To install the APsystems 2300532 25A AC Connector EN 3-Wire, follow these steps:
Step 1: Verify the AC connector type. Make sure you have the correct connector, either the 25A AC Male Connector (EN,3-wire) or the 25A AC Female Connector (EN,3-wire).
Step 2: Prepare the wires. Strip the insulation from the wires using a wire stripper. The recommended wire gauge is 3x2.5mm²~4mm² (or 14AWG~12AWG), and the cable outer diameter should be between 10mm and 12mm. The earth wire should be longer than the live and neutral wires.
Step 3: Install the AC connectors. Set the parts on the cable in the order of 1→2→3→4. Crimp the wires according to the printed markings on the plastic core of the connector. Use a xxxx twisting torque of 0.8 +/_0.1N.m. Push the housing into the body until you hear a click sound. Insert the seal and clamp finger into the body, then tighten the nut to the specified torque.
Note: The installation process for the cable end female connector is the same as the male connector.
