8. Troubleshooting the inverter
Prior to operating all electronic parts, the following aspects should be taken into consideration first
Note: Onlyeligible and qualified personnel can make electronic adjustments.
1. Disconnect machine from power supply.
2. Electronic parts are extremelysensitive, do not use hands or metal tools to remove or install such parts.
3. As remaining voltage still exists in the capacitor even after the electric current has been cut off, wait until the light disappears
from the lighted displaycompletelybefore proceeding with any work to prevent any accidents or hazards from occurring.
4. Pay close attention to the electronic circuit board so that they are free from any defects.
5. Never connect the alternating current directly to the output connector (U/V/W) of the speed adjuster. The electronic self-
diagnosis program can notifyyou of situations like motor overloading and too low or too high voltage, etc. When the program
detects an error, the machine will stop immediately and such error will be displayed on the inverter’s digital display. Follow
the solutions to correct any errors. Close the electrical cabinet and connect machine to power supply.
