Installation Instructions

1.Wire Preparation: Strip insulation from the wire end to match the terminal length, ensuring no strands are cut or damaged.

2.Insertion: Fully insert the stripped wire into the terminal until it reaches the end of the barrel.

3.Crimping: Use a high-quality, size-matched crimping tool to apply uniform pressure to the terminal barrel.

4.Inspection: Gently pull the wire to verify the connection is secure with no slippage or movement.

5.Insulation: Cover the crimped joint with heat-shrink tubing or electrical tape to protect against moisture, corrosion, and short circuits.
