5. Persediaan dan Pemasangan
PENTING: Installation must be performed by a qualified electrician or technician familiar with industrial electrical systems and safety procedures.
- Pemutusan Kuasa: Before beginning installation, ensure that the main power supply to the equipment where the fan will be installed is completely disconnected and locked out.
- Pemasangan: Securely mount the axial fan to the designated cooling position on the spindle motor or equipment. Ensure that the mounting surface is stable and can support the fan's weight and operational vibrations. Use appropriate fasteners.
- Pendawaian:
- Identify the fan's 4-pin power connector and the corresponding power input on your equipment.
- Connect the fan's wires according to the wiring diagram provided with your equipment or the fan's specific wiring instructions (if separate documentation is available). Pay close attention to phase connections (3-phase) and voltage requirements (AC 230V or 400V).
- Ensure all connections are tight and insulated to prevent short circuits or electrical hazards.
- Properly ground the fan as per local electrical codes.
- Arah Aliran Udara: Verify that the fan is oriented to provide the correct airflow direction for optimal motor cooling. Axial fans typically draw air from one side and expel it from the other.
- Pembersihan: Ensure there is adequate clearance around the fan for unobstructed airflow and to prevent contact with moving parts or other components.
- Semakan Akhir: After installation, visually inspect all connections and mounting points.
