Motor The roof fan is by type equipped with one of two types power unit:
AC 1x230V/50Hz: compact asynchronic fan engine with external rotor and squirrel cage. Electroengines are saved into impeller and they are optimally cooled via air flow. With a low residual current and voltage control options.Thermal fuse via Protection of the electroengine. Single-phase electroengines are equipped starter capacitor, which is located next to terminal block, protection IP54.
AC 3x400V/230V 50Hz (Y/D): flange IEC asynchronous engine squirrel cage. Terminal is located on the engine body. Electric engines are kept out of the airflow and are protected against direct contact with the air. The engine cooling system to ensure internal channels. engine protection class IP55. The engine thermal protection performed by the thermal exited into the cable, see chapter engine protection. Engine insulation system corresponds to temperature class F insulation with warming in class B. Thermal insulation class is determined by the engine manufacturer and is listed on the rating plate of the engine.Terminal block Electroinstalation is finished with terminal, protection IP54. Single-phase electromotors are equipped with starter capacitor, which is saved next to terminal block. Schema of the connection are on the list 74.
Installation The fan must be transported air without solid, fibrous, sticky, aggressive and explosive impurities. Air mass may contain chemicals that corrode or degrade zinc, aluminum or plastics. The maximum allowable air temperature must not exceed + 40 °C (1-phase fans), respectively. + 60 °C (single-phase fans). Fans RF can be operated, transported and stored only in the horizontal position (suction from below). The device can be used without additional measures in areas of normal (IEC 60364-5-51, resp. 332000-5-51 ed.2 CSN, CSN 332000-3) extending to the outdoor spaces and spaces unprotected from the weather with a temperature range between -30 to + 40 °C.
