   • Important: Observe correct polarity for DC coils. A warning label on the device indicates "Please confirm polarity before using!".
3. Wiring the Main Circuit (Load):
   • Connect the AC load circuit to the main power terminals (e.g., 1, 3 for input and 2, 4 for output).
   • Ensure all connections are tight and secure to prevent loose contacts and overheating.
   • Verify that the main circuit voltage and current do not exceed the contactor's ratings (e.g., 25A, 250V/500V).
4. Final Check: Before applying power, double-check all wiring for correctness and security.

5. Operating Instructions

The TOCT1-25Z modular contactor operates by energizing its DC coil, which then closes or opens the main AC contacts to control the connected load.

• Activation: When the specified DC control voltage (12V or 24V) is applied to the coil terminals, the contactor will activate, changing the state of its main contacts (e.g., 2NO contacts will close, 1NO 1NC will have NO close and NC open).
• Deactivation: Removing the control voltage from the coil terminals will deactivate the contactor, returning the main contacts to their original state.
• Status Indication: The contactor features a disconnection display, where an indicator light provides clear visual feedback on its operational status (open or closed).

6. Maintenance

The TOCT1-25Z modular contactor is designed for long-term, reliable operation with minimal maintenance. However, periodic checks are recommended:

• Visual Inspection: Regularly inspect the contactor for any signs of physical damage, discoloration, or loose connections.
• Terminal Tightness: Periodically check that all wiring terminals are securely tightened. Loose connections can lead to overheating and device failure.
• Cleaning: If necessary, gently clean the exterior of the contactor with a dry, soft cloth. Do not use solvents or abrasive cleaners.
• Environmental Conditions: Ensure the operating environment remains within the specified temperature and humidity ranges to prevent premature wear.

CAUTION: Always disconnect power to the circuit before performing any inspection or maintenance.

7. Troubleshooting

If the contactor is not functioning as expected, consider the following common issues and solutions:
