WARNING
Danger to life due to fire spreading if housing is inadequate
Fire and smoke development can cause severe personal injury or material damage.
•Install devices without a protective housing in a metal control cabinet (or protect the
device by another equivalent measure) in such a way that contact with fire inside and
outside the device is prevented.
•Additionally, select the installation site so that an uncontrolled spreading of smoke can
be avoided in the case of a fire.
•Ensure that smoke can escape via designated paths.
WARNING
Danger to life through unexpected movement of machines when using mobile wireless
devices or mobile phones
Using mobile wireless devices or mobile phones with a transmitter power > 1 W closer than
approx. 2 m to the components may cause the devices to malfunction and influence the
functional safety of machines, therefore putting people at risk or causing material damage.
•Switch the wireless devices or mobile phones off in the immediate vicinity of the
components.
WARNING
Danger to life due to the motor catching fire in the event of insulation overload
There is a greater load on the motor insulation through a ground fault in an IT system. A
possible result is the failure of the insulation with a risk for personnel through smoke
development and fire.
•Use a monitoring device that signals an insulation fault.
•Correct the fault as quickly as possible so the motor insulation is not overloaded.
WARNING
Danger to life due to fire if overheating occurs because of insufficient ventilation clearances
Inadequate ventilation clearances can cause overheating with a risk for personnel through
smoke development and fire. This can also result in increased downtime and reduced
service lives for devices / systems.
•Ensure compliance with the specified minimum clearance as ventilation clearance for
the respective component. They can be found in the dimension drawings or in the
"Product-specific safety instructions" at the start of the respective section.

1.4
Residual risks of power drive systems
The control and drive components of a drive system are approved for industrial and
commercial use in industrial line supplies. Their use in public line supplies requires a
different configuration and/or additional measures.
These components may only be operated in closed housings or in higher-level control
cabinets with protective covers that are closed, and when all of the protective devices are
used.
These components may only be handled by qualified and trained technical personnel who
are knowledgeable and observe all of the safety instructions on the components and in the
associated technical user documentation.
When assessing the machine's risk in accordance with the respective local regulations
(e.g., EC Machinery Directive), the machine manufacturer must take into account the
following residual risks emanating from the control and drive components of a drive system:
1. Unintentional movements of driven machine components during commissioning,
operation, maintenance, and repairs caused by, for example:
–Hardware defects and/or software errors in the sensors, controllers, actuators, and
connection technology
–Response times of the controller and drive
–Operating and/or ambient conditions outside of the specification
–Condensation / conductive contamination
–Parameterization, programming, cabling, and installation errors
–Use of radio devices / cellular phones in the immediate vicinity of the controller
–External influences / damage
2. In the event of a fault, exceptionally high temperatures, including an open fire, as well as
emissions of light, noise, particles, gases, etc. can occur inside and outside the inverter,
e.g.:
–Component malfunctions
–Software errors
–Operating and/or ambient conditions outside of the specification
