Technical requirements

The hardware configuration of the parallel connection depends on the technical specifications.
These specifications are binding and must be adhered to.
Note
No UL certification
The parallel connection of the SINAMICS S120 Motor Modules Booksize in accordance with
this application description is not UL-certified.
Note
EMC Directive
The system integrator is responsible for adhering to the EMC Directive when using the parallel
connection of Motor Modules Booksize.
Note
Power supply of the Motor Modules Booksize
Motor Modules connected in parallel require a corresponding infeed power.
If the power is supplied via the parallel connection of SINAMICS Active Line Modules, you can
find further information in the application description "Active Line Modules Booksize, parallel
connection (https://support.industry.siemens.com/cs/ww/en/view/109759667)".
Symmetrical layout
Input side
The voltage source must be identical for the Motor Modules Booksize that are connected in
parallel.
When using the DC link bars of the Motor Modules Booksize, the current load must not exceed
the maximum of 200 A.
These requirements necessitate the symmetrical setup of the modules:
● Symmetrical arrangement of the two Motor Modules Booksize connected in parallel
● The Active Line Modules infeed modules are positioned based on the maximum current
carrying capacity of the DC link bars.
You can find further information in the application description "Active Line Modules
Booksize, parallel connection
109759667)".
