All PV module connectors are designed to be easily snapped together, but to require a tool to disconnect the connection once made. The steps for installing an MC4 connector on a wire are as follows:
- Ensure that the connector is the right connector type.
- Ensure that the connector is the right size for the wire.
- Ensure that the connector is the proper polarity for the connection. Positive plastic MC4 connectors (male) insert into negative plastic MC4 connectors (female).
- For each MC4 connector there is a metallic connector that must be crimped onto the wire before it is inserted into the plastic body of the connector. Inside the positive plastic MC4 connector (male) there is a female metallic part. Inside the negative plastic MC4 connector (female) there is a male metallic part.
- Strip back the wire enough to fit into the crimped section of the metallic connector.
- MC4 crimpers have different size crimping dies, select the appropriate size for the wire.
- Crimp the metallic connector around the wire.
- Insert the wire and connector into the plastic body of the correct MC4 connector.
- Tighten the bushing on the back of the connector to ensure that it is water-tight using the plastic MC4 tools.
