11.2 Safety instructions for control panel manufacturing
Electric shock caused by high leakage currents when the protective conductor in the line
feeder cable is interrupted
Drive components conduct high discharge currents 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 when dimensioning the protective
Electric shock due to incorrectly routed brake cables
When routing brake cables without safe electrical separation, the insulation can fail
resulting in electric shock.
• Connect the holding brake using the MOTION-CONNECT cable intended for the
• Only use third-party cables that have brake cores with safe electrical separation or
Fire due to overheating resulting from excessively long connecting cables
Excessively long power cables can cause overheating of components with resulting fire and
smoke development.
• The cable lengths (e.g. motor cable, DC-link cable) listed in the technical data must not
Danger of injury caused by foreign objects in the device
Parts (e.g. drilling chips, end sleeves) falling into the device can cause short-circuits and
damage the insulation. This can lead to serious injuries (arcing, bang, pieces flying out of
the equipment).
• Only perform installation and other work when the devices are current-free.
• Cover the ventilation slits during the installation of the cabinet and remove the cover
