Electric shock due to missing DC link side covers
There is a danger of an electric shock through contact when the side covers of the DC link
are missing.
• Mount the side covers on the first and last component in the drive line-up.
You can order missing side covers (article number: 6SL3162-5AA00-0AA0).
Electric shock due to unsuitable brake cable insulation
When routing brake cables, whose insulation properties are not suitable fo safe electrical
separation, then the insulation can fail resulting in electric shock.
• Connect the holding brake with the specified MOTION-CONNECT cable.
• Only use third-party cables that have brake conductors with insulation properties that
Overheating of the motor cables when the permissible conductor cross-sections are fallen
below
Excessively thin motor cables can result in overheating. This can result in severe injury or
death due to fire and smoke.
• Use cables that correspond to the Motor Module currents. Take into account the routing
• If the rated motor current is less than the rated Motor Module output current, then you
Note
Fault protection when insulation fails in the motor circuit at the output side
In case of insulation failure in the motor circuit, the overcurrent trip meets the requirements
of IEC 60364-4-41:2005/AMD1:2017 - Section 411, Annex D for protection against electric
shock.
• Observe the installation specifications provided in this manual.
• Ensure the continuity of the protective conductor.
• Observe the applicable installation standards.
