Tips

When soldering these terminal blocks to a PCB, ensure the board is clean and use a soldering iron with appropriate temperature control. Strip wires to the specified length of 5 mm for optimal contact. For stranded wires, consider tinning the ends or using ferrules to prevent fraying. Tighten screws firmly but avoid over-tightening to prevent damage to the wire or terminal.
