3.2 Safety instructions for Motor Modules of C/D-type
Electric shock caused by a high DC link voltage
As long as the Line Module is connected to the line supply, the DC link is charged with a
high voltage, and as a consequence, also the Motor Module. A hazardous voltage can be
present independent of the status of the LED "DC LINK" Contact with live parts and
components can result in death or severe injury.
• Isolate the Line Module from the line supply during installation or maintenance work,
• Observe the warning information on the component.
Electric shock when the protective cover of the DC link is open
Live parts of the DC link are freely exposed when operating Motor Modules with open
protective flap. Contact with live parts can result in death or serious injury.
• Only operate the components with closed protective cover.
Electric shock or fire caused by the DC link being incorrectly connected
Incorrectly established connections can result in overheating and therefore 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) approved by
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.
