*1 Operation only with special starting circuit via 12-pole winding.
*2 The 2-pole starting current for main hoist and the rated current for the travel motor were taken into
consideration when selecting the main fuse.
*3 The motors are designed for rated voltage ranges. In accordance with EN 60034 a voltage tolerance of
±5 % and a frequency tolerance of ±2 % apply on top of the rated voltage ranges. The maximum current
occurring in the rated voltage range is given.
