Safety guidelines
This Manual contains information which you should carefully observe to ensure your own personal safety and the
prevention of material damage. Notices which are relevant to your own personal safety are highlighted by a safety
alert symbol; notices which are relevant only to equipment and property damage have no safety alert symbol. The
warnings appear in decreasing order of risk as given below.
Danger
"Danger" indicates that death or severe personal injury will result if proper precautions are not taken.
Alarm
"Warning" indicates that death or severe personal injury can result if proper precautions are not taken.
Caution
“Caution” with a warning triangle indicates that minor personal injury can result if proper precautions are not
taken.
Caution
"Caution" without a warning triangle indicates that material damage can result if proper precautions are not taken.
Notice
“Important” indicates that an unwanted result or situation can result if the appropriate advice is not taken into
account.
If several hazards of different degrees occur, the hazard with the highest degree must always be given priority. A
warning notice accompanied by a safety alert symbol indicating a risk of bodily injury can also indicate a risk of
property damage.
Qualifiziertes Personal
The associated device/system may only be set up and operated using this documentation. The device/system
must only be commissioned and operated by qualified personnel. Qualified persons are defined as persons who
are authorized to commission, to ground, and to tag circuits, equipment, and systems in accordance with

Foreword
Information on the SINAMICS S documentation
The SINAMICS S documentation is divided into the following areas:
•General Documentation / Catalogs
•Manufacturer/service documentation
•Electronic documentation
This documentation is an integral part of the manufacturer/service documentation developed
for SINAMICS. All documents can be obtained separately.
You can obtain detailed information about the documents named in the documentation
overview and other documents available for SINAMICS from your local Siemens office.
For the sake of simplicity, this documentation does not contain all detailed information about
all types of the product and cannot cover every conceivable case of installation, operation, or
maintenance.
The contents of this documentation are not part of an earlier or existing agreement, a
promise, or a legal agreement, nor do they change this. All obligations entered into by
Siemens result from the respective contract of sale that contains the complete and sole valid
warranty arrangements. These contractual warranty provisions are neither extended nor
curbed as a result of the statements made in this documentation.
Audience
This documentation is aimed at machine and plant builders, commissioning engineers, and
service personnel who use SINAMICS.
Objective
This manual describes the hardware components of the SINAMICS S system. It provides
information about installation, electrical connection, and cabinet design.

ESD notices
Caution
Electrostatic sensitive devices (ESDs) are individual components, integrated circuits, or
boards that may be damaged by either electrostatic fields or electrostatic discharge.
Regulations for handling ESD components:
•When handling electronic components, you must ensure that the person carrying out the
work, the work place, and packaging are properly grounded.
•Personnel in ESD areas with conductive flooring may only handle electronic components
if:
•They are grounded with an ESD wrist band
•They are wearing ESD shoes or ESD shoe grounding straps
•Electronic boards should only be touched if absolutely necessary. They must only be
handled on the front panel or, in the case of printed circuit boards, at the edge.
•Electronic boards must not come into contact with plastics or items of clothing containing
synthetic fibers.
•Boards must only be placed on conductive surfaces (work surfaces with ESD surface,
conductive ESD foam, ESD packing bag, ESD transport container).
•Do not place boards near display units, monitors, or television sets (minimum distance
from screen: 10 cm).
•Measurements must only be taken on boards when the measuring instrument is
grounded (via protective conductors, for example) or the measuring probe is briefly
discharged before measurements are taken with an isolated measuring device (for
example, touching a bare metal housing).

Safety information
Danger
Commissioning shall not start until you have ensured that the machine in which the
components described here are to be installed complies with Directive 98/37/EC.
SINAMICS S equipment must only be commissioned by suitably qualified personnel.
The personnel must take into account the information provided in the technical customer
documentation for the product, and be familiar with and observe the specified danger and
warning notices.
When electrical equipment and motors are operated, the electrical circuits automatically
conduct a dangerous voltage.
Dangerous mechanical movements may occur in the system during operation.
All work on the electrical system must be carried out when the system has been
disconnected from the power supply.
Alarm
Correct and safe operation of SINAMICS S equipment assumes correct transportation,
storage, setup, and installation, as well as careful operation and maintenance.
The details in the catalogs and proposals also apply to the design of special equipment
versions.
In addition to the danger and warning information provided in the technical customer
documentation, the applicable national, local, and system-specific regulations and
requirements must be taken into account.
Only protective extra-low voltages (PELVs) that comply with EN60204-1 must be connected
to all connections and terminals between 0 and 48 V.
Note
When operated in dry operating areas, SINAMICS equipment with three-phase motors
conforms to low-voltage Directive 73/23/EEC.
SINAMICS equipment with three-phase motors conforms to EMC Directive 89/336/EEC in
the configurations specified in the associated EC Certificate of Conformity.
Caution
Operating the equipment in the immediate vicinity (< 1.5 m) of mobile telephones with a
transmitter power of > 1 W may lead to incorrect operation.
