4. Electrical Connection:
   • Ensure the main power supply is disconnected before making any electrical connections.
   • Connect the fan's 3-wire cable to a compatible AC220V power source. Refer to local electrical codes for proper wiring. Typically, these wires are Live, Neutral, and Ground. If unsure, consult a qualified electrician.
   • Verify all connections are secure and insulated to prevent short circuits.
5. Pre-Operation Check: Before restoring power, double-check all connections and ensure there are no obstructions around the fan blades.

7. Operation

The YNF300-2T axial fan is designed for continuous operation once properly installed and connected to power.

1. Power On: Restore power to the fan's circuit. The fan should begin operating immediately.
2. Monitoring: Observe the fan during its initial operation for any unusual noises, vibrations, or signs of malfunction.
