Both types would be possible, for the same conditions. * Instructions for planning and design : The motor is designed for a starting current of max. double rated current. The max. starting time is 30 seconds. The starting cycle has to be supervised. An automatic system transfer is not admissible. After a voltage failure > 100 ms the motor has to be started by the motor starter again. The max. voltage unsymmetry is long-term 1 %. The optimal humidity is between 8 and 15 g/m³.
