Step 1. Quarter-turn the Catenary Fixing on to the Catenary Wire. Compress the CAMs to position it horizontally before releasing them to lock the position in place.
Step 2. Place the Contact Clamp on to the anvil of the Contact wire.
Step 3. Flip the lever to lock it into place. Ensure the hooks are fully over the clamp.
Step 4. Push the Catenary Fixing's release button and pull through to the desired height.
Step 5. Wrap any excess wire which is above the Catenary Fixing over the other side of the product and push it through the lower hole to create a fail safe.
