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 be able to achieve higher output power ratings, it is possible to connect up to four Active Line Modules in
parallel. Each Active Line Module must be connected to its associated Active Interface Module. 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 Active Line Modules + Active Interface Modules.
For parallel connection at one common Line Connection Module, Active Line Modules with their associated Active
Interface Modules can, like Basic Line Modules and Smart Line Modules, be connected to the right and left of the
Line Connection Module. The Active Line Module / Active Interface Module mounted to the left of the Line Connection
Module is equipped with "mirrored" power connections (order number with the "C" at the last but one position e.g.
6SL3730-7Tx41.-.BC0). The Active Interface Module is turned to the Line Connection Module. This allows a simpler
installation on site if the Active Infeed is ordered separately from the LCM / not within a transport unit. Active Line
Modules designed for mounting to the right of the Line Connection Module do not have any special order numbers.
A parallel connection with separate LCMs can be realized with any units of the same power rating.
