DC link fuses

SINAMICS power units in Booksize format feature integrated DC link fuses. These are not replaceable, however, but
merely protect against hazards. For this reason, Booksize cabinets are fitted with switch-disconnectors with
integrated fuses which are designed as standard to make the connection to the DC link busbar. The fuses are chosen
according to selective criteria to ensure that the fuse in the switch-disconnector blows first in the event of a fault in the
DC circuit.

Planning recommendations, special features

An equipping of the base Cabinets can be variably carried out with the Cabinet Kits without predefined mounting
sequence or size assignment. The width of a Base Cabinet available for installing Cabinet Kits is calculated on the
basis of a cabinet width of – 200 mm. The useful mounting widths available are therefore as follows:
Order number of
Booksize Base Cabinet
6SL3720-1TX38-0AA0
6SL3720-1TX41-2AA0
Assignment between cabinet width and useful 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 zoning
concept. The components are also likewise positioned in such a way that diagnostic elements are always freely
accessible.
For an easy connection of external cables, Booksize cabinets are equipped with the customer terminal block –X55 as
well as the customer terminal module –A55 in combination with a Control Unit (option K90/ K91). For further
information, please refer to the sections on these specific components in this chapter.
