[ When installing a DC reactor (option), remove the common bar between ¨1 and ¨2 terminals
(provided as standard) and connect a DC reactor with the terminals.
] When using the braking resistor unit, set constant L3-01 to “0” (overvoltage prevention selection
is disabled). If it is not changed, the inverter may not stop within set decel time.
