9.2 Safety instructions for Control Supply Modules
Electric shock when live parts are touched when using the Control Supply Module
The Control Supply Module has 2 supply circuits. Touching live components can result in death
or severe 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 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 cover 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 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
Live parts are exposed if the DC link side covers are not fitted. Contact with these live parts could
cause 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 or fire due to missing or unsuitable overcurrent protective device
Overcurrent protective equipment that trips too late or not all can cause electric shock or fire.
• Connect each Control Supply Module via a suitable circuit breaker or safety fuses.
• The types specified in the technical data for the respective module are to be used in this
