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
personnel qualified
for the specific

1.1
Responsibility of the user for system configuration and functionality
The SIRIUS 3RM1 motor starters described here have been developed to carry out
switching functions as part of a plant or machine.
The 3RM1 motor starters are available as direct-on-line starters in Standard design without
safety-related shutdown (3RM10) and in Failsafe design with safety-related shutdown
(3RM11 Failsafe), and also as reversing starters without safety-related shutdown (3RM12)
and in Failsafe design with safety-related shutdown (3RM13 Failsafe).
The following must be noted when using 3RM11 Failsafe/3RM13 Failsafe safety-related
motor starters:
A complete safety system consists of sensors, evaluation units, signaling devices and
methods for safety-related shutdown.
The manufacturer is responsible for ensuring safe overall functioning of a plant or machine

A DataMatrix code is lasered onto the lower terminal cover of all devices of this series.
DataMatrix codes are standardized in ISO/IEC 16022. The DataMatrix codes on Siemens
devices use ECC200 coding.
The following device information is encoded in the DataMatrix codes as a bit stream:
●Article number
●Serial number
This information is stored in the following format in the DataMatrix code:
1P
Article number
+
S
Serial number
Data identifier Net content Separator Data identifier Net content
Note
The information content is displayed without spaces.
This machine-readable information simplifies and accelerates handling of the respective
devices.
As well as fast access to the serial numbers of the respective devices for unique
identification, the DataMatrix codes simplify communication with Siemens Technical Support.
SIEMENS Industry Support App
DataMatrix codes primarily enable extremely fast and convenient access to all device-
specific information relating to an article number in the SIEMENS Service&Support Portal
(https://support.industry.siemens.com/cs/ww/en/), such as operating instructions, manuals,
