How to use

To use the Wago 280-903, mount the terminal block onto a standard DIN-rail until it clicks into place. Strip the insulation from your wire to the recommended length and insert the conductor into the terminal opening. Ensure the wire is fully seated to guarantee a secure electrical contact. For multi-wire configurations, follow standard wiring diagrams to ensure correct circuit routing.

What to consider before purchase

• Verify that the 2.5mm2 wire size is compatible with your specific project requirements.
• Ensure you have the correct DIN-rail type for mounting.
• Check if the red color coding aligns with your internal wiring standards or phase identification requirements.

Usage recommendations

Always ensure that the power supply is disconnected before performing any wiring work. Use appropriate wire stripping tools to prevent damage to the conductor strands and ensure a reliable connection.
