The speed selection takes place via the 0-10 V control signal (e.g. potentiometer PU/PA, accessories). Cable length between FU-BS and fan over 10 m is possible. No additional EMC shielding of electrical cables required. The fans including motor need no special EMV precautions for the frequency inverter operation. The FU-BS is fixed at its rated current. When using the frequency inverter with integrated sine filter standard fans/motors are applicable.
