Thecontactor should only beused as a safety device fordisconnecting power to thedrive.Line/LoadReactor(Optional)To improve the power factor.An AC Reactor may benecessary when capacity isabove 1000 kVA, and thewiring distance is within 10m.EMI Filter(Optional)Used to reduce theelectromagneticinterference.BrakingResistor(Optional)Used to reduce stoppingtime of the motor. Pleaserefer to the Breaking Resistortable in Appendix C forspecific Braking Resistors.
