Motor cooling with fresh air via air duct. The motor protection is provided by customers. Service switch serial on cooling duct. For speed control of single speed motors use combination of frequency converter and appropriate filter to motor side (sine or du/dt), respectively observe instructions. Tested to 400°C/2h together with frequency converter. However, we recommend bridging of frequency converter in case of fire to eliminate possible risk of malfunction of frequency converter. In case of fire all motor protective devices and thermal protections in frequency converter must be bridged or disabled to guarantee functional capability. At frequency controlled units additional EMC protection could be needed (on request). When choosing AES control accessorie please observe serial connecting capability of the service switch of the DVV fan (instructions). Higher connecting capability on request.
