DC link fuses

SINAMICS power units in Booksize format are equipped with integral DC link fuses in the positive path. These are
not replaceable, however, they protect against hazards. For this reason, Booksize Cabinet Kits are fitted with fuse-
switch disconnectors with integral fuses in the positive and negative paths which make the standardized connection
to the DC busbar of the Cabinet Module. The fuses are chosen according to selective criteria to ensure that the fuses
in the switch disconnector typically trip first in response to a fault in the Booksize unit.

Planning recommendations, special features

Equipping of the Base Cabinets with Booksize Cabinet Kits can be variably carried out without predefined mounting
sequence or size assignment. The width of a Base Cabinet available for installing Cabinet Kits is calculated on the
basis of the cabinet width minus 200 mm. The utilizable mounting widths available are therefore as follows:
Order number of
Booksize Base Cabinet
6SL3720-1TX38-0AA3
6SL3720-1TX41-2AA3
Assignment between cabinet width and utilizable mounting width
Booksize Cabinet Kits can only be ordered in combination with at least one Booksize Base Cabinet. It is not possible
to order Booksize Cabinet Kits separately.
The components are arranged within a Cabinet Kit and within the Base Cabinet itself according to the zone concept.
The components are also positioned in such a way that diagnostic elements are always freely accessible.
For easy connection of external cables, the Booksize Cabinet Kits are equipped with the customer terminal blocks
–X55.1 and/or –X55.2 as well as with the customer terminal block –X55 if a CU320-2 DP (option K90) or CU320-2
PN (option K95) Control Unit is installed. For further information, please refer to the sections with corresponding
headings in this chapter or to chapter "Description of Options".
