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

Fundamental safety instructions
1.1
General 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).

Industrial 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 eac
h 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.

Module so that it audibly snaps into place.
The Power Module and the Control Unit are now connected with one another.
To remove the Control Unit, press on the release button on the Power Module and withdraw
the Control Unit.
Permissible Power Modules
You may operate the Control Unit with the following Power Modules:
●PM240

Different reference potentials:
The terminals labelled "GND" are connected internally.
"GND" and "GND IN" are not connected internally.
Figure 3-1 Interconnection example of the digital inputs with external 24 V power supply
Interconnecting the analog inputs (terminals 3, 4 and 10, 11)
For the analog inputs, you may use the internal 10 V supply (example: terminals 1 … 4, 13)
or an external supply (example: terminals 10, 11).
If you use the internal 10 V supply, you must connect AI 0- or AI 1- to GND.
