Legal information
Warning notice system
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
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
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.
Qualified Personnel
The product/system described in this documentation may be operated only by personnel qualified for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.
Qualified personnel are those who, based on their training and experience, are capable of identifying risks and

Safety Instructions
2
2.1 General safety instructions
WARNING
Life-threatening voltages are present with an open control cabinet
When you install the device in a control cabinet, some areas or components in the open
control cabinet may be carrying life-threatening voltages.
If you touch these areas or components, you may be killed by electric shock.
Switch off the power supply to the cabinet before opening it.
WARNING
The installer of the system is responsible for the safety of a system in which the device
is integrated.
There is a risk of malfunction which could result in death or serious injury.
•
Ensure that only suitably qualified personnel perform the work.
System expansions
NOTICE
Damage through system expansions
Device and system expansions may be faulty and can affect the entire machine or plant.
The installation of expansions can damage the device, machine or plant. Device and system
expansions may violate safety rules and regulations regarding radio interference
suppression. If you install or exchange system expansions and damage your device, the
warranty becomes void.
Note the following for system expansions:
•Only install system expansion devices designed for this device. Contact your technical
support team or where you purchased your PC to find out which system expansion devices
may safely be installed.
•Observe the information on electromagnetic compatibility (Page 78).

Safety Instructions
2.1 General safety instructions
SIMATIC IPC427E
16 Operating Instructions, 02/2021, A5E37454814-AE
WARNING
Risk of fire through expansion cards
Expansion cards generate additional heat. The device may overheat and cause a fire.
•Observe the safety and installation instructions for the expansion cards.
•When in doubt, install the device in an enclosure that meets the requirements of
paragraph 9.3.2 of the IEC/UL/EN/DIN-EN 61010-2-201 standard.
Battery and rechargeable battery
WARNING
Risk of explosion and release of harmful substances
Improper handling of lithium batteries can result in an explosion of the batteries.
Explosion of the batteries and the released pollutants can cause severe physical injury. Worn
batteries jeopardize the function of the device.
Note the following when handling lithium batteries:
•Replace used batteries in good time; see the section "Replacing the backup battery" in
the operating instructions.
•Replace the lithium battery only with an identical battery or types recommended by the
manufacturer (order no.: A5E34734290).
•Do not throw lithium batteries into fire, do not solder on the cell body, do not recharge,
do not open, do not short-circuit, do not reverse polarity, do not heat above 100°C and
protect from direct sunlight, moisture and condensation.
High frequency radiation
NOTICE
Unintentional operating situations
High frequency radiation, e g. from a cellular phone, interferes with device functions and
can result in malfunctioning of the device.
Persons are injured and the plant is damaged.
Avoid high-frequency radiation:
•Remove radiation sources from the environment of the device.
•Switch off radiating devices.
•Reduce the radio output of radiating devices.
•
Observe the information on electromagnetic compatibility (Page 78).

Safety Instructions
2.1 General safety instructions
SIMATIC IPC427E
Operating Instructions, 02/2021, A5E37454814-AE 17
ESD Guideline
Electrostatic sensitive devices can be labeled with an appropriate symbol.
NOTICE
Electrostatic sensitive devices (ESD)
When you touch electrostatic sensitive components, you can destroy them through voltages
that are far below the human perception threshold.
If you work with components that can be destroyed by electrostatic discharge, observe the
ESD Guideline (Page 79).
Industrial Security
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 only form one element of such a concept.
Customer is responsible to prevent unauthorized access to its plants, systems, machines and
networks. Systems, machines and components should only be connected to the enterprise
network or the internet if and to the extent necessary and with appropriate security measures
(e.g. use of firewalls and network segmentation) in place.
Additionally, Siemens’ guidance on appropriate security measures should be taken into
