Safety and application information

The safe use of electrical machines
Danger
These electrical machines are designed
for use in industrial power systems.
Rotating or live and uninsulated parts
pose a danger.
There is consequently a risk of
fatal or severe personal injury or
substantial damage to property if the
necessary covers are removed without
authorization or if the equipment
is handled improperly, operated
incorrectly or maintained inadequately.
If the motors are used outside industrial
areas, the installation site must be
safeguarded against unauthorized
access by means of suitable protection
facilities (e.g. fencing) and appropriate
warning signs.
The persons responsible for the safety
of the system are under an obligation to
ensure that:
• The basic planning work for the system
and all work relating to transportation,
assembly, installation, commissioning,
maintenance and repairs are carried out
by qualified persons and checked by
responsible, suitably skilled persons.
• These instructions and the motor
documentation are made available at all
times while work is in progress.
• The technical data and specifications
relating to the permissible installation,
connection, ambient and operating
conditions are taken into account at all
times.
• The system-specific erection and safety
regulations are observed and personal
protective gear is used.
• Work on these machines, or in
the vicinity of these machines, by
unqualified persons is prohibited.
These instructions therefore only contain
the information, which is necessary for the
motors to be used by qualified persons in
accordance with their intended purpose.
Note
We recommend engaging the support
and services of your local SIEMENS service
center for all planning, installation,
commissioning and maintenance work.

Other constructions are given on customer
request.
Unless otherwise specified, the rated
outputs apply to continuous duty (S1) at a
frequency of 50 Hz, an ambient temperature
between 0°C and 50°C and site altitude not
exceeding 1000m above mean sea level.
