To use the relay, insert it into a compatible socket designed for 2 mm flat plug connections. Ensure the coil voltage matches your control signal of 12V DC. Once installed, the relay can be operated automatically via the control circuit or manually using the integrated test button for testing purposes. Always ensure the power is disconnected before performing any wiring or maintenance tasks on the socket.

What to consider before purchase

• Verify that your control system provides a stable 12V DC supply.
• Ensure the load current does not exceed the 7A limit.
• Check that the socket used is compatible with the 2 mm flat plug terminal layout.
• Confirm the environmental conditions are within the specified temperature range.

Usage recommendations: Regularly inspect the relay for signs of wear or contact degradation, especially in high-frequency switching applications. Use the test button periodically to ensure the mechanical parts remain functional and the contacts are clean.
