5. Damage from pressure build-up during electric arcs in the event of a fault
If the building has not been designed correctly for the drive in terms of how it has been
dimensioned, damage can result from the pressure that can possibly build up inside.
6.
Dangerous electric arcs during internal faults
The drives are designed according to the relevant IEC standards and have been tested in
line with strict type-testing procedures. They were developed and manufactured so that
there is a very low probability of internal faults occurring. However, internal faults cannot
be completely ruled out.
WARNING
Dangerous electric arcs during internal faults
Defects
such as damage to components, overvoltages, or loose parts, as well as exceptional
operating statuses, can cause a failure within the enclosure. This can result in an internal
electric arc. If an electric arc occurs and people are nearby, this could lead to death, serious
physical injury, and damage to property.
● Ensure that only qualified personnel perform work on the drive.
● Observe the safety and operating instructions in this documentation and on labels at the
drive for all work on the drive.
