to +10%
1) The adjustable frequency drive can run at -25% input voltage with reduced performance. The maximum output power of the
adjustable frequency drive is 75% if input voltage is -25% and 85% if input voltage is -15%.
Full torque cannot be expected at AC line voltage lower than 10% below the lowest rated supply voltage of the adjustable
frequency drive.
