| | | Ratings definition The ratings (torques) listed in the table apply to continuous operation (S1) with nominal speed at a maximum ambient temperature of 40°C with the machine being installed below 1000m a.m.s.l. If motors are to be operated in an ambient temperature of more than 40 °C or altitudes above 1000 m a.m.s.l., the required list nominal power Pl (list torque Mn) results from the product of the factors ki, k specified in the table and the required power P (torque M). | | |

| | | For ambient temperatures above 40 °C and enclosed installation of motors, it is absolutely necessary to contact the manufacturer, because design changes may be necessary. If, with increasing site altitude above 1000 m, the ambient temperature decreases by approx. 10 °C per 1000 m increase in altitude, no power correction is necessary. | | |

| | | Winding isolation and temperature rise All machines of this series are designed in insulation class F according to EN 60034 for a permissible winding temperature of105 K at a room temperature of up to 40 °C. The insulation is resistant against gases and vapours of combustible materials and it meets the requirements placed on a moisture-proof and tropical insulation. A special insulation that can be obtained for an extra charge is necessary if concentrated acid vapours and metallic powders occur, with a permanent relative air humidity of more than 80% and as protection against termite and mould fungus attacks. In the case of converters with a DC link voltage > 500 V, the cables between the industrial converter and the motor must not be longer than 20 meters. For longer cables, additional measures (e.g. motor filters) must be provided. The maximum permissible terminal voltage is 1000 V. | | |
