 IV. Operation and Maintenance Suggestions

1. **Installation Key Points**

   - **Ambient Temperature**: -10°C to +40°C (without derating), and forced air cooling is required when it exceeds 40°C.

   - **Wiring Specifications**: Shielded wires should be used for input and output cables, and the grounding resistance should be ≤10Ω.

   - **Harmonic Governance**: It is recommended to install an input reactor (optional) to reduce interference with the power grid.

2. **Maintenance Cycle**

   - **Daily Inspection**: Clean the dust on the radiator every month and check whether the wiring terminals are loose.

   - **Regular Maintenance**: Replace the cooling fan every six months and detect the capacity of the electrolytic capacitor every year.

   - **Fault Handling**: Common fault codes (such as OC overcurrent, OV overvoltage) can be troubleshot through the user manual, and serious problems need to be returned to the factory for repair.
