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
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
with a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken.
CAUTION
without a safety alert symbol, indicates that property damage can result if proper precautions are not taken.
NOTICE
indicates that an unintended result or situation can occur if the corresponding information is not taken into
account.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.

Safety information 1
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
A5E00264365A
8 Siemens AG Operating Instructions 2.02 1PL622
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
A5E00264365A
Siemens AG Operating Instructions 2.02 1PL622 9
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.

1.4 ESD-sensitive components
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
