How to use

To install the Wago 788-508, snap the relay onto a standard DIN-rail within your control cabinet. Ensure that the power supply is disconnected before wiring the input and output terminals. Connect the 230V AC control signal to the coil terminals and the load circuit to the switching contacts, ensuring that the current does not exceed the specified 16A limit. Once wired, verify all connections for tightness and perform a functional test before energizing the system.

What to consider before purchase

• Verify that your control system voltage matches the 230V AC requirement.
• Ensure the load current does not exceed 16A.
• Confirm that your cabinet has sufficient DIN-rail space for a 15 mm wide module.
• Check environmental conditions to ensure they are within standard industrial operating ranges.

Usage recommendations

Always ensure that the relay is installed by a qualified professional in accordance with local electrical regulations. Regularly inspect the contacts and terminal connections during scheduled maintenance to ensure optimal performance and safety.
