3. Informació de seguretat
WARNING: Risk of electric shock or explosion.
- La instal·lació, l'ajust, la reparació i el manteniment només els ha de dur a terme personal qualificat.
- Desconnecteu tota l'alimentació abans de treballar en l'equip.
- Utilitzeu sempre un volum de classificació adequadatage sensing devices to confirm power is off.
- Utilitzeu només el volum especificattage for the control coil.
- Assegureu-vos de connectar a terra i cablejar correctament d'acord amb els codis elèctrics locals i nacionals.
- El no seguir aquestes instruccions pot provocar la mort, lesions greus o danys a l'equip.
4. Configuració i instal·lació
The LC1D12EHE contactor can be mounted on a DIN rail or directly to a panel using screws.
4.1. Muntatge
Muntatge en carril DIN:
- Assegureu-vos que el carril DIN estigui ben fixat dins de la carcassa.
- Enganxeu la vora superior del contactor al carril DIN.
- Press the bottom of the contactor firmly until it clicks into place.
Muntatge al panell:
- Identify the mounting holes on the contactor base.
- Mark and drill appropriate holes on the panel surface.
- Secure the contactor using screws of suitable size and length.
4.2. Cablatge
Refer to the wiring diagram provided with your specific application or system. The contactor features screw clamp terminals for both power and auxiliary connections.
- Power Terminals (1L1, 3L2, 5L3, 2T1, 4T2, 6T3): Connect the main power circuit to these terminals. Ensure correct phase sequence for 3-phase applications.
- Control Coil Terminals (A1, A2): Connect the 48-130VAC/VDC control voltage a aquests terminals.
- Auxiliary Contacts (13 NO, 14 NO, 21 NC, 22 NC): Use these contacts for control circuit interlocking, signaling, or other auxiliary functions.
Always verify all connections are tight and secure before applying power.

5. Funcionament
The TeSys Deca Green contactor is designed for switching electrical loads, primarily motors, in industrial control applications. When the appropriate control voltage (48-130VAC/VDC) is applied to the coil terminals (A1 and A2), the contactor's main contacts close, allowing power to flow to the connected load.
- Energitzant la bobina: Applying the specified voltage to A1 and A2 will energize the coil, causing the main power contacts (1L1-2T1, 3L2-4T2, 5L3-6T3) to close. Simultaneously, the built-in auxiliary contacts will change state (NO contacts close, NC contacts open).
- Desactivació de l'alimentació de la bobina: Eliminació del voltage from A1 and A2 will de-energize the coil, causing the main power contacts to open and the auxiliary contacts to return to their original state.
Ensure the control circuit is properly designed and protected to prevent unintended operation or damage.
6. Manteniment
Regular inspection and maintenance are crucial for ensuring the long-term reliability and safe operation of the contactor.
- Desconnexió d'alimentació: Always disconnect all power to the contactor and associated circuits before performing any maintenance.
- Inspecció visual: Inspeccioneu periòdicament el contactor per detectar signes de desgast, danys, decoloració o connexions soltes. Comproveu si hi ha acumulació de pols o restes.
- Estanquitat del terminal: Verify that all screw clamp terminals are securely tightened. Loose connections can lead to overheating and component failure.
- Contact Condition: While the contactor is de-energized, visually inspect the main contacts for excessive pitting or erosion. Severely worn contacts may require replacement of the contactor.
- Neteja: Use a dry, lint-free cloth to clean the exterior of the contactor. Do not use solvents or abrasive cleaners.
Do not attempt to repair internal components. If the contactor is damaged or malfunctioning, replace the unit.
