6.5.6
Connecting cables without cable lugs
Lug terminal connections - which are suitable for connecting flexible and stranded conductors
without the use of wire end ferrules - may be installed if ordered accordingly. 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 and creepage distances.
1. Open the terminal box and cut the cable to the correct length.
The clips of the 1XB7730/1XB7731 terminal boxes can accept cables with maximum
185 mm² cross-section.
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 cable lug.
