6.7.4 Connecting cables without cable lugs
When appropriately ordered, the terminal clamps can be installed; these clamps are suitable for
finely or multi-stranded conductors without having to use conductor end sleeves. If you wish to
use conductor end sleeves, then correctly crimp these onto the end of the conductor before
connecting up.
NOTICE
Overheating of the conductor ends
If the end of the conductor is not correctly enclosed by the wire end ferrule, but is trapped by
it, this can lead to overheating.
● Insert only one conductor end into each wire end ferrule, and attach the wire end ferrule
correctly.
● Insert only one conductor end into each terminal.
Procedure
When connecting, carefully maintain the minimum clearances as well as the creepage
distances.
1. Open the terminal box and cut the cable to the correct length.
2. Prepare the end of the cable depending on the cable and its use. It is not permissible that
the cable connection is subject to external forces.
3. Insulate the conductor ends in such a way that the remaining insulation reaches almost up
to the terminal clamp.
