5-4 Associated EquipmentAC30 series Variable Speed InverterAC Motor ChokesThe maximum rate of rise of Volts (dv/dt) present on the motor terminals of the inverter, can be as high as 10,000V/s. This can bereduced by adding a motor choke in series with the motor.Installations with long cable runs may suffer from nuisance overcurrent trips, refer to Appendix C Compliance - Cabling Requirements formaximum cable lengths. An output choke may be fitted in the inverter output to limit parasitic capacitive current to earth. Screened cablehas a higher parasitic capacitance to earth and may cause problems in shorter runs.
