Lignes directrices pour l'installation par des professionnels

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

1. Veiller à ce que la surface de montage soit robuste, résistante à la chaleur et offre un espace suffisant pour la dissipation de la chaleur.
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. Desserrer complètement les vis des bornes avant d'insérer les fils pour éviter d'endommager les conducteurs.
6. Insérer complètement le fil dans l'ouverture de la borne, en veillant à ce qu'aucun conducteur exposé ne dépasse du boîtier en céramique.
7. Tighten M5 screws progressively to a final torque of 1.8-2.2 N·m
8. Vérifier l'intégrité de la connexion par une inspection visuelle et un essai d'arrachement mécanique.
9. Maintain appropriate clearance between adjacent high-current terminal blocks for heat dissipation
10. Mettre en place un programme d'entretien régulier pour l'inspection et le resserrage des connexions à haute intensité.
