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 indust
rial 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 continu
ous 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 comp
onent 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 this address
(
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 this address (
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.

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.
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.

3.3
Terminal strips behind the upper front door
All terminals with reference potential "GND" are connected with one another in the inverter.
Terminals 31, 32
Connection of the optional 24 V supply has the following advantages:
•The Control Unit remains in operation after disconnection of the Power Module from the line sup-
ply. The Control Unit thus maintains the fieldbus communication, for example.
•You can use terminals 51 … 54 as digital outputs.
Power supplies in conformance with SELV (Safety Extra Low Voltage) or PELV (Protective Extra Low
Voltage) are permissible.
If you use a common external power supply for terminals 31, 32 and the digital inputs, you must con-
nect GND and the reference potential of the digital input ("DI COM1/2/3") with each other.
Terminals 3, 4 and 10, 11: You may use the internal 10 V supply or an external power supply for the analog inputs. For
an internal 10 V supply: Connect AI 0, respectively AI 1- with GND.

Wiring the terminal strip in compliance with EMC
1. 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.
Further information is provided in the Internet:
EMC installation guideline
(http://support.automation.siemens.com/WW/view/en/60612658)
2. Use the shield connection plate (order number 6SL3264-1EA00-0LA0) of the Control Unit
as strain relief.

Operator panels
Operator panel
An operator panel is used to commission, troubleshoot and control the inverter, as well as to
back up and transfer the inverter settings.
The Intelligent Operator Panel (IOP) is available for snapping on to the Control Unit or as
handheld with a connection cable to the Control Unit. The graphics-capable plain text display
of the IOP enables intuitive operation and diagnostics of the inverter.
The IOP is available in two versions:
●With European languages
●With Chinese, English and German
Additional information about the compatibility of the IOP and Control Units is available in the
Internet:
