Safety information

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 residual charge
A hazardous voltage is still present for up to 5 minutes after the power supply has been
switched off.
Contact with live parts can result in death or serious injury.
• Measure the voltage before starting any work.
Danger to life through interruption of the external protective conductor due to high leakage
currents
The drive components conduct a high leakage current via the protective conductor.
Touching conductive parts when the protective conductor is interrupted can result in death
or serious injury.
• Ensure that the external protective conductor satisfies at least one of the following
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
44
WARNING
DANGER
WARNING
conditions:
– It has been laid so that it is protected against mechanical damage.
– If it is a single cable, it has a cross-section of at least 10 mm² Cu.
– If it is a conductor of a multi-conductor cable, it has a cross-section of at least 2.5
mm² Cu.
– It has a second protective conductor in parallel with the same cross-section.
– It complies with the local regulations for equipment with increased leakage current.
Cables laid within control cabinets or closed machine housings are considered to be
1)
adequately protected against mechanical damage.
WARNING
Ventilation clearances above and below the component (Page 310).
