Safety instructions for Adapter Modules
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 are not observed,
accidents involving severe injuries or death may occur.
• Adhere to the fundamental safety instructions.
• When assessing the risk, take into account remaining risks.
Danger to life through 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.
• Open the protective cover of the DC link and only remove/insert the Hybrid Cable after 5
• Before starting any work, also check that the system is in a voltage-free state by
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.
Danger to life in the event of 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

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
