Dc Link Fuses; Parallel Connections Of Basic Line Modules - Siemens SINAMICS G130 Engineering Manual

DC link fuses

The Basic Line Modules do not have DC link fuses as standard.
If fuses are required, they can be ordered with option N52. The fuses are mounted on the connecting rail to the DC
busbar in the cabinet and not in the power unit itself.

Parallel connections of Basic Line Modules

Frame sizes GB/ GD are designed as a special variant which is also suitable for operation in parallel connections on
one Line Connection Module. Line-side fuses need to be provided to selectively protect the individual Basic Line
Modules in a parallel connection. The standard cabinet needs to be widened by 200 mm for this purpose. These units
can be identified by the "B" in the third to last position of the order number (example: 6SL3730-1T.41-.AA0 is the
variant without line-side fuses, 6SL3730-1T.41-.BA0 resp. 6SL3730-1T.41-.BC0 is the variant prepared for parallel
connection).
These units are installed to the right and left of the Line Connection Module. The design of the two variants is
identical. The Basic Line Module for mounting on the left of the LCM differs only in that it is provided with additional
connecting rails. The distinction between the left and right variants can be identified by the last but one position in the
order number, i.e. an "A" stands for the right-hand variant and a "C" for the left-hand variant.

Order number assignment for BLMs
Please note that only Basic Line Modules with exactly the same output power rating can be connected in parallel.
The potential for imbalances in current distribution means that current derating of 7.5 % must be applied and this
must be taken into account when the modules are dimensioned.
