How to use
To install the Ergom KO 25/12 terminal, first strip the insulation from the end of the cable to the appropriate length. Insert the conductor into the barrel of the terminal, ensuring all strands are fully contained. Use a professional crimping tool designed for the specific cable size to compress the barrel firmly onto the wire. Once crimped, place the ring over the corresponding stud or bolt and secure it tightly with a nut or screw to ensure optimal electrical contact.
What to consider before purchase
Verify the cable cross-section matches the terminal size
Check the stud diameter of your mounting point
Ensure you have the correct crimping tool for 25 mm² terminals
Assess the environmental conditions of the installation site
Usage recommendations
Always perform a pull test after crimping to ensure the connection is mechanically sound. Ensure the contact surface is clean and free of debris before tightening the bolt to maintain low contact resistance.
