Tips

For reliable push-in connections, ensure conductor ends are clean and, for flexible wires, use ferrules. The blue housing is ideal for marking neutral conductors in accordance with wiring conventions. Always verify that the DIN rail is properly grounded and that the terminal block is securely snapped onto the rail.
