1. The input EMI meet the requirement of C3 after adding input filters.
2. Above options are external, the customer should indicate when purchasing.
C.8 Braking system
C.8.1 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 avoid this accident happens.
 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 property 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 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 resistors with the inverter according to the diagram.
Incorrect wiring may cause damage to the inverter or other devices.
