Target group
This documentation is intended for machine manufacturers, commissioning engineers, and
service personnel who use the SINAMICS drive system.
Benefits
This manual provides all of the information, procedures and operator actions required for the
particular usage phase.
Standard scope
The scope of the functionality described in this document can differ from that of the drive
system that is actually supplied.
●Other functions not described in this documentation might be able to be executed in the
drive system. However, no claim can be made regarding the availability of these functions
when the equipment is first supplied or in the event of service.
●The documentation can also contain descriptions of functions that are not available in a
particular product version of the drive system. The functionality of the supplied drive
system should only be taken from the ordering documentation.
●Extensions or changes made by the machine manufacturer must be documented by the
machine manufacturer.
For reasons of clarity, this documentation does not contain all of the detailed information on
all of the product types, and cannot take into consideration every conceivable type of
installation, operation and service/maintenance.

Preface
SINAMICS S120 Combi
Manual, 11/2017, 6SL3097-4AV00-0BP7 9
Not relevant standards
China Compulsory Certification
SINAMICS S devices do not fall in the area of validity of the China Compulsory Certification
(CCC).
EMC limit values in South Korea
The EMC limit values to be observed for Korea correspond to the limit values of the EMC
product standard for variable-speed electric drives EN 61800-3 of category C2 or the limit
value class A, Group 1 to KN11. By implementing appropriate additional measures, the limit
values according to category C2 or limit value class A, Group 1, are observed. Further,
additional measures may be required, such as using an additional radio interference
suppression filter (EMC filter).
The measures for EMC-compliant design of the system are described in detail in this manual
respectively in the EMC Installation Guideline Configuration Manual.
The final statement regarding compliance with the standard is given by the respective label
attached to the individual unit.
Ensuring reliable operation
The manual describes a desired state which, if maintained, ensures the required level of
operational reliability and compliance with EMC limit values.
Should there be any deviation from the requirements in the manual, appropriate actions (e.g.
measurements) must be taken to check/prove that the required level of operational reliability
and compliance with EMC limit values are ensured.
Spare parts
Spare parts are available on the Internet at the following address
(https://www.automation.siemens.com/sow?sap-language=EN).
Product maintenance
The components are subject to continuous further development within the scope of product
maintenance (improvements to robustness, discontinuations of components, etc).
These further developments are "spare parts-compatible" and do not change the article
number.
In the scope of such spare parts-compatible further developments, connector/connection
positions are sometimes changed slightly. This does not cause any problems with proper
use of the components. Please take this fact into consideration in special installation
situations (e.g. allow sufficient clearance for the cable length).

1.1
General safety instructions
WARNING
Electric shock and danger to life due to other energy sources
Touching live components can result in death or severe injury.
•Only work on electrical devices when you are qualified for this job.
•Always observe the country-specific safety rules.
Generally, the following six steps apply when establishing safety:
1. Prepare for disconnection. Notify all those who will be affected by the procedure.
2. Isolate the drive system from the power supply and take measures to prevent it being
switched back on again.
3. Wait until the discharge time specified on the warning labels has elapsed.
4. Check that there is no voltage between any of the power connections, and between any
of the power connections and the protective conductor connection.
5. Check whether the existing auxiliary supply circuits are de-energized.
6. Ensure that the motors cannot move.
7. Identify all other dangerous energy sources, e.g. compressed air, hydraulic systems, or
water. Switch the energy sources to a safe state.
8. Check that the correct drive system is completely locked.
After you have completed the work, restore the operational readiness in the inverse
sequence.
WARNING
Electric shock due to connection to an unsuitable power supply
When equipment is connected to an unsuitable power supply, exposed components may
carry a hazardous voltage that might result in serious injury or death.
•Only use power supplies that provide SELV (Safety Extra Low Voltage) or PELV-
(Protective Extra Low Voltage) output voltages for all connections and terminals of the
electronics modules.

20 Manual, 11/2017, 6SL3097-4AV00-0BP7
WARNING
Electric shock due to equipment damage
Improper handling may cause damage to equipment. For damaged devices, hazardous
voltages can be present at the enclosure or at exposed components; if touched, this can
result in death or severe injury.
•Ensure compliance with the limit values specified in the technical data during transport,
storage and operation.
•Do not use any damaged devices.
WARNING
Electric shock due to unconnected cable shield
Hazardous touch voltages can occur through capacitive cross-coupling due to unconnected
cable shields.
•As a minimum, connect cable shields and the conductors of power cables that are not
used (e.g. brake cores) at one end at the grounded housing potential.
WARNING
Electric shock if there is no ground connection
For missing or incorrectly implemented protective conductor connection for devices with
protection class I, high voltages can be present at open, exposed parts, which when
touched, can result in death or severe injury.
•Ground the device in compliance with the applicable regulations.
WARNING
Arcing when a plug connection is opened during operation
Opening a plug connection when a system is operation can result in arcing that may cause
serious injury or death.
•Only open plug connections when the equipment is in a voltage-free state, unless it has
been explicitly stated that they can be opened in operation.
WARNING
Electric shock due to residual charges in power components
Because of the capacitors, a hazardous voltage is present for up to 5 minutes after the
power supply has been switched off. Contact with live parts can result in death or serious
injury.
•Wait for 5 minutes before you check that the unit really is in a no-voltage condition and
start work.
