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 unit/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

Connect the braking resistor or braking unit with the inverter according to the
diagram. Incorrect wiring may cause damage to the inverter or other devices.
