Danger to life through electric shock when the protective cover of the DC link is open
Contact with live parts can result in death or serious injury.
• Only operate the components with closed protective cover.
Danger to life due to high leakage currents caused by an interrupted external protective
conductor
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.
• Ensure that the external protective conductor satisfies at least one of the following
conditions:
– It has been laid so that it is protected against mechanical damage.
1)
– If it is a single conductor, it has a cross-section of at least 10 mm² Cu.
– If it is a conductor of a multi-conductor cable, it has a cross-section of at least 2.5
mm² Cu.
– It has a second protective conductor in parallel with the same cross-section.
– It complies with the local regulations for equipment with increased leakage current.
1)
Cables laid within control cabinets or closed machine housings are considered to be
1)
adequately protected against mechanical damage.
Danger to life through electric shock due to incorrect connection to the DC link
Incorrect connections can lead to overheating and therefore a risk of fire. There is also a
risk of an electric shock. This can result in serious injury or death.
• Only use adapters (DC link adapters and DC link rectifier adapters) released by
Siemens for the connection to the DC link.
Danger to life through electric shock due to incorrectly installed DC link bridges
Incorrectly installed DC link bridges
at the left-hand end of the drive line-up
can cause an
electric shock.
• For all 50 mm wide modules
1)
(exception: Smart Line Module
2)
), remove the DC link
bridge, including the screws. Do not tighten the screws without the DC link bridges.
• For all components that are 75 mm wide or wider, the DC link bridges may neither be
swung over to the left nor removed
3)
.
1)
For 50 mm wide modules, the DC link bridge cannot be swung inwards.
2)
Smart Line modules do not have a DC link bridge.
3)
The DC link bridge guarantees the mechanical stability of the DC link busbars.
