Configuration
Motor Modules in booksize format are factory-installed as "Booksize Cabinet Kits" in
Booksize Base Cabinets and delivered as a complete unit including cabinet-side connection
components.
Multiple Booksize Cabinet Kits can be installed in one Base Cabinet, depending on the
mounting width requirements, which in turn depend on the power. Each Motor Module is
connected separately to the DC busbar of the Cabinet Modules via a separate fuse switch
disconnector. The DC link rail integrated in the devices is not used. As a 24 V DC supply
buffered by the DC link is not possible with booksize, a dedicated SITOP is used to provide
the 24 V DC required for the Booksize Cabinet Kit.
Note
The configuration examples of the individual Motor Modules are used to illustrate the
positioning of the factory-fitted components. They show the maximum possible configuration
of the modules, which contain all options that can be ordered.
