Danger to life if the fundamental safety instructions and residual risks are not heeded
Not observing fundamental safety instructions and residual risks stated in Chapter 1 can
result in accidents with severe injuries or death.
• Follow the fundamental safety instructions.
• Consider the residual risks on the risk assessment.
Danger to life caused by high leakage currents when the protective conductor in the line
feeder cable is interrupted
Drive components conduct high leakage currents through the PE conductor. When the PE
conductor is interrupted, touching live components can result in electric shock, which can
lead to death or serious injuries.
• Carefully comply with the applicable regulations when dimensioning the protective
Danger to life as a result of electric shock for 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 hazard due to overheating when permissible cable lengths are exceeded
Excessively long power cables can cause overheating of components with resulting fire and
smoke development.
