VII. Spécifications d'installation et de câblage

Étapes d'installation:

Confirm that the installation environment meets the range of -25℃~+55℃, free from severe vibration and corrosive gases.
Select a 35mm standard DIN rail and ensure the mounting surface is flat.
Align the contactor’s snap with the rail, press down and slide to fix (one-hand operation).
Cut off all power supplies before wiring, and use a multimeter to confirm no voltage exists.
Main circuit wiring: L1/L2/L3 → input terminals, T1/T2/T3 → output terminals.
Control circuit wiring: A1/A2 → coil power supply, 13/14 → normally open auxiliary contacts, 21/22 → normally closed auxiliary contacts.
Une fois le câblage terminé, gently pull the wires to confirm they are connected firmly without loosening.

Terminal Block Specifications:

Circuit principal: M6 bolts, suitable for copper core wires with cross-sectional area of 1.5-16mm²

Circuit de commande: M3.5 bolts, suitable for copper core wires with cross-sectional area of 0.5-2.5mm²

Guide de dépannage

Phénomène de défaut	Causes possibles	Solutions
Le contacteur ne parvient pas à s'enclencher	No voltage/low voltage on coil; Grillage de la bobine; Bourrage mécanique	Check the control circuit; Mesurer la résistance de la bobine (approximately several hundred ohms under normal condition); Clean foreign objects and lubricate moving parts
Excessive noise after pull-in	Faible tension de bobine; Oil stain/rust on iron core end face; Anneau de court-circuit cassé	Adjust control voltage to rated value; Clean iron core end face; Replace coil assembly
Surchauffe/ablation des contacts	Load overload; Mauvais contact des contacts; Câblage lâche	Vérifier le courant de charge; Polish contacts or replace them; Re-tighten terminal blocks
Auxiliary contact failure	Usure des contacts; Erreur de câblage	Replace auxiliary contact module; Check wiring polarity

Safety and Maintenance Precautions
Fonctionnement hors tension: Cut off all power supplies before installation and maintenance, and hang the “Pas de mise sous tension” signe.
Inspection régulière: Conduct inspection every 6 mois, including contact wear, terminal tightness and coil temperature.
Contact Replacement: Replace the main contacts in time when the wear amount exceeds 1mm or the surface is severely ablated.
Exigences environnementales: Avoid use in humid and dusty environments; install a protective housing if necessary.
Accessoires compatibles: Only use auxiliary contacts, interlock devices and other accessories original or certified by ABB to ensure safety performance.
