wiring, function parameter setting, routine maintenance, troubleshooting and troubleshooting
of the inverter.
In order to fully utilize the functions of the product and ensure the safety of users and
equipment, please read this manual carefully before using the inverter. Improper use may
cause the inverter to operate abnormally, malfunction, reduce the service life, and even
cause equipment damage, personal injury and other accidents!
Please pay special attention to the following safety precautions when handling this
product.
Please ensure to turn off the power when wiring.
The inverter must be properly grounded.
The AC power cord must never be connected to the inverter output terminals
U, V, W.
There is a high voltage circuit inside the inverter. It is strictly forbidden to
touch the internal parts by hand.
Only qualified electricians can install, wire, repair and repair the inverter.
Install the inverter in a suitable environment to prevent direct exposure to
high temperatures and sunlight, and to avoid splashing of moisture and water
droplets.
Please perform at least five minutes after the power is turned off during
inspection and maintenance.
Never modify the parts or circuits inside the inverter by yourself.
Do not test the voltage inside the inverter.
This series of products cannot be used in situations that endanger personal
safety.

  • Page 158 Chapter 9 Appendix Appendix B Brake resistor selection During the running process of the inverter, if the speed of the controlled motor drops too fast, or the motor load shakes too fast, its electromotive force will reverse the internal capacitance of the inverter through the inverter, so that the voltage across the power module is pumped up, which is easy.
