Motor Modules booksize format are installed in the factory as Booksize Cabinet Kits in Booksize Base Cabinets. This complete unit contains all of the components necessary for operation.

Each Motor Module is connected separately to the DC busbar of the SINAMICS S120 Cabinet Module via a separate fuse switch disconnector with integrated fuses. The DC connecting busbar integrated in the units is not used.

The basic version of the Booksize Cabinet Kit comprises the following components:

• Motor Module, booksize format
• Fuse switch disconnector for each Motor Module installed
• Customer interface -X55.1 located in the connection area of the Booksize Base Cabinet
• Shield connection plate
• Complete electrical connection to the Booksize Base Cabinet interfaces

Whereas Single Motor Modules have one inverter connection, Double Motor Modules combine two inverters in a single module. For each Double Motor Module that is installed in a Booksize Cabinet Kit, the customer interface, the motor connection and in some cases also options for separate control, are provided twice and shown in the option selection table.

The Booksize Base Cabinets can be operated up to and including IP54 degree of protection without additional temperature derating. However, some values need to be taken into account that differ from those of the chassis format. Derating data, see the System overview > Characteristic curves.
