Danger to life through electric shock due to the residual charge of the DC-link capacitors
Because of the DC-link capacitors, a hazardous voltage is present for up to five minutes
after the power supply has been switched off.
Contact with live parts can result in death or serious injury.
• Do not open the protective cover of the DC link until five minutes have elapsed.
• Measure the voltage before starting work on the DCP and DCN DC-link terminals.
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 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
• For all components that are 75 mm wide or wider, the DC-link bridges may neither be
For 50 mm wide modules, the DC-link bridge cannot be swung inwards.
1)
Smart Line Modules do not have a DC-link bridge.
2)
The DC-link bridge guarantees the mechanical stability of the DC-link busbars.
3)
Danger to life through 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 (order number: 6SL3162-5AA00-0AA0).
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.
• When connecting to the DC link, only use the adapter that has been approved by
