5.2 Parentah Wiring

Refer to the wiring diagram below for proper connection of power sources and load. Ensure all connections are made with appropriate wire gauges and are tightened to the specified torque.

Gambar 5.2: Detailed wiring diagram for the ATS. Connect "Common power input" (Source A) and "Backup power input" (Source B) to their respective terminals. "Load output" connects to the downstream electrical panel. "Common control lines" and "Backup control line" are for automatic switching logic.

• Source A (Common Power Input): Connect the primary power source (e.g., utility grid) to the terminals labeled "Source A". Ensure correct phase (R, S, T) and neutral (N) connections.
• Source B (Backup Power Input): Connect the secondary power source (e.g., generator) to the terminals labeled "Source B". Ensure correct phase (R, S, T) and neutral (N) connections.
• Kaluaran Beban: Connect the load (e.g., electrical panel for critical circuits) to the terminals labeled "Load Side".
• Kontrol kabel: Connect the control lines as indicated in the diagram. These lines are crucial for the automatic detection and switching logic.
• Grounding: Ensure proper grounding for both power sources and the ATS unit.

After all connections are made, double-check wiring for correctness and tightness before restoring power.

6. Parentah Operasi

The ATS offers both automatic and manual operation modes. The selection is made via the red rotary switch on the front panel.

6.1 Automatic Mode (Auto)

In "Auto" mode, the ATS will automatically detect the presence and quality of power from Source A (primary) and Source B (backup) and switch the load accordingly.

1. Set the rotary switch to the "Auto" position.
2. When Source A is present and stable, the ATS will connect the load to Source A.
3. If Source A fails or becomes unstable, the ATS will automatically transfer the load to Source B (if Source B is present and stable) after a pre-set delay.
4. When Source A is restored and stable, the ATS will automatically transfer the load back to Source A after a pre-set delay.

Catetan: The specific transfer delays are factory set or configurable depending on the model. Refer to the product label for details.

6.2 Manual Mode (Manual)

In "Manual" mode, the user can manually select the desired power source using the red handle.

1. Set the rotary switch to the "Manual" position.
2. To switch to Source A, rotate the red handle to the "A" position.
3. To switch to Source B, rotate the red handle to the "B" position.
4. To place the switch in a neutral or off position (disconnecting both sources), rotate the handle to the center position.

Awas: When operating in manual mode, ensure that the selected power source is stable and safe to connect to the load. Avoid switching under heavy load conditions if possible.

7. Pangropéa

Regular maintenance ensures the longevity and reliable operation of your ATS. Always disconnect power before performing any maintenance.

• Inspeksi périodik: Annually inspect the ATS for any signs of physical damage, discoloration, or loose connections.
• Kakuatan Terminal: Periodically check and re-tighten all terminal screws to ensure good electrical contact.
• beberesih: Keep the ATS free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners or solvents.
• Uji Fungsional: Periodically test the automatic transfer function by simulating a primary power failure (if safe to do so and with proper precautions).
