Connecting up, switching on
Line and motor connections can be established once the converter has been properly
installed. It is crucial that the following notes are observed.
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.
• Only open the device after five minutes have elapsed.
• Measure the voltage before starting work on the DCP and DCN DC link terminals.
Danger of an accident due to missing warning labels in the national language.
Missing warning labels in the national language can result in death or serious injury.
• Attach the component warning labels in the national language.
Converter damaged due to overvoltage
Line-side overvoltages can damage the converter.
• Install the surge voltage protection device directly at the infeed point (before the main
switch).
Note
Ensure that the appropriate circuit breakers or fuses with the specified current rating are
connected between
the power supply and the drive. The technical data contain information
about the circuit breaker and fuses (see Specifications).
