Supply of two Basic Line Modules via two separate Line Connection Modules (12-pulse Infeed)
In order to implement a 12-pulse Infeed which reduces harmonic effects on the supply system, a three-winding
transformer (double-tier design if possible) must be selected. The two secondary windings are mutually phase-shifted
by 30 el (Dy5d0 or Dy11d0 are suitable vector groups).
In this arrangement, each Basic Line Module is supplied by a separate Line Connection Module. Each Basic Line
Module is protected by the fuses or circuit breakers (with I>800 A) in the relevant LCM, , i.e. no BLMs with additional
line fuses are required (version 6SL3730-1T_ _ _-_AA3 in each case).
Supply of two Active Infeeds via a common Line Connection Module
In order to obtain a higher Infeed capacity, Active Infeeds can also be connected in parallel. A current derating factor
of 5 % must be applied due to the possibility of current imbalances resulting from the parallel connection.
A symmetrical, compact arrangement of the Active Infeeds can be achieved with a single Line Connection Module.
The combinations of Active Line Module and Active Interface Module are installed on the left and on the right of the
Line Connection Module. The standard version is used for the combination on the right of the Line Connection
Module. A mirror-image version is available for the combination on the left.
As regards the cabinet sequence, the Motor Modules with the highest output ratings should be placed next to the
Active Infeed and the others arranged in descending order of output rating. This arrangement is not absolutely
essential, but allows better dimensioning of the DC busbars and thus helps to cut costs. For further information,
please refer to section "SINAMICS inverters or Motor Modules" in chapter "Fundamental Principles and System
Description".

Door opening angle

The doors on Cabinet Modules have the same width as the cabinets themselves. Cabinets up to a width of 600 mm
have a single door which is hinged on the right-hand side. Wider cabinets have double doors.
The following information is important, for example, in the planning of emergency exit routes:
·
Maximum door width:
·
Maximum door opening angle:
With degree of protection IP20 / IP21 without options in the cabinet doors
§
§ With degree of protection IP23 / IP43 / IP54 with ventilation openings
in the cabinet doors
§ With option L37 (DC breaker)
