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

Fundamental safety instructions
1.1
General safety instructions
WARNING
Danger to life if the safety instructions and residual risks are not observed
If the safety instructions and residual risks in the associated hardware documentation are
not observed, 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, 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 only represent one component of such a
concept.
The customer is responsible for preventing unautho
rized access to its plants, systems,
machines and networks. Systems, machines and components should only be connected to
the enterprise network or the internet if and to the extent necessary and with appropriate
security measures (e.g. use of firewalls and
network segmentation) in place.
Additionally, Siemens’ guidance on appropriate security measures should be taken into
account. For more information about industrial security, please visit:
Industrial security (
http://www.siemens.com/industrialsecurity).
Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends to apply product updates as soon as available and to
always use the latest product versions. Use of product versions that are no longer supported,
and failure to apply latest updates may increase customer’s exposure to cyber threats.

WARNING
Danger to life as a result of unsafe operating states resulting from software manipulation
Software manipulations (e.g. viruses, trojans, malware or worms) can cause unsafe
operating states in your system that may lead to death, serious injury, and property
damage.
•Keep the software up to date.
•Incorporate the automation and drive components into a holistic, state-of-the-art
industrial security concept for the installation or machine.
•Make sure that you include all installed products into the holistic industrial security
concept.
•Protect files stored on exchangeable storage media from malicious software by with
suitable protection measures, e.g. virus scanners.

●Compact Operating Instructions in German and English
●The inverter contains open-source software (OSS). The OSS license terms are saved in
the inverter.
Transferring OSS license terms to a PC
Procedure
To transfer OSS license terms 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.
Overview of the interfaces (Page 9)
3. Switch on the inverter power supply.
4. The inverter writes file "Read_OSS.ZIP" to the memory card within approximately
30 seconds.
5. Switch off the inverter power supply.
6. Withdraw the memory card from the inverter.
7. Insert the memory card into the card reader of a PC.
8. Please read the license terms.
You have transferred the OSS license terms to a PC.

Each Power Module has an appropriate holder for the Control Unit and a release
mechanism.
Inserting the Control Unit
Proceed as follows to plug the Control
Unit onto a Power Module:
1.
Place the two catches of the
Control Unit in the matching
grooves of the Power Module.
2.
Press the Control Unit onto the
Power Module until you hear that it
latches.
You have now plugged the Control
Unit onto the Power Module.
Removing the Control Unit
Remove the Control Unit from the Power Module by pressing the release mechanism.

Special features for the PM230 Power Module IP55, FSA … FSC
To insert or detach the Control Unit, you must
release eight
or ten fixing screws of the cover
and then remove the cover.
The Power Module release mechanism is
shown in the diagram.
Attach the cover again before you commission
the inverter. Do not damage the seal of the
cover when attaching it.
Adapter for operating a PM230 IP55 Power Module
For operating the Control Unit with a PM230 IP55 Power Module, FSA … FSC, an adapter is
required between the Control Unit and operator panel (BOP-2 or IOP).
The adapter, which is included in the scope of delivery of the Power Module, is too short for
the CU240E-2 Control Unit. The matching adapter for the CU240E-2 Control Unit can be
ordered through the KnorrTec company.
