Electric shock when live parts are touched when using the Control Supply Module
The Control Supply Module has two supply circuits. Contact with live parts can result in
death or serious injury.
• Switch off both supply circuits before you start any work.
Electric shock due to the residual charge of the DC-link capacitors
Due to the DC-link capacitors, a hazardous voltage is present in the DC link 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.
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.
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 supplied side covers on the first and last component in the drive line-up.
Missing warning labels in the national language
Missing or illegible warning labels in the national language regarding the DC-link discharge
time can result in death or serious injury.
