Introduction
SINAMICS S120 solves complex drive tasks for a wide range of industrial applications
and is designed as a modular system. Users can select from many different harmonized
components and functions to create a solution that best meets their requirements.
SINAMICS S120 features Line and Motor Modules that cover a broad power range. They are
available in different formats: Booksize Modules up to 120kW and Chassis Modules for larger
power ranges. In several applications drives are required to be connected to a common DC bus,
which allows cost-saving energy balancing between braking and driving axes. Any combination
of modules within the existing families, e.g. Chassis Line Modules with any number of Chassis
Motor Modules or Booksize Line Modules with any number of Booksize Motor Modules is
already sufficiently qualified and described in the existing manuals.
The relevant documents can be accessed at following address:
https://support.industry.siemens.com/cs/ww/en/ps/13231/man?ml=en
Copyright  Siemens AG 2018 All rights reserved
This document describes the connection of Chassis Line and Motor Modules and Booksize
Motor Modules to one common DC bus. In the further text such a system may also be called
mixed installation or mixed system.
The existing manuals for the S120 system have to be observed as well.
Mixed installation of S120 Booksize and Chassis Modules according to this application
description is certified by UL (File.No. E192450 / Volume 5 /Section 23).
The document is intended for both panel builders and field assembly. Installations that follow
these instructions are UL listed and will not require procedure description in the industrial control
panel builder report (UL508A and CSA C22.2 No.14).
Some sections are marked as IEC requirements. These are not approved by UL.

Line Modules (Converter Section)
Table 1 shows all suitable Line Modules air cooled in Chassis format.
If even larger power is required, Chassis Line Modules of any type (Active Line Module, Smart
Line Module or Basic Line Module) can be connected in parallel. Only identical modules are
permitted for this operation. Maximum number is limited to 4 units in parallel. All Line Modules
have to be powered from the same source. Details on parallel connection can also be found in
the manual for Chassis Line Modules.
For proper and safe operation, line reactors in accordance with table 1 are required to be
installed with every Basic or Smart Line Chassis Module as shown in picture 1. Active Line
Modules are only permitted to be used together with Active Interface Modules. Line reactors and
Active Interface Modules are shown in picture 1.
Line Modules might be installed together with Line Connection Modules that are helpful for
easier installation of line side components and fuses, details in

List manual:
https://support.industry.siemens.com/cs/ww/en/view/56745894/en
Busbars connected to the Chassis Line Modules have to be
 Installed acc. to UL508A (internal wiring only, no field wiring)
 Protected against mechanical damage
Copyright  Siemens AG 2018 All rights reserved
Example for DC busbars: Siemens Busbar System 8US
Details about the Siemens busbar system and its components like connection modules,
supports, covers etc. can be found in Siemens Industry Online Support (SIOS)
https://support.industry.siemens.com/cs/products?search=8US%20busbar%20power%20distrib
ution%20system&lc=en-WW
The rated current of the busbars shall not be less than the rated DC current of the Line Module.
If Line Modules are connected in parallel, the rated current of the busbar shall not be lower than
the sum of the rated output currents of the Line Modules. The sum of the rated DC input
currents of all Motor Modules that are connected to the busbars and running at the same time
has to be considered as well. The ampacity of the busbars has to be calculated by the factor

Double-T Profile Part No.
8US1948-2AA00
nominal current
1400A
Busbar supports: 8US1943-3AA00
Maximum spacing of busbar supports: 800mm
For mechanical stability, all three profiles (busbars) have to be assembled. DC connection has
to be done with the outer profiles.
Once the installation is done with these components, a SCCR of 100kA for the whole system
can be achieved. SCCR values of Line and Motor Modules or additional components might limit
this to lower values.
Other components or busbars with higher or lower current rating might be used as well. In this
case, further UL investigation has to be done in the application.
To connect the Line Modules to the busbar system the feeder lug 8US1941-2AA04 shall be
used, which connects to busbars up to 32mm by 20mm. Together with this feeder lug, the cover
8US1922-1GC00 has to be used.

Table 5: Wire connections to the DC Tap Conductor Protection
As a protection against short circuit one of the following measures must be implemented:
 use wires suitable for enhanced protection
 maintain adequate clearance, using spacers, for example
 route the wires in separate cable ducts or conduits
The wires shall have a minimum temperature rating of 90°C and a minimum voltage rating of
600VAC.
4.1.2
DC Tap Conductor Protection
These protection fuses provide two functions:
1. to limit a fault current in case of a failure in the Motor Module
2. to separate the fault from the remaining devices connected to the common DC bus in
case of a failure, so the remaining drives may remain operational.

4.1 General
There has to be one DC fuse for each tap conductor, the positive and the negative DC bus.
Both fuses shall be identical i.e. shall have the same model number (means same
manufacturer, type & rating). Always after the fault and correcting the root cause of the
fault, both the fuses shall be replaced, even though only one of them has operated and opened
to clear the fault, and the other appears intact.
Only the DC fuses and fuse bases specified in table 6 in this manual shall be used.
Other fuses shall not be used. These fuses provide short circuit protection only, overload
protection is integrated into the power modules.
4.1.3
DC Tap Wires to the Motor Module
The wires shall have a minimum temperature rating of 90°C and a minimum voltage rating of
600VAC.
4.1.4
DC link adapters
Booksize Motor Modules have to be connected via DC link adapters. Cable lugs or the like shall
not be used. Different adapters are available to connect individual Motor Modules or groups of
Motor Modules.

4 Connection of Booksize Motor Modules
4.3
Connection of Booksize Motor Module groups
Booksize Motor Modules can be connected in groups combined on a separate part of the DC
bus. In this case the DC bus included in the modules is used for electrical connection.
There is no limitation regarding different types and number of motor modules that can be used
for this application
The rated DC current of the group is the sum of rated DC input currents of all motor modules
installed in the group and running at the same time. The conductors and DC bus fuses must be
selected according to the sum current. Table 7 shows the components to be installed based on
the sum of the DC current in the group. The row with the next higher current shall be used. The
sum current shall not exceed 200A. To connect the DC Tap Wires to a group of Booksize Motor
Modules, the DC link adapter for side connection (6SL3162-2BM01-0AA0) must be used.
The actual current rating of the internal DC link busbar of the individual Motor Modules must not
be exceeded.
