Using an MC4 ST Crimping Tool
- Prepare the Cable:
- Strip the Insulation: Use a coaxial cable stripper or wire stripper to remove the insulation from the solar cable. Follow the specifications for the correct length of stripped wire.
- Assemble the Connector:
- Insert the Cable: Place the stripped wire into the MC4 connector, ensuring the wire is properly positioned within the connector.
- Crimp the Connector:
- Align the Tool: Position the MC4 connector in the crimping tool, aligning it with the correct die for the connector size.
- Crimp: Squeeze the handles firmly to crimp the connector onto the cable. Ensure the crimp is secure and the connection is reliable.
- Inspect the Connection:
- Check Fit: Ensure that the connector is properly crimped and the wire is securely terminated.
- Test the Connection: If possible, perform a continuity test to verify the connection’s reliability.
