Output filter filter can reduce the RFI noise caused by the cables between the inverter and the motor and the
leakage current of the conducting cables.
C3 Filter
Note:
1. The Inverter meets category C3 at 3 Mtrs when fitted with above filter.
2. The C3 filters are external mounted option.
C2 Filter
Note:
1. The Inverter meets category C2 at 5 Mtrs when fitted with above filter.
2. The C2 filters are external mounted option.
C.7 braking system
C.7.1 Select the braking components
The motor will become a generator if its actual rotating speed is higher than the corresponding speed of the
reference frequency. As a result, the inertial energy of the motor and load return to the inverter to charge the
capacitors in the main DC circuit. When the voltage increases to the limit, damage may occur to the inverter. It is
necessary to apply braking resistor to prevent inverter damage and control stopping of motor.
Only qualified electricians are allowed to design, install, commission and operate on the
inverter.
Follow the instructions in “warning” during working. Physical injury or death or serious
damage may occur.
Only qualified electricians are allowed to wire. Damage to the inverter or braking options
and part may occur. Read carefully the instructions of braking resistors or units before
