Danger to life if the fundamental safety instructions and remaining risks are not carefully
observed
If the fundamental safety instructions and remaining risks in Chapter 1 (Page 21) are not
observed, accidents involving severe injuries or death may occur.
• Adhere to the fundamental safety instructions.
• When assessing the risk, take into account residual risks.
Danger to life through 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.
• Only operate the S120 Combi with the DC link protective cover closed.
• Do not continue to operate damaged components.
Danger of an accident due to missing warning labels in the national language.
Missing warning labels in the national language regarding the DC link discharge time can
result in death or serious injury.
• Attach the component warning labels in the national language.
Fire hazard due to overheating because of inadequate ventilation clearances
Inadequate ventilation clearances can cause overheating with a risk for personnel through
smoke development and fire. This can also result in more downtimes and Line Modules
may have a reduced service life.
• It is absolutely essential that you maintain ventilation clearances according to the table
Danger to life through 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.
