Compliance with the General Data Protection Regulation
Siemens observes standard data protection principles, in particular the data minimization rules
(privacy by design).
For this product, this means:
The product does not process or store any personal data, only technical function data (e.g. time
stamps). If the user links this data with other data (e.g. shift plans) or if he/she stores personrelated data on the same data medium (e.g. hard disk), thus personalizing this data, he/she must
ensure compliance with the applicable data protection stipulations.
Electric shock and danger to life due to other energy sources
Touching live components can result in death or severe injury.
• Only work on electrical devices when you are qualied for this job.
• Always observe the country-specic safety rules.
Generally, the following steps apply when establishing safety:
1. Prepare for disconnection. Notify all those who will be aected by the procedure.
2. Isolate the drive system from the power supply and take measures to prevent it being
switched back on again.
3. Wait until the discharge time specied on the warning labels has elapsed.
4. Check that there is no voltage between any of the power connections, and between any of
the power connections and the protective conductor connection.
5. Check whether the existing auxiliary supply circuits are de-energized.
6. Ensure that the motors cannot move.
7. Identify all other dangerous energy sources, e.g. compressed air, hydraulic systems, or
water. Switch the energy sources to a safe state.
8. Check that the correct drive system is completely locked.

After you have completed the work, restore the operational readiness in the inverse sequence.
WARNING
Electric shock due to connection to an unsuitable power supply
When equipment is connected to an unsuitable power supply, exposed components may carry
a hazardous voltage. Contact with hazardous voltage can result in severe injury or death.
• Only use power supplies that provide SELV (Safety Extra Low Voltage) or PELV- (Protective
Extra Low Voltage) output voltages for all connections and terminals of the electronics
modules.
Improper handling may cause damage to equipment. For damaged devices, hazardous
voltages can be present at the enclosure or at exposed components; if touched, this can result
in death or severe injury.
• Ensure compliance with the limit values specied in the technical data during transport,
storage and operation.
• Do not use any damaged devices.
WARNING
Electric shock due to unconnected cable shields
Hazardous touch voltages can occur through capacitive cross-coupling due to unconnected
cable shields.
• As a minimum, connect cable shields and the cores of cables that are not used at one end
at the grounded housing potential.
WARNING
Electric shock if there is no ground connection
For missing or incorrectly implemented protective conductor connection for devices with
protection class I, high voltages can be present at open, exposed parts, which when touched,
can result in death or severe injury.
• Ground the device in compliance with the applicable regulations.
NOTICE
Damage to equipment due to unsuitable tightening tools.
Unsuitable tightening tools or fastening methods can damage the screws of the equipment.
• Be sure to only use screwdrivers which exactly match the heads of the screws.
• Tighten the screws with the torque specied in the technical documentation.
• Use a torque wrench or a mechanical precision nut runner with a dynamic torque sensor and
speed limitation system.
In the event of re outbreak, the enclosures of built-in devices cannot prevent the escape of
re and smoke. This can result in serious personal injury or property damage.
• Install built-in units in a suitable metal cabinet in such a way that personnel are protected
against re and smoke, or take other appropriate measures to protect personnel.
• Ensure that smoke can only escape via controlled and monitored paths.
WARNING
Unexpected movement of machines caused by radio devices or mobile phones
Using radio devices or mobile telephones in the immediate vicinity of the components can
result in equipment malfunction. Malfunctions may impair the functional safety of machines
and can therefore put people in danger or lead to property damage.
• Therefore, if you move closer than 20 cm to the components, be sure to switch o radio
devices or mobile telephones.
• Use the "SIEMENS Industry Online Support app" only on equipment that has already been
switched o.
WARNING
Fire due to inadequate ventilation clearances
Inadequate ventilation clearances can cause overheating of components with subsequent re
and smoke. This can cause severe injury or even death. This can also result in increased
downtime and reduced service lives for devices/systems.
• Ensure compliance with the specied minimum clearance as ventilation clearance for the
respective component.
NOTICE
Overheating due to inadmissible mounting position
The device may overheat and therefore be damaged if mounted in an inadmissible position.
• Only operate the device in admissible mounting positions.
2.2Equipment damage due to electric elds or electrostatic discharge
Electrostatic sensitive devices (ESD) are individual components, integrated circuits, modules or
devices that may be damaged by either electric elds or electrostatic discharge.
NOTICE
Equipment damage due to electric elds or electrostatic discharge
Electric elds or electrostatic discharge can cause malfunctions through damaged individual
components, integrated circuits, modules or devices.
• Only pack, store, transport and send electronic components, modules or devices in their
original packaging or in other suitable materials, e.g conductive foam rubber of aluminum
foil.
• Only touch components, modules and devices when you are grounded by one of the
following methods:
– Wearing an ESD wrist strap
– Wearing ESD shoes or ESD grounding straps in ESD areas with conductive ooring
• Only place electronic components, modules or devices on conductive surfaces (table with
ESD surface, conductive ESD foam, ESD packaging, ESD transport container).
2.3Warranty and liability for application examples
Application examples are not binding and do not claim to be complete regarding conguration,
equipment or any eventuality which may arise. Application examples do not represent specic
customer solutions, but are only intended to provide support for typical tasks.
As the user you yourself are responsible for ensuring that the products described are operated
correctly. Application examples do not relieve you of your responsibility for safe handling when
using, installing, operating and maintaining the equipment.
2.4Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is necessary
to implement – and continuously maintain – a holistic, state-of-the-art industrial security
concept. Siemens’ products and solutions constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be connected to
an enterprise network or the internet if and to the extent such a connection is necessary and only
when appropriate security measures (e.g. rewalls and/or network segmentation) are in place.
For additional information on industrial security measures that may be implemented, please
