The role of braking units is to take the renewable energy generated by the motor in the process of deceleration into the form of heat to dissipate in the braking resistor for improving the braking performance and shorten the inverter braking time.

it' s need to connect 380V/AC with the R/S terminal for the 4220 and 4300, when external power available, red light(POWER) on |
| working condition of heat elimination fan machine |
braking unit, the fan start work when temperature rise of energy absorption resistor board more than +45C, stop when below +45C. |
