6.3.3 Cable ends with wire end sleeves
1. Preferably use end sleeves instead of soldering cable ends.
2. Before connecting, attach the end sleeves so as to form a technically correct, current-
carrying crimped joint at the end of the conductor.
WARNING
Risk of explosion due to excessive temperature rise
If the end of the conductor is not correctly enclosed by the end sleeve, but is trapped by
it, this can lead to overheating. The temperature class of the machine can be exceeded.
This can trigger ignition of an explosive mixture. This can result in death, serious injury or
material damage.
● Insert only one conductor end into each end sleeve. Attach the end sleeve correctly.
