The respective slot is located at the top of the Control Unit.
    There is also a large number of components available for expanding the system, e.g. line-side power components, DC link components, load-side power components and supplementary system components.

Line-side power components

The following line-side power components are available for SINAMICS G120 inverter chassis units:
- Line filters - The PM240 Power Module complies with a higher radio interference class with one of the additional line filters.
- Line reactors ã- A line reactor is needed for high system fault levels, partly to protect the actual inverter against excessive harmonic currents,and thus against overload, and partly to limit the line harmonic distortions to the permitted values.

     Recommended line components
This is a recommendation for further line-side components, such as fuses and circuit-breakers (line-side components must be dimensioned in accordance with IEC standards).

DC link components
     The following DC link components are available for SINAMICS G120 inverter chassis units:

     Output reactors reduce the voltage loading on the motor windings.
     At the same time, the capacitive charge/discharge currents, which place an additional load on the power section when long motor cables are used, are reduced. LC filter and sinusoidal filter (available soon) The LC filter/sinusoidal filter limits the rate of rise of voltage and the capacitive charge/discharge currents which usually occur with inverter operation. It is therefore not necessary to use an output reactor.

SINAMICS G120
Inverter chassis units - PM240 Power Modules
 

     PM240 Power Modules feature an integrated brake chopper to which an external braking resistor can be connected via terminals DCP/R1 and R2 (see DC link components). The DC link capacitance of the DC link is such that the PM240 Power Module provides sufficient control range for the DC link voltage and is easily capable of handling applications such as kinetic buffering (maintenance of DC link voltage through regenerative feedback to DC link of kinetic energy produced by the load) or controlled, safe deceleration after a power failure using kinetic energy produced by the load. Furthermore, several PM240 Power Modules can be electrically coupled by this method.
     The PM240 Power Module is also designed for safety-sensitive applications. In conjunction with a Safety Control Unit, the drive can be turned into a Safety Integrated Drive (see Control Units). The permissible cable lengths between converter and motor are limited depending on cable type. Longer cables can be used if
output reactors are connected (see load-side power components). Line reactors are available for minimization of line harmonic distortions (see line-side power components).

SINAMICS G120
Inverter chassis units - Line Filters

Overview

     The PM240 Power Module complies with a higher radio interference class with one additional line filter. Frame size FSA of the PM240 Power Module is only available without integrated line filter of class A. A base filter for compliance with class A and another for compliance with class B are therefore available. Frame sizes FSB and FSC of the PM240 Power Module are available both with and without integrated line filter of class A. For compliance with class B, PM240 Power Modules with integrated line filter of class A must be fitted additionally with a base filter of class B.

SINAMICS G120
Inverter chassis units - Line Reactors

Overview

     A line reactor is needed for high system fault levels, partly to protect the actual inverter against excessive harmonic currents, and thus against overload, and partly to limit the line harmonic distortions to the permitted values.

Integration

     The line reactors for PM240 Power Modules of frame sizes FSA to FSE are designed as base components. The line reactor is attached to the mounting surface and the Power Module is mounted compactly on the line reactor. The cables to the Power Modules are already connected at the line reactor. The line reactor is connected to the line supply through terminals.

SINAMICS G120
Inverter chassis units - Recommended line components

Overview

     The following table lists recommendations for further line-side components, such as fuses and circuit-breakers (line-side components dimensioned in accordance with IEC standards). The specified circuit-breakers are UL-certified. Fuses of type 3NA3 are recommended for European countries. The 3NE1 fuses are
UL-compliant (corresponds to U). Further information on the listed fuses and circuit-breakers can be found in Catalogs LV 1 and LV 1 T.

SINAMICS G120
Inverter chassis units - Braking resistors

Overview

     Excess power in the DC link is dissipated via the braking resistor. The braking resistors are intended for use with PM240 Power Modules which feature an integrated brake chopper, but cannot regenerate energy to the supply system. For regenerative operation, e.g. the braking of a rotating mass with high moment of
inertia, a braking resistor must be connected to convert the resulting energy into heat. The braking resistors can be installed at the side next to the PM240 Power Modules. The braking resistors for the FSA and
FSB frame sizes are designed as substructure components. If the PM240 Power Modules of the FSA and FSB frame size are operated without line reactor, the braking resistors can also be installed under the Power Modules. The braking resistors for the Power Modules of the FSC to FSF frame sizes should be placed outside the switchgear cabinet or outside the switchgear room in order to lead the resulting heat
loss from the area of the Power Modules, thereby allowing a corresponding reduction in the level of air conditioning required. Each braking resistor is designed with a temperature switch (ULlisted). The temperature switch can be evaluated to prevent consequential damage if the braking resistor overheats.

SINAMICS G120
Inverter chassis units - Output reactors

Overview

     Output reactors reduce the voltage loading on the motor windings. At the same time, the capacitive charge/discharge currents, which place an additional load on the power section when long motor cables are used, are reduced. he maximum permissible output frequency is 150 Hz when an output reactor is used – the pulse frequency must not exceed 4 kHz. The output reactor must be installed as close as possible to the
Power Module. Output reactors are approved for use only in conjunction with "Vector" and "V/f control" modes.
