3.1 Montaggio

The Hager SFT140 is designed for modular installation on a DIN rail within an electrical enclosure.

1. Assicurarsi che l'alimentazione principale sia scollegata.
2. Locate an available space on the DIN rail within your electrical panel.
3. Agganciare il bordo superiore dell'interruttore alla guida DIN.
4. Press the bottom of the switch firmly until it clicks into place on the DIN rail.
5. Verify the switch is securely mounted and does not wobble.

3.2 Cablaggio

The SFT140 is a 1-pole changeover switch with common at the top (I-0-II). Refer to the wiring diagram below and the markings on the device for correct connections.

• Terminale 1: Input for Source I
• Terminale 2: Output (Common)
• Terminale 3: Input for Source II
• Terminale 4: Output (Common)

Note: The common connection is typically made at the top terminals (1 and 2) for the output, and the two sources (I and II) are connected to the bottom terminals (3 and 4). However, always verify with the specific markings on your device.

1. Togliere circa 10-12 mm di isolamento dalle estremità dei fili.
2. Loosen the screw terminals on the switch.
3. Insert the wires into the appropriate terminals as per your wiring scheme.
4. Tighten the screw terminals securely. Ensure no bare wire strands are exposed.
5. Controllare attentamente tutti i collegamenti per verificarne la tenuta e la correttezza.

4. Funzionamento

The Hager SFT140 switch has three positions, indicated by the lever:

• Posizione I: Connects the circuit to Source I.
• Posizione 0: Disconnects both Source I and Source II from the circuit (OFF position).
• Posizione II: Connects the circuit to Source II.

To change the position, simply move the operating lever to the desired setting (I, 0, or II). Ensure the lever is fully engaged in each position.

5. Manutenzione

The Hager SFT140 Modular Changeover Switch is designed for maintenance-free operation under normal conditions.

• Periodically inspect the device for any signs of physical damage, overheating (discoloration), or loose connections.
• Ensure the operating lever moves freely and engages positively in all three positions.
• Clean the exterior of the switch with a dry, soft cloth if necessary. Do not use abrasive cleaners or solvents.
• If any issues are observed, disconnect power immediately and consult a qualified electrician.
