Linee guida per l'installazione professionale

For optimal performance, safety, and compliance with electrical codes in high-current multi-circuit applications, follow these specialized installation guidelines:

1. Ensure the mounting surface is robust, heat-resistant, and provides adequate space for heat dissipation
2. Utilize the integrated 17mm mounting holes for secure attachment to industrial panels
3. Strip wires to the appropriate length (typically 10-12mm for larger gauge conductors)
4. For stranded conductors, use ferrules or pre-twist for optimal connection integrity
5. Fully loosen terminal screws before inserting wires to prevent conductor damage
6. Inserire completamente il filo nell'apertura del terminale, assicurandosi che nessun conduttore esposto fuoriesca dall'alloggiamento in ceramica.
7. Tighten M5 screws progressively to a final torque of 1.8-2.2 N·m
8. Verify connection integrity through both visual inspection and a mechanical pull test
9. Maintain appropriate clearance between adjacent high-current terminal blocks for heat dissipation
10. Implement a regular maintenance schedule for inspection and re-torquing of high-current connections
