What are control cabinets with Sinamics G120 variable speed drives
A control cabinet with Sinamics G120 AC drives combines high-quality panel construction with smart motor control technology. The Sinamics G120 from Siemens is a modular inverter that precisely controls the speed and torque of electric motors. This makes it ideal for applications where energy efficiency, precision and safety are important.
At Kwadrant IA, these controllers are integrated into custom panels designed entirely in EPLAN P8/Pro Panel. Thanks to this approach, each design is clearly documented and easy to maintain. The panels comply with all relevant standards, such as NEN-EN 61439 for distribution devices and NEN 1010 for electrical safety.
Important standards and guidelines
NEN-EN 61439
This standard describes the structural and electrical requirements for distribution and control cabinets. Kwadrant IA designs and tests all panels in accordance with this standard to ensure electrical safety, mechanical strength and heat dissipation.
NEN 1010
This standard lays the foundation for safe electrical installations. By following the regulations for wiring, grounding systems and protective devices, each control cabinet meets national safety guidelines.
UL 508A
For export projects, Kwadrant IA also builds panels to UL 508A, meeting the requirements for North American markets.
ATEX 114 (2014/34/EU)
In environments with a risk of explosion, the control cabinet can be designed in accordance with ATEX 114. This makes the cabinets suitable for zones 1 and 2, where gas or dust explosion hazards are present.

Applications in industry
The Sinamics G120 is used in a variety of industries where frequency control is crucial:
- Pumps and fans in HVAC and water management systems
- Transport systems in logistics facilities
- Mixing and dosing lines in the food industry
- Compressors and turbines in petrochemicals
- Robots and drive shafts in mechanical engineering
The controller is suitable for both simple speed control and complex process automation, and can communicate with PLC systems via protocols such as Profinet, Modbus TCP and OPC UA.
Advantages of control cabinets with Sinamics G120
- Energy efficiency: Through frequency control, only the required power is supplied.
- Modular construction: Easily expandable and low maintenance.
- Communication power: Supports multiple industry protocols.
- Reliable operation: Built-in safeguards and thermal protection.
- Safety: Applicable within PL and SIL methodologies for machine safety.
The combination of Siemens hardware and Kwadrant IA’s engineering warranty ensures a panel that performs reliably under any operating condition.
The process from design to commissioning
- Design and engineering – The process starts with a complete EPLAN design that complies with NEN-EN 61439 and customer or project specifications.
- Construction and assembly – In the workshop, all components are carefully assembled, wired and checked according to NEN 1010.
- Testing phase (FAT/SAT). – Prior to delivery, Kwadrant IA tests the panels internally (FAT). An SAT follows on site to verify that the system works perfectly with the installation.
- Installation and cabling – Connection and field wiring are provided by experienced technicians.
- Commissioning and delivery – The control is optimized and delivered with a test report and declaration of conformity.
This systematic approach ensures that every control cabinet with Sinamics G120 is reliable, safe and ready for long-term deployment.
Years of experience in the field of industrial automation
Industrial automation with international standards
Industrial automation requires more than just a correctly constructed panel. We start with the architecture of the system and make conscious choices in component selection, standardization and scalability. By fully mastering engineering, panel construction and integration, we realize control systems that perform reliably in demanding industrial environments. From modular construction to international compliance, every detail is focused on quality, longevity and manageable Total Cost of Ownership.
We do not build standard solutions, but technically sound systems that match the complexity of modern mechanical engineering.
