Safety notes

2.1  Security 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 customers’ exposure to cyber threats.
To stay informed about product updates, subscribe to the Siemens Industrial Security RSS Feed visit (https://www.siemens.com/cert).
2.2  Data protection
Siemens observes the data protection guidelines, especially the requirements regarding data minimization (privacy by design). This means the following for this SIMATIC product: The product does not process / save any personal information, but only technical functional data (e.g. time stamps). If the user links this data to other data (e.g. shift plans) or if the user saves  personal information on the same medium (e.g. hard disk) and therefore creates a personal reference in the process, the user has to ensure meeting the guidelines regarding data protection.
2.3  General safety instructions 
Strong high-frequency radiation  
NOTICE
Observe immunity to RF radiation
The device has an increased immunity to RF radiation according to the specifications on electromagnetic compatibility in the technical specifications.
Radiation exposure in excess of the specified immunity limits can impair device functions, result in malfunctions and therefore injuries or damages.
Read the information on immunity to RF radiation in the technical specifications.
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.
2.4  Notes on connecting 
WARNING 
Risk of fire and electric shock
The on/off switch does not isolate the device from the power supply. Risk of electric shock if the device is opened incorrectly or defective. There is also a risk of fire if the device or connecting lines are damaged. Death or serious bodily injury can result.
You should therefore protect the device as follows:

• Always pull out the power plug when you are not using the device or if the device is defective. The power plug must be freely accessible.
• Use a central power isolating switch for cabinet installation.

WARNING
Risk of lightning strikes
A lightning flash may enter the mains cables and data transmission cables and jump to a person.
Death, serious injury and burns can be caused by lightning.
Take the following precautions:

• Disconnect the device from the power supply in good time when a thunderstorm is approaching.
• Do not touch mains cables and data transmission cables during a thunderstorm.
• Keep a sufficient distance from electric cables, distributors, systems, etc.

Installing and connecting the device

3.1  Preparing for installation
3.1.1  Checking the delivery
Procedure

1. When accepting a delivery, please check the packaging for visible transport damage.
2. If any transport damage is present at the time of delivery, lodge a complaint at the shipping company in charge. Have the shipper confirm the transport damage immediately.
3. Unpack the device at its installation location.
4. Keep the original packaging in case you have to transport the unit again.
   Note
   Damage to the device during transport and storage
   If a device is transported or stored without packaging, shocks, vibrations, pressure and moisture may impact the unprotected unit. A damaged packaging indicates that ambient conditions have already had a massive impact on the device.  The device may be damaged.
   Do not dispose of the original packaging. Pack the device during transportation and storage.
5. Check the contents of the packaging and any accessories you may have ordered for completeness and damage.
6. If the contents of the packaging are incomplete, damaged or do not match your order, inform the responsible delivery service immediately.
   WARNING
   Electric shock and fire hazard due to damaged device
   A damaged device can be under hazardous voltage and trigger a fire in the machine or plant. A damaged device has unpredictable properties and states.
   Death or serious injury could occur. Make sure that the damaged device is not inadvertently installed and put into operation. Label the damaged device and keep it locked away. Send off the device for immediate repair.
   NOTICE
   Damage from condensation
   If the device is subjected to low temperatures or extreme fluctuations in temperature during transportation, for example in cold weather, moisture could build up on or inside the device.
   Moisture causes a short circuit in electrical circuits and damages the device.
   In order to prevent damage to the device, proceed as follows:
   • Store the device in a dry place.
   • Bring the device to room temperature before starting it up.
   • Do not expose the device to direct heat radiation from a heating device.
   • If condensation develops, wait approximately 12 hours or until the device is completely dry before switching it on.
7. Please keep the enclosed documentation in a safe place. It belongs to the device. You need the documentation when you commission the device for the first time.
8. Write down the identification data of the device.
