2.1  General safety information 
Safety and commissioning information for converter-fed low-voltage three-phase motors  
 
DANGER 
 
All activities associated with transporting, connecting, commissioning, and maintaining the 
motors must be carried out by properly trained, responsible personnel (DIN EN 50110-1; 
note IEC 60364). 
Failure to follow proper procedures may result in injury or material damage. 
 
Special versions and construction variants may differ with respect to certain technical 
aspects. If in doubt, you are strongly advised to contact the manufacturer, specifying the type 
designation and serial number (see rating plate), or arrange for any maintenance work to be 
carried out by the SIEMENS Service Center. 
Systems and machines with converter-fed low-voltage three-phase motors must fulfill the 
protective requirements of the EMC Directive. 
The machine manufacturer is responsible for ensuring that installation is carried out properly. 
The signal and power cables to the motor must be shielded. 
The information provided by the converter manufacturer regarding EMC-compliant 
installation must be observed. 
Proper usage 
These motors are designed for use in industrial or commercial systems. They comply with 
the EN 60034-1 standards and the relevant associated sections. 
 
WARNING 
 
It is forbidden to install them in hazardous areas unless they are explicitly designed for this. 
 
If more stringent requirements are necessary in special cases (e.g. shock-hazard protection 
in non-commercial applications where children are likely to be present), the customer must 
implement the relevant measures to ensure that these requirements are fulfilled. 
Any alternative requirements specified on the rating plate must be taken into account. The 
on-site conditions must comply with the rating plate specifications.  
The motors are designed for use in sheltered areas under normal climatic conditions, such 
as those found in production halls.
