Safety instructions
Required safety precautions before installation work is carried out
Risk of death resulting from failure to observe the general safety instructions and residual
risks
If the general safety instructions and residual risks are not observed, accidents can occur
causing serious injuries or death.
• Observe the general safety instructions.
• Take into account residual risks when assessing risks.
Risk of death from electric shock due to residual charge of the DC link capacitors
Because of the DC link capacitors, a hazardous voltage is still present for a while after
switching off the infeed voltage.
Contact with live parts can result in death or serious injury.
• Open the unit only after the time specified on the warning label has elapsed.
• Before starting work, check the absence of voltage by an all-pole measurement,
including to ground.
Property damage resulting from switching on the device without forming of the DC link
capacitors
After a storage duration exceeding two years, switching on the device without forming of
the DC link capacitors can damage it.
• If the device has been stored for more than two years, form it before switching it on; see
"Maintenance and service".
