Notice:
1. Above selection is based on following condition: 700V DC braking voltage
threshold, 100% braking torque and 10% usage rate.
2. Parallel connection of braking unit is helpful to improve braking capability.
3. Wire between inverter and braking unit should be less than 5m.
4. Wire between braking unit and braking resistor should be less than 10m.
5. Braking unit can be used for braking continuously for 5 minutes. When
braking unit is working, temperature of cabinet will be high, user is not allowed to
touch to prevent from injure.
For more details, please refer to DBU and RBU user manual.
4.5 Wiring the Main Circuits
4.5.1 Wiring at the side of power supply
z
Circuit
breaker
It is necessary to connect a circuit breaker which is compatible with the capacity of
inverter between 3ph AC power supply and power input terminals (R, S, T ). The
capacity of breaker is 1.5~2 times to the rated current of inverter. For details, see
<Specifications of Breaker, Cable, and Contactor>.
z
Contactor
In order to cut off the input power effectively when something is wrong in the system,
contactor should be installed at the input side to control the ON-OFF of the main circuit
power supply.

reactor
In order to prevent the rectifier damage result from the large current, AC reactor should
