SINAMICS G120P Cabinet converter cabinet units, versions A and C

With its SINAMICS G120P Cabinet converter cabinet units, Siemens is offering a cost-effective drive system on which all line-side and motor-side components as well as the Power Module are integrated into a ready-to-use standardized cabinet system.

A wide range of catalog options are available for the implementation of customer-specific configurations, which are complemented and type tested in the overall system. Special requests can be implemented on request on account of the flexible production process.

The SINAMICS G120P Cabinet is especially suitable for pumps, fans, and compressor applications on account of the special functions included in the standard version, such as pump cascading, multi-zone control, emergency mode, etc.

With its high-performance, sensorless vector control, the very ruggedly designed converter covers a wide range of applications – even in harsh industrial environments. Simple, clear engineering supports assist the correct selection of components, and thus form the basis for safe, long-term operation.

Commissioning with the Intelligent Operator Panel (IOP) integrated in the control cabinet door can be performed quickly and easily. A commissioning wizard guides the user conveniently through all the essential commissioning parameters.

There are two versions of the converter cabinet units:

• Version A (75 kW to 630 kW)
  enables all optionally available line connection components, such as the main switch, main contactor, line fuses, line filter, motor-side components and additional monitoring devices to be installed
• Version C (160 kW to 400 kW at 380 V to 480 V 3 AC and 315 kW to 450 kW at 500 V to 690 V 3 AC)
  space-saving design with line reactor and optional main switch. This particularly slimline design can be used, for example, when line connection components are accommodated in a central low-voltage distribution panel (MCC) in the customer's plant or system.

SINAMICS G120P Cabinet converter cabinet units are available for the following voltages and outputs:

Line voltage	Power range
380 ... 480 V 3 AC	75 … 560 kW
500 ... 690 V 3 AC	315 ... 630 kW

The units have degree of protection IP20 as standard. They are optionally available with degrees of protection IP21, IP23, IP43 and IP54.

• Simple, safe configuration: The SINAMICS G120P Cabinet can be easily and safely configured with the aid of operating characteristics and the SIZER dimensioning tool.
• Simple selection: Multiple options facilitate an individual customer configuration (special applications can be realized on request)
• Simple, local connection: The cabinets are tested, supplied ready-to-use, and can be easily connected – without disassembly of components.
• Simple, fast commissioning: Commissioning via the Intelligent Operator Panel (IOP) integrated in the cabinet door can be performed quickly and easily. The user-friendly guidance enables a reliably configured drive to be realized in a few steps.
• A range of field bus interfaces provide simple, diverse networking facilities. The SINAMICS G120P Cabinet can be especially easily integrated into operating, machine and process sequences via the Totally Integrated Automation (TIA) portal and other tools.
• Safe operation through comprehensive monitoring and protection functions, and a maintenance-free design. As well as complete monitoring of the electrical parameters and safe shutdown if the set limiting values are exceeded, thermal parameters are continuously monitored.
• Resource and energy saving: The SINAMICS G120P Cabinet has very high efficiency verified according to EN 50598. Energy-saving functions and the automatic pulse frequency adjustment offer the best possible energy efficiency, thus saving on operating costs with every hour of use.
• Long lived through the rugged design, for use in harsh ambient conditions and suitable system components. The protective coating of modules and l surfaces, as well as the hardest operational tests enable long-term, safe operation, even in harsh industrial environments.
• Integrated Drive System (IDS): The integration of the SINAMICS G120P Cabinet into the IDS concept offers an optimal interaction of individual components in the drive train with the highest energy efficiency and the highest possible reliability.
• EPLAN macros: EPLAN macros are available not only for built-in units but also for the customer-specific, configurable SINAMICS G120P Cabinet system. This enables the entire cabinet system to be very easily integrated into a CAE system by import.

Variable-speed drives are ideal for all applications that involve moving, conveying, pumping, or compressing liquids or gases.

This means the following applications in particular:

• Pumps
• Fans
• Compressors
