• CONTROLLED STAR DELTA • Star and triangle loops are equipped with the
functions of independent basic voltage, and setup of start and current limitation parameters
• Maximal alterations on the existing circuit are not necessary

• CONTROLLED STAR DELTA
• Before the soft start function of the star loop is set to finish the timing at the time of start, the voltage should be at the highest value- or else the “IntelSteer Power Save” will stop rather than shift to the triangle loop and start normally
