WARNING
Danger to life due to electric shock and fire hazard caused by overcurrent protective
equipment tripping too late
Overcurrent protective equipment that trips too late or not all can cause electric shock or
fire.
• To protect personnel and for fire protection purposes, at the infeed point, the short-
circuit rating and loop impedance must match the specifications in the documentation so
that the installed overcurrent protection devices trip within the specified time.
WARNING
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
conductor (see Chapter "Protective connection and equipotential bonding (Page 736)").
WARNING
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.
WARNING
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.
