Supply of two Basic Line Modules via two separate Line Connection Modules (12-pulse Infeed)
A double-tier converter transformer must be selected in order to obtain a 12-pulse Infeed which has lower harmonic
effects on the supply. The two secondary windings are mutually phase-shifted by 30 el (vector group e.g. Dy5Dd0 or
Dy11Dd0).
This arrangement then supplies one Basic Line Module via one LCM in each case. The Basic Line Modules are
protected by the fuses or circuit breakers (at I >800 A) in the LCMs, i.e. BLMs with supplementary line fuses are not
required (each module is version 6SL3730-1T□□□-□AA0).
Supply of two Active Infeeds via a common Line Connection Module
To obtain a higher Infeed capacity with Active Infeeds, these modules can be connected in parallel.
A compact arrangement can be achieved by supplying the Active Infeeds from a common line supply. The
combinations of Active Line Modules and Active Interface Modules are erected to the left and right of the Line
Connection Module. Derating of 5 % must be applied to parallel connections to compensate for current imbalances.
As regards the cabinet sequence, the Motor Modules with high output ratings should be placed closest to the Infeed
and the others arranged in descending order of output rating. This configuration is not absolutely essential, but allows
the DC link busbars to be arranged more efficiently and is therefore cheaper.

Door opening angle

The doors on Cabinet Modules are 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 door
o
with degree of protection IP23/IP43/IP54
o
with option L37 (DC-Switch)
