A cooling fan must be fitted at appropriate location in the cabinet for heat dissipation. The braking resistor must be installed in a separate cabinet and cannot be installed with the inverter, braking unit or other devices because it will generate high heat.

Page 13: Defining The Peak Brake Current I
User Manual BR100 Braking Unit 6. Selection of Braking Unit The braking unit is an electric device designed for short-time and intermittent work, which is with a limited working capacity when under big current for a long time. Proper selection can protect braking unit from damage caused by high heat due to over-current. -
Page 14: Braking Resistor
User Manual BR100 Braking Unit 7. Braking Resistor User can choose different resistance and power ratings based on real needs (But the resistance cannot be less than the minimum brake resistance.) The braking resistor should be selected based on motor power ratings, and it could vary with system inertia, deceleration time, and potential energy load. - Page 15 User Manual BR100 Braking Unit Install the braking resistor on the top if it is installed with other devices in the same cabinet. Choose heat-proof cable since temperature of braking resistor will be ＞150℃ in the process of brake.
