Safety instructions

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 5 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 flap of the DC link until 5 minutes have elapsed.
• Verify that the DCP and DCN DC link terminals are de-energized before starting any work.
Electric shock when the protective flap of the DC link is open
Contact with live parts can result in death or serious injury.
• Only operate the components with closed protective flap.
Electric shock due to improper DC link connection
Incorrect connections can cause overheating and so fire and smoke development. 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 Siemens
Electric shock due to missing DC link side covers
Live parts are exposed if the DC link side covers are not fitted. Contact could give you an electric
shock.
• Mount the side covers on the first and last component in the drive line-up.
• Order any missing side covers (Article number: 6SL3162-5AA00-0AA0).
Electric shock if the cutout in the protective flap has been broken out
Live components are exposed and accessible if the DC link adapters are removed. Contact with
live parts can result in death or serious injury.
• Replace the protective flap with the broken out cutouts with a new protective flap.
