Safety Guidelines
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING

Safety information
1.1 Observing the five safety rules
For your personal safety and to prevent material damage when working on the device,
always observe the safety instructions on the product and the following five safety rules: You
must read the information provided in "Safety information".
The five safety rules:
1. isolate,
2. Protect against reconnection,
3. verify that the equipment is not live,
4. Ground and short circuit,
5. Cover or enclose adjacent components that are still live
Qualified personnel
Commissioning and operation of this machine are to be carried out by qualified personnel
only. For the purpose of the safety information in this Instruction Manual, a “qualified person”
is someone who is authorized to energize, ground, and tag equipment, systems, and circuits
in accordance with established safety procedures.

1.2 Safety and application instructions
The safe use of electrical machines
WARNING
Rotating or live parts
Rotating or live parts are dangerous.
Fatal or severe injuries and substantial material damage can occur if the required covers
are removed or if the machines are not handled, operated, or maintained properly.
Only remove covers in accordance with regulations and operate machines correctly.
Perform regular maintenance on the machine.

Safety information
1.2 Safety and application instructions
Qualified personnel
These operating instructions only contain the information that is necessary for the machines
to be used by qualified personnel in accordance with their intended purpose.
Those responsible for plant safety must ensure the following:
● The basic planning work for the system and all work relating to transportation, assembly,
installation, commissioning, maintenance and repairs is carried out by qualified personnel
and checked by responsible, suitably skilled personnel.
● The operating instructions and machine documentation are always available.
● The technical data and specifications relating to installation, connection, ambient and
operating conditions are taken into account at all times.
● The system-specific installation and safety regulations are observed.
● Personal protective equipment is used.
● Work on or in the vicinity of these machines by unqualified persons is prohibited.
● If the machines are used outside industrial areas, the installation site must be
safeguarded against unauthorized access by means of suitable protection facilities (e.g.,
safety gates) and appropriate warning signs.

These operating instructions therefore only contain the information which is necessary for
the machines to be used by qualified persons in accordance with their intended purpose.
Note
Siemens Service Center
We recommend engaging the support and services of your local Siemens Service Center for
all planning, installation, commissioning, and maintenance work.

Safety information
1.3 Electromagnetic fields
1.3 Electromagnetic fields
Safety information
WARNING
Electromagnetic fields "electro smog"
Electromagnetic fields are generated by the operation of electrical power engineering
installations such as transformers, converters or motors.
Electromagnetic fields can interfere with electronic devices, which could cause them to
malfunction. For example, the operation of heart pacemakers can be impaired, potentially
leading to damage to a person's health or even death. It is therefore forbidden for persons
with heart pacemakers to enter these areas.
The plant operator is responsible for taking appropriate measures (labels and hazard
warnings) to adequately protect operating personnel and others against any possible risk.
● Observe the relevant nationally applicable health and safety regulations. In Germany,
"electromagnetic fields" are subject to regulations BGV B11 and BGR B11 stipulated by
the German statutory industrial accident insurance institution.
● Display adequate hazard warning notices.
● Place barriers around hazardous areas.
● Take measures, e.g. using shields, to reduce electromagnetic fields at their source.
● Make sure that personnel are wearing the appropriate protective gear.

ESD guidelines
CAUTION
Electrostatic discharge
Electronic modules contain components that can be destroyed by electrostatic discharge.
These modules can be easily destroyed by improper handling.
To protect your equipment against damage, follow the instructions given below.
● Never touch electronic modules unless absolutely necessary in the course of
maintenance and repair procedures.
● If the modules have to be touched, the body of the person concerned must be
electrostatically discharged immediately beforehand and be grounded.
● Electronic modules should not be brought into contact with electrically insulating materials
such as plastic foil, plastic parts, insulating table supports or clothing made of synthetic
fibers.
● Always place electrostatic endangered assemblies on conductive bases.
● Always store and transport electronic modules or components in conductive packaging
(e.g. metallized plastic or metal containers).
Note
If the modules are to be stored and/or transported in non-conducting packings anyway,
they must be wrapped in conducting materials before doing so. Always use suitable
material for this purpose, for example, conductive foam rubber or household aluminum
foil.
The necessary ESD protective measures for electrostatically sensitive devices are illustrated

① Cover sheet
② Cooling flow
A KTY 84 temperature sensor is installed in the stator winding to monitor the winding.
Depending on the order, various additional devices such as sensor systems can be installed
or built on.
NOTICE
A minimum clearance of 100 mm from devices added on by the customer must be
observed at the air intake opening and at the air outlet openings, in order to guarantee the
necessary flow of cooling air.
Securing the cooling capacity
CAUTION
Missing cover sheets can result in considerably reduced cooling capacity and thus cause
an inadmissible temperature rise within the motor.
Please ensure that the cover sheets are always mounted.

Transport, assembly, and connection
3.1 Transport, storage, and maintenance
Transporting motors with a rotor shipping brace
Motors with cylindrical-roller bearings have a rotor shipping brace (shaft block), in order to
prevent the bearings from becoming damaged during transportation/shipping.
● Only remove this brace before fitting the drive element.
[ID: 325.01]
3.1.2 Storage
CAUTION
Seizure damage to friction bearings and rolling-contact bearings
If storage conditions are inappropriate there is a risk of bearing seizure damage. This can
result in brinelling, for example.
Read the following notes on storage.
Storing outdoors
Store the machine in a location that meets the following criteria:
NOTICE
Take other suitable measures to axially fix the rotor if the motor has to be transported
after you have fitted the drive element.
Storing indoors
● Choose a dry storage location with plenty of space, which is safe from flooding and free
from vibrations.
● Repair any damage to the packaging before putting the equipment into storage insofar as
this is necessary to ensure proper storage conditions.
● Position machines, devices, and crates on pallets, wooden beams or foundations that
guarantee protection against ground dampness.
● Prevent the machine sinking into the ground.
● Ensure that the air circulation under the equipment is not impeded.
– Covers or tarpaulins used to protect the equipment against the weather must not
make contact with the surfaces of the equipment.
– Covers or tarpaulins must not trail on the floor around the machine.
– Place wooden spacer blocks between the covers and the machine.
● Store the machine in a room that meets the following criteria:
– Dry, dust-free, frost-free and vibration-free
– Well ventilated
