This preventive maintenance manual provides safety guidelines, inspection checklists, and detailed procedures for maintaining the ABB ACS800-67 wind power…
The manual outlines safety requirements, the importance of regular maintenance, and a comprehensive checklist for preventive upkeep of the ACS800-67 wind power converter. It covers inspection of circuit breakers, cabinet components, LCL filters, contactors, and UPS systems.
Detailed step‑by‑step procedures are provided for tasks such as cleaning and lubricating moving parts, replacing air filters, checking capacitor values, and verifying sensor settings. Appendices include additional checklists and protection setting tables. This manual is written in Chinese.
| LCL filter capacitor minimum capacitance | >75 µF |
|---|---|
| Fan capacitor minimum capacitance | >3.6 µF |
| M12 bolt torque | 70 Nm |
| Temperature sensor set points | E2 10 °C, E3 55 °C |
| Humidity sensor set point | 80 % |
| Encoder shield exposed length | <5 cm |
Only qualified electrical engineers are allowed to maintain and inspect the converter.
The stator and ACS800-67 power must be disconnected and the rotor locked with a mechanical brake.
A torque of 70 Nm should be applied to M12 bolts.
