2Security 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. firewalls and/or network segmentation)
are in place.
For additional information on industrial security measures that may be implemented, please visit
https://www.siemens.com/industrialsecurity.
Siemens’ products and solutions undergo continuous development to make them more secure. Siemens strongly
recommends that product updates are applied as soon as they are available and that the latest product versions are used. Use
of product versions that are no longer supported, and failure to apply the latest updates may increase customer’s exposure to
cyber threats.

Electrical safety
For the power supply, the following applies additionally:
WARNING
Connection of the power supply
Only qualified personnel are permitted to connect the power supply. Pay special attention to information in the
Documentation (https://support.industry.siemens.com/cs/in/en/ps/29688/man) and on the nameplate of the device.
Note
The power supply must be connected by the operator/user in accordance with the national regulations regarding installation.
The following applies to all modules:
WARNING
Danger from voltage/current!
Only perform assembly and disassembly work when the device is de-energized.
Set up products with IP54 degree of protection according to IEC 60529 only in enclosures, cabinets or electrical equipment
rooms suitable for the end application.
WARNING
Safety functional extra low voltage
The product must be supplied with functional extra-low voltage (SELV, PELV).
For LV modules, the following applies additionally:
WARNING
Risk of death or serious injury due to electric shock!
Disconnect the system and module before beginning work.
For externally-supplied applications, the following applies additionally:

ET 200PA SMART+ distributed I/O system
A5E52951242-AA, 07/2023 7
For ISOL modules, the following applies additionally:
WARNING
Danger from voltage/current!
The permitted electric potential difference allows an externally supplied voltage to be present at the inputs/outputs even in
switched-off state.
Safety in hazardous areas
If the device is intended for use in hazardous areas (gas-air or gas-dust mixture), note the specific details in the
Documentation (https://support.industry.siemens.com/cs/in/en/ps/29688/man).
You can recognize that the device is intended for use in hazardous areas from the Ex marking in the EC Declaration of
Conformity, in the associated certificate or on the nameplate.
Note
As a rule, country
-specific requirements for the operator also apply when a product is used in a potentially explosive
atmosphere (e.g. Directive 1999/92/EC for the EU).
Laser
The BusAdapter connects the IO device to the IO controller (CPU) via PROFINET IO. The BusAdapter selected for PROFINET IO
determines the cable types used to connect the interface module to the fieldbus.

You can achieve optimal results with respect to a high
-quality and durable electrical connection and maximum conductor
extraction forces at the sam
e time by using crimping dies preferably with smooth surfaces. Options include rectangular and
trapezoidal crimping cross
-sections.
Due to the large number of crimping dies used in the industry, we can recommend others on request.
Crimping dies with a
pronounced wave profile are not permitted in the product.
6Maintenance and repair
The product is maintenance-free. Repairs to the product may only be carried out by the manufacturer.
WARNING
Electromagnetic interference
There is no protection against electromagnetic interference when the control cabinet door is open. The following must be
observed when working inside the control cabinet:
•Turn off mobile phones, radio devices and other devices with strong electromagnetic fields.
The following must be observed when working in hazardous areas
For applications in potentially explosive atmospheres, you must observe the guidelines specified in DIN EN IEC 60079-17
when performing functional checks.
WARNING
Explosion
Devices in hazardous areas require special periodic inspection and testing:
•Only qualified personnel are permitted to perform maintenance and repairs.
•The specific procedure and prescribed methods must be followed.
WARNING
Danger to the system
Fail-safe systems require special periodic inspection and testing:
•Only qualified personnel are permitted to perform maintenance and repairs.
•The specific procedure and prescribed methods must be followed.

7Modification and decommissioning
The following modifications can be dangerous and void the conformity as well as applicable regulations and standards:
•Modification of the I/O system
•Modification of the arrangement of control cabinets
•Modification of the interconnection and selection of electrical components
•Mechanical alteration of the control cabinet
Note
Siemens is not responsible and makes no guarantee for modifications to the configuration that w
as handed over to the
customer.
Only engineers or designers who are familiar with the relevant technologies, regulations and standards are permitted to plan
modifications.
Decommissioning of the I/O system or portions thereof represents a modification.
At least the following points must be taken into consideration when planning modifications:
•Parts of the system may have to be isolated to allow work to be performed safely.
•Parts of the system may have to be shut down for the modification so that operation can be resumed safely.
•Follow the correct order for the modification so that the modification can be carried out safely with regard to electrical
safety, the automation and the system control.
•Pay attention to whether safety functions might be affected by the modification.
•Pay attention to whether explosion-protected systems or hazardous areas are affected.
Hazardous areas are especially critical parts of modifications. The planner must apply utmost care.
It may be necessary to fall back on earlier design and development phases of the system (Safety Life Cycle) to safely deal with
the functional aspects of the modification.
WARNING
Explosion
Explosion-protected systems are of critical importance for plant safety:
•An unauthorized modification immediately discharges the operational approval of the system.
•Only qualified personnel are permitted to make modifications taking into account all system requirements.
