Installation & Maintenance Recommendations
Installation Notes
- Mounting: Secure the drive to a wall or base using shock-absorbing pads to reduce vibration transmission and ensure stable operation.
- Cooling Space: Leave sufficient clearance (approximately 75mm) around the drive for smooth ventilation, and keep the air outlet unobstructed at all times.
- Cable Routing: Separate power cables from control cables; route output power cables and input control cables apart to avoid electromagnetic interference.
- Grounding: Follow the instruction manual strictly for proper grounding to prevent static buildup and ensure operational safety.
Maintenance Tips
- Regular Inspections: Check the tightness of power cables and connection terminals at least once a year to avoid loose connections and potential failures.
- Fan Cleaning: Remove dust from fan blades and cooling vents regularly to keep the cooling system efficient and prevent overheating faults.
- Troubleshooting: Refer to the instruction manual and use the fault codes displayed on the keypad (such as E1, E2) for quick fault diagnosis and resolution.
