Danger to life as a result of high voltages at the capacitors and in the DC link
High voltages are still present at the capacitors of the power cell and at the DC link even after
the system has been shut down. Touching live parts can result in death or serious injury.
● A label on the drive specifies the discharge times of the DC link capacitors. Only open the
● Observe the five safety rules when performing any work.
Electric shock caused by dangerous auxiliary voltages
Danger voltages are still present even after shutdown. Touching live parts can result in death
or serious injury.
● Carefully comply with the 5 safety rules.
Danger caused by arcing
Hazards caused by arcing can occur as result of the following factors, for example:
Input currents above the permissible limits, incorrectly dimensioned circuit breakers or
transformers, incorrectly connected or unconnected cables, dirt, objects that have been
forgotten, e.g. tools used for installation.
Arcing can result in death, serious injury or material damage.
● As system operator, carefully ensure that the system has been professionally designed and
● Correctly connect the power cables. The maximum permissible input currents are listed in
● Remove contamination and dirt.
● After installation and mounting, carefully check that no objects have been left in the device.
Burns caused by fire escaping from the pressure relief flaps
Fire can escape through the pressure relief flaps if arcing occurs. Persons who are on the roof
section of the drive can suffer severe burns. Objects that are on the roof section of the drive can
catch fire or be flung into the room. Death, serious injury or material damage can result.
● Never climb on the drive. Never place any objects on the roof section of the drive.
Danger due to live stationary parts, moving or rotating parts
Contact with the parts mentioned can result in death, serious physical injury or damage to
property.
● Observe the instructions regarding installation and operation.
● Always take protective measures before touching any components.
● Do not remove any covers.
