Erection Of Cabinets; Examples Of Cabinet Module Arrangements - Siemens SINAMICS G130 Engineering Manual

SINAMICS S120 Cabinet Modules
Engineering Information
CLiQ wiring (see subsection "DRIVE-CLiQ" of the chapter "SINAMICS S120, General Information about Built-in and
Cabinet Units").
The additional cabling required is calculated as follows: 1.5 m + 0.4 m cabinet width + 1.4 m = 3.3 m. A pre-
assembled, 4 m long cable is recommended for this purpose: 6FX2002-1DC00-1AE0
Inter-cabinet DRIVE-CLiQ connecting cables can also be fitted in the factory on request. The order-specific
Integration Engineering (order number 6SL3780-0Ax00-0AA0) can, for example, be used for this purpose. For further
details, please ask your Siemens contact.

Erection of cabinets

The standard erection sequence for Cabinet Modules is from the left, starting with the Line Connection Modules,
followed by the Line Modules and ending with the Motor Modules on the far right.
To make allowance for the DC link busbar design, the Motor Modules should be arranged in decreasing order of
output rating, i.e. with the highest output at the Infeed and the lowest on the right or outside.
Configurations with parallel-connected Infeeds for inceasing the output power should be arranged as a symmetrical,
mirror image. In this instance, the Line Connection Module is positioned in the center of the cabinet group with the
two Line Modules. The Motor Modules are then arranged on the left and right of the Infeed units (see configuration
examples below).
Side panels (option L26 or L27) must be provided at both ends of the group to provide the requisite degree of
protection.

Examples of Cabinet Module arrangements

Supply of two Basic Line Modules via a common Line Connection Module (6-pulse infeed)
In the case of parallel connections of Basic Line Modules supplied by a common Line Connection Module, a derating
factor of 7.5 % must be applied due to the possibility of current imbalances.
In this case Basic Line Modules with mirror-image configuration must be selected, version 6SL3730-1T□41-□BA0 for
erection to the right of the LCM and 6SL3730-1T□41-□BC0 for erection to the left of the LCM must be selected for
such applications.
These module versions include integrated line-side fuses that are needed because the circuit breaker in the LCM is
not capable of providing selective protection for the Basic Line Modules. They are therefore 200 mm wider in each
case than version 6SL3730-1T□□□-□AA0.
