5) If the mains voltage is low, the nominal torque of the motor will be lower.
6) The phase rate of rise (dv/dt) depends on the line capacity.
7) The efficiency at the nominal point of the frequency inverter varies between 98 percent for high power outputs and
95percent for low outputs, depending on the inverter's nominal power.
8) The values are for orientation purposes only. The value refers to the nominal duty point (50Hz) only. Also refer to the
pump's noise characteristics. They, too, are documented for nominal duty operation. Other values may occur during
variable speed operation.
