2) DB Resistor (For External Installation, Optional)
DB transistor is integrated for ratings below 7.5kW. Install the external DB resistor if necessary. However, DB
transistor is not provided for the ratings above 11kW, installing both external DB unit and DB resistor are required.
See the following table for more details (ED: 5%, Continuous Braking Time: 15 sec). If Enable duty (%ED) is
increased to 10%, use the external DB resistor having twice Wattage rating.
