and external braking units are optional.
2. The VFDs of 220V (≤15kW), 460V (≤30kW,), and 575V (≤18.5kW) supports external braking
resistors which are optional.
3. The VFDs of 575V supports external DC reactors and external braking units, but it is necessary to
remove the copper tag between P1 and (+) before connecting. DC reactors and external braking
units are optional.
