WARNING
Danger from voltage/current!
Only perform assembly and disassembly work when the device is de-energized.
Only install products with IP20 degree of protection according to IEC 60529 in enclosures, cabinets or electrical operating
rooms suitable for the end application.
CAUTION
The synchronization module contains a laser system and is classified as a "CLASS 1 LASER PRODUCT" in accordance
with IEC 60825-1.
Can cause personal injury.
Avoid eye contact with the laser beam. Do not open the housing. Read the information in the documentation
(https://support.industry.siemens.com/cs/ww/en/view/59191792).
WARNING
Safety functional extra low voltage
The product must be operated with safety functional extra low voltage (SELV, PELV). You can find more information on
safety functional extra low voltage in the documentation (https://support.industry.siemens.com/cs/ww/en/view/59191792)
of the fail-safe I/O and in the data sheets of the power supplies to be used.
Use a power supply unit with output voltage that does not exceed 36 V DC even in the event of a fault.
Follow the notes and warnings in the respective manual.
Electromagnetic Compatibility
The I/O system is intended for operation in the EMC environment class Industry.
Ensure an EMC-compliant design of your automation system as described in the documentation
(https://support.industry.siemens.com/cs/ww/en/view/59191792) for the I/O system.
NOTICE
Interference emission / Interference immunity
The operation of the I/O system can cause radio interference in residential areas.
If higher EMI is expected at the place of use than is intended for the industrial area according to EN61000-6-2, additional
measures are required (e.g. ESD, overvoltage protection).
ATEX-/UKEX device intended for use in hazardous area
If the product is intended for use in a potentially explosive atmosphere (gas/air or gas/dust mixture), observe the special
information in the documentation (https://support.industry.siemens.com/cs/ww/en/view/59191792). The intended use (e.g.
ATEX zone, degree of protection, temperature class) is indicated on the product (in the declaration of conformity and usually
also 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).
WARNING
Pulling or plugging a module is prohibited in the hazardous area.
When you pull or plug a module or plug-in connector during operation, there is a risk of sparking. Sparks can cause an
explosion in the hazardous area; death or serious physical injury as well as damage to property can result.
Do not pull or plug the module or the plug-in connectors until one of the following two conditions is met: The area is no
longer hazardous or the device and its plug-in connectors are de-energized.
Cleaning
If you need to clean the product, use dry ESD cleaning cloths (observing the protective measures for ESD).
