DC Link fuses

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

Parallel connections of Active Line Modules + Active Interface Modules

In order to achieve higher output powers, it is possible to connect up to four Active Line Modules of identical output
rating in parallel. Each Active Line Module is assigned to its own Active Interface Module. In a similar manner to other
Line Modules, the parallel connection can be configured with a separate Line Connection Module for each Active Line
Module, or with LCMs to which two Active Line Modules with matching Active Interface Modules are connected.
For parallel connection on a common Line Connection Module, there are variants of Active Line Module available
which, in a similar manner to Basic Line Modules and Smart Line Modules, can be arranged on the right or left of the
Line Connection Module. This configuration represents an extremely compact Infeed arrangement. The Active Line
Module positioned on the left of the Line Connection Module features "mirror-image" power connections, identifiable
by a "C" in the last but one position in the order number, e.g.: 6SL3730-7T_41-_BC3. In contrast to the Active Line
Module mounted on the right, the Active Interface Module for the Active Line Module on the left is transposed so that
it is directly adjacent to the Line Connection Module. This makes on-site assembly easier if the Active Line Module
incl. Active Interface Module has been ordered separately from the LCM and are not shipped in a single transport
unit. Active Line Modules for positioning on the right of the Line Connection Module do not have a special order
number.
Parallel connections with a separate LCM for each Active Line Module can be implemented with units with any output
power rating.
