iDrive2 inverters
connecting them with the inverter.
 Do not connect the braking resistor with other terminals except for PB and (-). Damage to
the inverter or braking circuit or fire may occur.
 Connect the braking device with the inverter according to the diagram. Incorrect wiring may
cause damage to the inverter or other devices.

Note:
Select a resistor with wattage and resistance rating as specified in the table above.
The braking resistor may increase the braking torque of the inverter. Above table is measured at 100% braking
torque, 10%, 50% and 80% braking usage rate, the user can select braking level according to duty cycle.
 Do not use brake resistor with a resistance below the minimum value specified for the particular
drive. The drive and the internal chopper are not able to handle the overcurrent caused by the
low resistance.
 Increase the power of the braking resistor properly in accordance of the duty cycle (the duty
cycle is more than 10%).
C.7.2 Connection of external brake resistor
Install all resistors in a place where they have air clearance.
 The materials near the brake resistor must be non-flammable. The surface temperature of the
resistor can be extremely high, ensure sufficient ventilation for heat dissipation.
Only external braking resistor is needed in IMO XKL.
