5. Persediaan dan Pemasangan

5.1 Langkah Keselamatan

• Ensure power is disconnected before any installation or maintenance.
• Pemasangan hendaklah dilakukan oleh kakitangan yang berkelayakan sahaja.
• Pakai peralatan perlindungan diri (PPE) yang sesuai.
• Sahkan bahawa bekalan voltage and frequency match the motor's specifications.
• Pastikan motor dibumikan dengan betul.

5.2 Pemasangan

The motor is designed for horizontal foot mounting (B3). Use the pre-drilled holes on the fixed base for secure installation. Ensure the mounting surface is stable, level, and capable of supporting the motor's weight (15kg) and operational forces.

Refer to the dimensions in Section 4.1 for precise mounting hole spacing.

5.3 Sambungan Elektrik

The motor requires a 3-phase power supply. The default connection for nominal output ≤4hp (3kW) is a Star (Y) connection for 380V. For 220V operation, you may need to change to a Delta (Δ) connection. Consult a qualified electrician for wiring.

Wiring must comply with local electrical codes and regulations.

This image provides standard wiring diagrams for three-phase squirrel-cage induction motors, including Star (Y), Delta (Δ), and Star-Delta (Y-Δ) connections, as well as configurations for two-speed motors.

• Star (Y) Connection: Typically used for higher voltage (e.g., 380V). Connect terminals W2, U2, V2 together, and connect L1, L2, L3 to U1, V1, W1 respectively.
• Delta (Δ) Connection: Typically used for lower voltage (e.g., 220V). Connect U1-W2, V1-U2, W1-V2, then connect L1, L2, L3 to these respective junctions.
• Pembumian: Always connect the motor's ground terminal to a reliable earth ground.

6. Arahan Operasi

6.1 Pemeriksaan Pra Operasi

• Confirm all electrical connections are secure and correct.
• Ensure the motor is properly mounted and aligned with the driven equipment.
• Check for any obstructions around the motor's cooling fan and ventilation holes.
• Verify that the ambient temperature is within the specified range (-15°C to +40°C).

6.2 Memulakan Motor

1. Apply power to the motor circuit.
2. Observe the motor for any unusual noises, vibrations, or overheating during the initial startup.
3. If any abnormalities are detected, immediately shut off power and investigate the cause.

6.3 Menghentikan Motor

To stop the motor, simply disconnect the power supply to the motor circuit.

7. Penyelenggaraan

Regular maintenance is crucial for ensuring the longevity and optimal performance of your ATO AC Induction Motor. Always disconnect power before performing any maintenance.

7.1 Routine Checks (Monthly)

• Pemeriksaan Visual: Check for any signs of physical damage, corrosion, or loose connections.
• Kebersihan: Ensure the motor's cooling fins and ventilation openings are free from dust, dirt, and debris to maintain efficient heat dissipation.
• Bunyi dan Getaran: Listen for any unusual noises or feel for excessive vibrations during operation.
• Suhu: Monitor the motor's operating temperature. Excessive heat can indicate a problem.
