power supply has been switched off.
Contact with live parts can result in death or serious injury.
• Wait for 5 minutes before you check that the unit really is in a no voltage condition and
Danger to life caused by high leakage currents when the protective conductor in the line
feeder cable is interrupted
The drive components conduct a high leakage current via the protective conductor.
Touching conductive parts when the protective conductor is interrupted can result in death
or serious injury.
• Carefully comply with the applicable regulations for dimensioning the protective
