CAUTION
Electrostatic sensitive devices (ESD) are single components, integrated circuits or devices
that can be damaged by electrostatic fields or electrostatic discharges.
Regulations for the ESD handling:
During the handling of electronic components, pay attention to the grounding of the person,
workplace and packaging!
Electronic components may be touched by persons only when
•these persons are grounded using an ESD bracelet, or
•these persons in ESD areas with a conducting floor wear ESD shoes or ESD grounding
straps.
Electronic components should be touched only when this is unavoidable. The touching is
permitted only on the front panel or on the circuit board edge.
Electronic components must not be brought into contact with plastics or clothing made of
artificial fibers.
Electronic components may only be placed on conducting surfaces (table with ESD coating,
conducting ESD foamed material, ESD packing bag, ESD transport container).
Electronic components may not be placed near display units, monitors or televisions
(minimum distance from the 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).

DANGER
•Commissioning is absolutely prohibited until it has been completely ensured that the
machine, in which the components described here are to be installed, is in full
compliance with the provisions of the EC Machinery Directive.
•SINAMICS devices and AC motors 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 follow the specified danger and
warning notices.
•When electrical equipment and motors are operated, the electrical circuits automatically
conduct a dangerous voltage.
•When the machine or system is operated, hazardous axis movements can occur.
•All of the work carried-out on the electrical machine or system must be carried-out with it
in a no-voltage condition.
•SINAMICS devices with three-phase motors must only be connected to the power
supply via an AC-DC residual-current-operated device with selective switching once
verification has been provided that the SINAMICS device is compatible with the
residual-current-operated device in accordance with IEC 61800-5-1, Section 5.2.11.2.
WARNING
•The successful and safe operation of this equipment and motors is dependent on
correct transport, proper storage, installation and mounting as well as careful operator
control, service and maintenance.
•For special versions of the drive units and motors, information and data in the Catalogs
and quotations additionally apply.
•In addition to the danger and warning information provided in the technical customer
documentation, the applicable national, local, and plant-specific regulations and
requirements must be taken into account.
•Only protective extra-low voltages (PELV, DVC-A) that comply with EN 60204-1:2006
can be connected to the connections and terminals between 0 V and 48 V.
CAUTION
•The motors can have surface temperatures of over +80 °C.
•This is the reason that temperature-sensitive components, e.g. cables or electronic
components may neither be in contact nor be attached to the motor.
•When attaching the connecting cables, you must ensure that:
– they are not damaged,
– they are not under tension,
– they cannot come into contact with any rotating parts.

Standards and regulations 1
1.1 General information
1.1.1 Aims
Manufacturers and operating companies of equipment, machines, and products are
responsible for ensuring the required level of safety. This means that plants, machines, and
other equipment must be designed to be as safe as possible in accordance with the current
state of the art. To ensure this, companies describe in the various standards the current
state of the art covering all aspects relevant to safety. When the relevant Standards are
observed, this ensures that state-of-the-art technology has been utilized and, in turn, the
erector/builder of a plant or a manufacturer of a machine or a piece of equipment has fulfilled
his appropriate responsibility.
Safety systems are designed to minimize potential hazards for both people and the
environment by means of suitable technical equipment, without restricting industrial
production and the use of machines more than is necessary. The protection of man and
environment must be assigned equal importance in all countries, which is it is important that
rules and regulations that have been internationally harmonized are applied. This is also
designed to avoid distortions in the competition due to different safety requirements in
different countries.
There are different concepts and requirements in the various regions and countries of the
world when it comes to ensuring the appropriate degree of safety. The legislation and the
requirements of how and when proof is to be given and whether there is an adequate level of
safety are just as different as the assignment of responsibilities.
The most important thing for manufacturers of machines and companies that set up plants
and systems is that the legislation and regulations in the country where the machine or plant
is being operated apply. For example, the control system for a machine that is to be used in
the US must fulfill local US requirements even if the machinery construction company (OEM)
is based in the European Economic Area (EEA).

Standards and regulations
1.2 Safety of machinery in Europe
Safety Integrated
18 Function Manual, (FHS), 11/2009, 6SL3097-4AR00-0BP0
1.1.2 Functional safety
Safety, from the perspective of the object to be protected, cannot be split-up. The causes of
hazards and, in turn, the technical measures to avoid them can vary significantly. This is why
a differentiation is made between different types of safety (e.g. by specifying the cause of
possible hazards). "Functional safety" is involved if safety depends on the correct function.
To ensure the functional safety of a machine or plant, the safety-related parts of the
protection and control devices must function correctly. In addition, the systems must behave
in such a way that either the plant remains in a safe state or it is brought into a safe state if a
fault occurs. In this case, it is necessary to use specially qualified technology that fulfills the
requirements described in the associated Standards. The requirements to achieve functional
safety are based on the following basic goals:
● Avoiding systematic faults
● Controlling systematic faults
● Controlling random faults or failures
Benchmarks for establishing whether or not a sufficient level of functional safety has been
achieved include the probability of hazardous failures, the fault tolerance, and the quality that
is to be ensured by minimizing systematic faults. This is expressed in the Standards using
different terms. In IEC/EN 61508, IEC/EN 62061, IEC/EN 61800-5-2: "Safety Integrity Level"
(SIL) and
EN ISO 13849-1:2006: "Categories" and "Performance Level" (PL).
1.2 Safety of machinery in Europe
The EU Directives that apply to the implementation of products are based on Article 95 of the
EU contract, which regulates the free exchange of goods. These are based on a new global
concept ("new approach", "global approach"):
● EU Directives only specify general safety goals and define basic safety requirements.
● Technical details can be defined by means of standards by Standards Associations that
have the appropriate mandate from the commission of the European Parliament and
Council (CEN, CENELEC). These standards are harmonized in line with a specific
directive and listed in the official journal of the commission of the European Parliament
and Council. Legislation does not specify that certain standards have to be observed.
When the harmonized Standards are observed, it can be assumed that the safety
requirements and specifications of the Directives involved have been fulfilled.
● EU Directives specify that the Member States must mutually recognize domestic
regulations.
The EU Directives are equal. This means that if several Directives apply for a specific piece
of equipment or device, the requirements of all of the relevant Directives apply (e.g. for a
machine with electrical equipment, the Machinery Directive and the Low-Voltage Directive
apply).

Function Manual, (FHS), 11/2009, 6SL3097-4AR00-0BP0 19
1.2.1 Machinery Directive
The basic safety and health requirements specified in Annex I of the Directive must be
fulfilled for the safety of machines.
The protective goals must be implemented responsibly to ensure compliance with the
Directive.
Manufacturers of a machine must verify that their machine complies with the basic
requirements. This verification is facilitated by means of harmonized standards.
1.2.2 Harmonized European Standards
The two Standards Organizations CEN (Comité Européen de Normalisation) and CENELEC
(Comité Européen de Normalisation Électrotechnique), mandated by the EU Commission,
drew-up harmonized European standards in order to precisely specify the requirements of
the EC directives for a specific product. These standards (EN standards) are published in the
official journal of the commission of the European Parliament and Council and must be
included without revision in domestic standards. They are designed to fulfill basic health and
safety requirements as well as the protective goals specified in Annex I of the Machinery
Directive.
When the harmonized standards are observed, it is "automatically assumed" that the
Directive is fulfilled. As such, manufacturers can assume that they have observed the safety
aspects of the Directive under the assumption that these are also covered in this standard.
However, not every European Standard is harmonized in this sense. Key here is the listing in
the official journal of the commission of the European Parliament and Council.
The European standards regarding the safety of machines are structured in a hierarchical
manner as follows:
● A standards (basic standards)
● B standards (group standards)
● C standards (product standards)
Type A standards/basic standards
A standards include basic terminology and definitions relating to all types of machine. This
includes EN ISO 12100 (previously EN 292) "Safety of Machines, Basic Terminology,
General Design Principles."
A standards are aimed primarily at the bodies responsible for setting the B and C standards.
The measures specified here for minimizing risk, however, may also be useful for
manufacturers if no applicable C standards have been defined.

Type B standards/group standards
B standards cover all safety-related standards for various different machine types. B
standards are aimed primarily at the bodies responsible for setting C standards. They can
also be useful for manufacturers during the machine design and construction phases,
however, if no applicable C standards have been defined.
A further sub-division has been made for B standards:
● Type B1 standards for higher-level safety aspects (e.g. ergonomic principles, safety
clearances from sources of danger, minimum clearances to prevent parts of the body
from being crushed).
● Type B2 standards for protective safety devices are defined for different machine types
(e.g. EMERGENCY STOP devices, two-hand operating circuits, interlocking elements,
contactless protective devices, safety-related parts of controls).
Type C standards/product standards
C standards are product-specific standards (e.g. for machine tools, woodworking machines,
elevators, packaging machines, printing machines, etc.). Product standards list requirements
for specific machines. The requirements can, under certain circumstances, deviate from the
basic and group standards. Type C/product standards have the highest priority for machine
manufacturers who can assume that it fulfills the basic requirements of Annex I of the
Machinery Directive (automatic presumption of compliance). If no product standard has been
defined for a particular machine, type B standards can be applied when the machine is
constructed.

Recommendation: Due to the rapid pace of technical development and the associated
changes in machine concepts, the standards (and C standards in particular) should be
checked to ensure that they are up to date. Please note that the application of a particular
standard may not be mandatory provided that all the safety requirements of the applicable
EU directives are fulfilled.
