Safety
WARNING
High electric voltage! Danger to life, risk of injury
by electric shock.
−
Life parts are dangerous.
Do not open any covers or flange sockets
during operation.
Never connect or disconnect plug connec-
tors under load!
WARNING
Risk of injury due to rotating motor shaft!
−
Do not remove any covers, machine parts or
protection devices during operation.
Do not enter the range of movement of the
machine. Avoid unintended access for per-
sons, due to
−
Safety fences, safety screens or pro-
tective covers.
−
Optical sensors
CAUTION
Thermal danger due to hot surfaces with temper-
atures over 60 °C during operation
−
Do not touch hot motor surfaces.
Install protection against contact, if neces-
sary.
Make sure that no temperature-sensitive
components (cables, electronic compo-
nents, ...) touch hot surfaces.
All persons working with motors (responsible
persons, mechanics and planners) must have
knowledge, skills and competence according to
EN 60079-14:2014.

Ambient conditions
during operation
Climatic conditions are defined in classes
according to EN
IEC
60721. The classes are
differentiated in the areas storage, transport and
operation. They are based on long-term expe-
riences and take all influencing variables into
account, e.g., air temperature and air humidity.
A permanent use of the motors is possible when
the specified class 3K22 according to EN IEC
60721-3-3:2019 is observed. Deviations and
enhancements according to the follwing table
must be observed.

Vibration load during opera-
tion
Vibrations are sine-wave oscillations in operation,
which vary in their effect on the resistance of the
motors depending on their intensity.
