Description

Motor	AC 1x230V/50Hz: compact asynchronous fan motor with external rotor and squirrel-cage. The electric motors are housed inside the impeller (so-called motor impeller) and are optimally cooled by flowing air during operation. They are characterized by a small inrush current and the possibility of voltage regulation. For motor thermal protection, see chapter Electric motor protection. The single-phase electric motors are equipped with a potted starting capacitor mounted next to the terminal block with ingress protection IP 54.
Terminal block	The electrical installation is terminated by a terminal block with ingress protection IP54. The single-phase electric motors are equipped with a potted starting capacitor mounted next to the terminal block.
Installation	The fan may transport air without solid, fibrous, sticky, aggressive and explosive admixtures. The air must not contain chemicals that cause corrosion or decompose zinc, aluminium or plastics. The maximum permissible transported air temperature must not exceed +40 °C (for the three-phase fans), or +60 °C (for the single-phase fans). The RF fans can only be operated, transported and stored in the basic horizontal position (suction from below). The device can be used without additional measures in normal areas (IEC 60364-5-51, or ČSN 332000-5-51 ed.2, ČSN 332000-3) with extension to outdoor areas and areas not protected from atmospheric influences with a temperature range of -30 to +40 °C.
