General

SINAMICS S120 Cabinet Modules are a modular cabinet system comprising compact, type-tested and system-tested
components. SINAMICS S120 Cabinet Modules have been specially developed to facilitate the construction of
compact and reliable multi-motor systems in cabinet format.

SINAMICS S120 Cabinet Modules are available as air-cooled or liquid-cooled units.
The air-cooled SINAMICS S120 Cabinet Modules are based on the air-cooled SINAMICS S120 built-in units in
Chassis and Booksize format.
The liquid-cooled S120 Cabinet Modules are based on the SINAMICS S120 liquid-cooled built-in units in Chassis
format.
The Cabinet Modules have been developed according to the zone concept and thus offer the highest possible
standard of functional and operational reliability. EMC measures have been implemented and the systems design
ensures optimum air-flow guidance and cooling. Standardized design concepts have been implemented to achieve a
broad scope of applications and relative ease of servicing.
The individual Cabinet Modules are equipped with all necessary terminals and standardized connection elements to
ensure that they can be erected and installed quickly and easily and will be operationally reliable after installation.
This applies both to the electrical connections (power busbars, auxiliary power cables and signal cables) and to the
coolant piping for liquid-cooled Cabinet Modules. The Cabinet Modules are generally shipped in several transport
units in a ready-to-connect state and, thanks to their standardized connection elements, are perfectly prepared for
rapid assembly of the transport units on site.
The SINAMICS S120 Cabinet Modules described in this chapter have been specially designed for outstanding
flexibility and compact dimensions. With their type-tested and system-tested components, they are not only
functionally and operationally reliable, but also extremely durable. As a result, they are superior to individually
customized cabinet solutions, especially with respect to functional and operational reliability.
Note:
Not all of the components installed in SINAMICS S120 Cabinet Modules are available as separate system
components for SINAMICS S120 built-in units.
Standardized DC busbar
All SINAMICS S120 Cabinet Modules are equipped with a standardized DC busbar. This is used in air-cooled and
liquid-cooled Cabinet Modules. It is located near the top of the Cabinet Modules and is available in various cross-
sections that can be selected using options M80 to M87. Due to the DC busbar, SINAMICS S120 Cabinet Modules
are at least 2200 mm in height and are therefore 200 mm higher than the comparable SINAMICS G150 and S150
cabinet units for single drives. Depending on the degree of protection, the cabinet height can increase by 250 mm or
400 mm.
