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.

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.

Industrial security
Note
Industrial security
Siemens provides products and solutions with industrial security functi
ons 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. Sie
mens 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 holisti
c,
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

●Compact Operating Instructions in German and English
●The inverter contains open-source software (OSS). The OSS license terms are saved in
the inverter.
Reading the OSS license terms
The inverter contains open-source software (OSS). OSS comprises open source text and
satisfies special license terms. If you wish to read the license terms, you must transfer them
from the inverter 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. See also 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. Withdraw the memory 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, and you can now
read the license terms.

Wiring the terminal strip in compliance with EMC
●If you use shielded cables, then you must connect the shield to the mounting plate of the
control cabinet or with the shield support of the inverter through a good electrical
connection and a large surface area.
●Use the shield connection plate of the Control Unit as shield support and strain relief.

Terminal strips on CU240B-2 Control Units
Terminal strips with wiring example
All terminals labelled with reference potential "GND" are connected internally in the inverter.
Reference potential "DI COM" is electrically isolated from "GND".
→ If, as shown above, the 24 V supply from terminal 9 is used to supply the digital inputs, then you
must connect "GND" to "DI COM".
Terminals 31, 32
Reference potential "GND IN" is electrically isolated from "GND". When an optional 24 V power supply
is connected at terminals 31, 32, even when the Power Module is disconnected from the line supply,
the Control Unit remains in operation. The Control Unit thus maintains the fieldbus communication, for
example.
→ at terminals 31, 32, only connect a power supply that is in accordance with SELV (Safety Extra Low
Voltage) or PELV (Protective Extra Low Voltage).
→ if you use a common external power supply for terminals 31, 32 and the digital inputs, you must
connect "GND" to "GND IN".
Terminals 3, 4: You may use the internal 10V power supply or an external power supply for the analog input.
→ If you use the internal 10 V power supply, you must connect AI 0- to GND.
