5.2 Safety instructions for High Frequency Modules
Electric shock due to high leakage currents caused by an interrupted external protective
conductor
Drive components conduct high discharge currents via the protective conductor. When the
protective conductor is interrupted, touching live components can result in electric shock,
which can lead to death or serious injuries.
• Ensure that the external protective conductor complies with at least one of the following
Electric shock when the protective cover of the DC link is open
Contact with live parts can result in death or serious injury.
• Only operate the components with the protective cover of the DC link components closed.
Electric shock due to incorrect connection to the DC link
Incorrectly established connections can result in overheating and therefore fire with associated
smoke. Further, there is risk of electric shock. This can result in severe injury or death.
• To connect to the DC link, only use the adapters that have been released for the purpose (DC
Electric shock due to missing DC link side covers
If the DC link side covers are missing, there is a risk of electric shock when coming into contact
with the DC link.
• Mount the side covers supplied with the equipment at the first and last component in the
Order any missing side covers (Article number: 6SL3162-5AA00-0AA0).

– It is laid protected against mechanical damage.
– If it consists of a single conductor, it has a cross section of at least 6 mm² Cu.
– As a core of a multi-core cable, it has a cross section of at least 2.5 mm² Cu.
– It has a parallel, second protective conductor with the same cross-section.
– It corresponds to the local regulations for equipment with increased leakage current.
Cables routed in control cabinets or enclosed machine enclosures are considered to be
