4. Configuració i instal·lació

Follow these steps for proper installation of the LW205 Terminal Enlargement:

1. Desconnexió d'alimentació: Ensure that the main power supply to the contactor and associated circuitry is completely disconnected and secured against accidental re-energization.
2. Contactor Preparation: Identify the designated mounting points on the AF190 or AF205 contactor for the terminal enlargement. Refer to the contactor's specific manual for detailed diagrams.
3. Mounting the LW205: Align the LW205 Terminal Enlargement with the contactor's terminals. Secure it firmly using the provided hardware (if applicable) or by engaging its designed interlocking mechanism. Ensure a snug fit to prevent movement or loose connections.
4. Connexions de cablejat: Connect the appropriate conductors to the enlarged terminals. Ensure that all connections are clean, properly stripped, and tightened to the manufacturer's specified torque values to prevent overheating and ensure optimal electrical contact.
5. Verificació: Visually inspect all connections for proper seating and tightness. Confirm that no bare wires are exposed and that there are no potential short circuits.
6. Restauració d'energia: Un cop finalitzada i verificada la instal·lació, restableix l'alimentació del sistema.

5. Ús i funcionalitat

The LW205 Terminal Enlargement functions as a passive component that expands the connection capabilities of the AF190 and AF205 contactors. Once installed, it allows for:

• Connection of larger gauge wires than the standard contactor terminals might accommodate.
• Increased flexibility in wiring configurations.
• Improved current carrying capacity at the connection points due to larger contact areas.

No operational adjustments are required for the terminal enlargement itself; its function is integrated with the contactor's operation.

6. Manteniment

Regular maintenance helps ensure the longevity and reliable performance of the LW205 Terminal Enlargement:

• Inspecció periòdica: Annually, or more frequently in harsh environments, inspect the terminal enlargement for any signs of physical damage, discoloration (indicating overheating), or loose connections.
• Neteja: With power disconnected, gently clean any dust or debris from the terminals and surrounding areas using a dry, non-conductive brush or compressed air. Avoid using liquids.
• Comprovació d'estanquitat: Periodically re-check the torque of all terminal connections to ensure they remain secure.
• Condicions ambientals: Assegureu-vos que l'entorn operatiu es mantingui dins dels rangs de temperatura i humitat especificats per evitar una degradació prematura.

7. Solució De Problemes

The LW205 Terminal Enlargement is a passive component, so most issues will relate to its installation or the overall electrical system. Consider the following if problems arise:

• Overheating at Terminals: This often indicates a loose connection or insufficient wire gauge for the current. Disconnect power, inspect and re-tighten all connections, and verify wire sizing.
• Connexió intermitent: Check for loose mounting of the terminal enlargement to the contactor, or loose wire connections.
• Danys físics: If the terminal enlargement is physically damaged (cracked, broken), it must be replaced immediately to ensure safety and proper function.

For issues related to the contactor itself, refer to the ABB AF190/AF205 contactor instruction manual.
