7.2.9 Booksize Base Cabinet / Booksize Cabinet Kits
7.2.9.1 Design
Motor Modules in Booksize format are installed as Booksize Cabinet Kits into Booksize Base Cabinets in the factory
and supplied as a complete unit together with inside the cabinet installed terminals for motor connection. All Booksize
Motor Modules are available in the version with internal air cooling and varnished electronic boards.
7.2.9.2 Booksize Base Cabinet
The Booksize Base Cabinet is the basis for a complete cabinet. This provides all the assembly plates required to
accommodate the Booksize Cabinet Kits.
Booksize Base Cabinets are available in two standard cabinet widths, i.e. 800 mm and 1200 mm. In addition to the
assembly plates, the cabinet also includes the PE bar and the auxiliary voltage supply system.
7.2.9.3 Booksize Cabinet Kits
Booksize Cabinet Kits are made to support an easy planning and equipping by using a slot concept. A slot (Booksize
Cabinet Kit) has a specified cabinet width within which all the components are arranged that are required to operate a
Booksize format SINAMICS S120 drive. The number of slots within a Base Cabinet is determined by the available
width of the cabinet. Depending on the mounting width required for the relevant output power, the number of
Booksize Cabinet Kits which can be mounted in a Base Cabinet varies.

The basic version of the Booksize Cabinet Kit
comprises the following components:
· Motor Module in Booksize format
· Fuse-switch
disconnector for each Motor Module
installed
· Customer terminal block X55.1 or X55.2
located in
the terminal area of the Booksize Base Cabinet
· Shield connecting plate
·
Complete electrical connection to the Base Cabinet
interfaces
Each Booksize Cabinet Kit i
s connected to the DC
busbar of the Cabinet Mod
ule separately via its own
fuse-switch disconnector. The DC rail
integrated in the
Booksize power units is not used to lo
op through the
DC link voltage.
The optional DC interface
consists of a contactor
assembly
(see section "Option L37" in chapter
"Description of Options for Cabinet Units") which is
very easy to replace thanks to its pluggable interfaces.
When the optional CU320-2
DP (option K90) or
CU320-2
PN (option K95) Control Unit is installed, the
cable
termination area of the cabinet also includes the
customer terminal block –X55. A DRIVE-
CLiQ
connection to the power unit of the Cabinet Kit is
made at the factory.
Output reactors or motor reactors
can be also
installed within a Cabinet Kit as an option.
When
reactors are used, a separate motor connecting
terminal is provided in the terminal
area of the cabinet.
For information about output reactors
or motor
reactors, please
refer to chapter "Description of
Options for Cabinet Units”, section "Option L08 / L09".
