* Note)
1) The above graph is only applied when the inverter is operated in the allowable temperature. Pay
attention to the air cooling when the inverter is installed in a panel box, and the inside temperature
should be within an allowable temperature range.
2) This derating curve is based on inverter current rating when rated motor is connected.
