Removing any remains of the conductor (only if necessary)
To remove any remains of the conductor (insulation), you can deinstall the locking
mechanism from the terminal module (see Step 3). To do this, the locking
mechanism must be open (upper position). You can only insert the locking
mechanism in the upper position (see Step 4).
1. Insert the screwdriver in the opening below the locking mechanism (the tip of
the screwdriver is on the lip of the locking mechanism).
2. Press the screwdriver downwards to lever the locking mechanism out of the
terminal module.
3. Remove the locking mechanism from the terminal module. Remove any
remains of the conductor from the locking mechanism.
4. Use your fingers to press the locking mechanism back into the opening.
Important: Make sure the locking mechanism is inserted in the correct position,
otherwise you can damage the clamping unit.
