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.

1	Fundamental safety instructions

1.1General safety instructions

WARNING

Risk of death if the safety instructions and remaining risks are not carefully observed

If the safety instructions and residual risks are not observed in the associated hardware documentation, accidents involving severe injuries or death can occur.

•Observe the safety instructions given in the hardware documentation.

•Consider the residual risks for the risk evaluation.

WARNING

Danger to life or malfunctions of the machine as a result of incorrect or changed parameterization

As a result of incorrect or changed parameterization, machines can malfunction, which in turn can lead to injuries or death.

•Protect the parameterization (parameter assignments) against unauthorized access.

•Respond to possible malfunctions by applying suitable measures (e.g. EMERGENCY STOP or EMERGENCY OFF).

1.2 Industrial security

1.2Industrial security

Note

Industrial security

Siemens provides products and solutions with industrial security functions that support the secure operation of plants, solutions, machines, equipment and/or networks. They are important components in a holistic industrial security concept. With this in mind, Siemens’ products and solutions undergo continuous development. Siemens recommends strongly that you regularly check for product updates.

For the secure operation of Siemens products and solutions, it is necessary to take suitable preventive action (e.g. cell protection concept) and integrate each component into a holistic, state-of-the-art industrial security concept. Third-party products that may be in use should also be considered. For more information about industrial security, visit Hotspot-Text (http://www.siemens.com/industrialsecurity).

To stay informed about product updates as they occur, sign up for a product-specific newsletter. For more information, visit Hotspot-Text (http://support.automation.siemens.com).

WARNING

Danger as a result of unsafe operating states resulting from software manipulation

Software manipulation (e.g. by viruses, Trojan horses, malware, worms) can cause unsafe operating states to develop in your installation which can result in death, severe injuries and/or material damage.

•Keep the software up to date.

You will find relevant information and newsletters at this address (http://support.automation.siemens.com).

•Incorporate the automation and drive components into a holistic, state-of-the-art industrial security concept for the installation or machine.

You will find further information at this address (http://www.siemens.com/industrialsecurity).

•Make sure that you include all installed products into the holistic industrial security concept.

●Compact Operating Instructions in German and English

●The inverter contains open-source software (OSS). The OSS license terms are saved in the inverter.

Transferring license terms of the OSS code to a PC

Procedure

To transfer the OSS license terms from the inverter to a PC, proceed as follows:

1.Switch off the inverter power supply.

2.Insert an empty memory card into the card slot of the inverter. Also see Section:Overview of the interfaces (Page 8)

3.Switch on the inverter power supply.

4.When you have switched on the power supply, wait 30 seconds.

During this time, the inverter writes the "Read_OSS.ZIP" file onto the memory card.

5.Switch off the inverter power supply.

6.Remove the card from the inverter.

7.Use a card reader and load the file to a PC.

You have then transferred the OSS license terms from the inverter to a PC.
