6. Installation Instructions

1. Pre-Installation: Power off motor/drive; lockout/tagout; ensure motor rear face is clean

2. Mount Bracket: Align bracket to motor rear mounting holes; tighten screws to 2.5–3.0 Nm

3. Attach Fan: Secure fan assembly to bracket; ensure free rotation (no rubbing)

4. Install Cover: Fit mesh cover to fan; fasten with provided screws

5. Electrical Connection:

   • Connect fan cable to 200–240 VAC (L, N, PE)

   • Ground fan housing to motor ground

   • Route cable to avoid moving parts and heat sources

6. Commissioning: Power on; verify fan rotation (correct airflow toward motor); check for noise/vibration

7. Maintenance

• Monthly: Inspect fan blades/cover for dust/debris; clean with dry brush or compressed air (≤ 0.5 MPa)

• Quarterly: Check mounting screw torque; verify cable insulation and connections

• Bearing Life: No lubrication required; replace fan if noise increases or speed drops

• Environment: Keep ambient temp ≤ 40°C; avoid oil mist, corrosive gases, and heavy dust

8. Troubleshooting

• Fan Not Running: Check 200–240 VAC supply; verify wiring/grounding; check internal thermal fuse

• Abnormal Noise: Clean blades/cover; check for loose screws or bearing wear

• Low Airflow: Clear blockages; verify correct rotation direction

• Overheating Trip: Reduce ambient temp; ensure adequate ventilation; check for motor overload

9. Safety Precautions

• Install/service only by qualified electrical/mechanical personnel

• Disconnect power before maintenance; wait 5 minutes for discharge

• Do not operate without fan cover; risk of rotating-part injury

• Keep fingers/tools clear of rotating fan during operation

• Ensure proper grounding to prevent electric shock
