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

On the line side, either a contactor or a circuit breaker is absolutely essential for the Smart Line Module. With the
selection of option L44 at the Line Connection Module these components are, harmonized with the Smart Line
Module, installed in the Line Connection Module.
7.2.6.2

DC link fuses

Every Smart Line Module is equipped with DC link fuses. These fuses are located in the power unit of each Smart
Line Module.
7.2.6.3

Parallel connections of Smart Line Modules

In order to achieve higher output power ratings, it is possible to connect up to four Smart Line Modules with the same
output power rating in parallel. As with other Line Modules, this parallel connection can be realized with separate Line
Connection Modules or one common Line Connection Module for two of the Smart Line Modules.
For this compact design of parallel configurations Smart Line Modules with "mirrored" power connections are
available, comparable to those of the Basic Line Modules. Smart Line Modules which are mounted to the left of the
Line Connection Module can be identified by the "C" at the last but one position of the order number, e.g. 6SL3730-
6TE41-1BC3.
A parallel connection with separate LCMs for each Smart Line Module can be realized with any units of the same
power rating.

Order numbers of the various air-cooled Smart Line Modules
Please note that parallel connections can only be made with Smart Line Modules of exactly the same power rating.
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. Furthermore, to balance the current of the parallel
configuration, a line reactor with a relative short-circuit voltage of 4 % is required for every Smart Line Module. This is
already integrated as standard.
Please also refer to the instructions regarding parallel connections in chapter "Fundamental Principles and System
Description", as well as to the guidance relating to the use of DRIVE-CLiQ cables and their installation in section
"Information about equipment handling / DRIVE-CLiQ wiring".
