Case study

WAGO Connectors – a Way to Simplify the Installation of 31 Control Cabinets

Project Name
Control System for an Automated Potato Processing Line
Industry
Food Processing
Scope
As part of a comprehensive project for a food processing plant, the PROPOINT SERVICES team carried out the prefabrication of 31 control cabinets, which were then transported to the client’s site and installed on the upper floor of the production hall. Each cabinet was interconnected for both signal and power, forming a fully integrated control system. Additionally, busbar bridges were integrated, and the entire installation was prepared for further works in the packing and dough preparation areas.

Challenge

The greatest challenge was the unusual location – an upper floor of the building, where it was impossible to deliver complete, interconnected cabinets as a whole. Due to the large number of planned interconnections between the cabinets, it was necessary to develop a solution that would enable fast, error-free, and safe assembly on site. Traditional methods were not an option due to the risk of mistakes and strict time constraints.

The key requirement was the implementation of a technology ensuring reliable connections despite transporting the cabinets separately.

Technologies and Solutions

Schneider Electric modular devices Siemens frequency inverters and controllers Rittal enclosures PLS busbar bridges – enabling high current capacity with compact installation WAGO spring clamp connectors and pluggable/test-disconnect connectors (734-308, 734-108) – ensuring fast, reliable, and error-free cabinet-to-cabinet connections A transport and integration system enabling single-cabinet installation while maintaining the completeness of the entire setup

Process and Implementation

The project began with the prefabrication of 31 control cabinets designed for five automated production lines processing potatoes – from French fries to potato pancakes. Each cabinet was designed with logistical constraints in mind, considering installation on an upper floor.

The use of pluggable WAGO connectors allowed for quick and secure wiring connections directly on site, without interfering with the pre-assembled installation. The cabinets were manufactured in our production facility, where each underwent complete electrical and mechanical testing, ensuring reliability before shipment.

Results

The use of pluggable connection systems significantly reduced on-site installation time

Full repeatability and quality of connections from the prefabrication stage were maintained

The risk of wiring errors during interconnection was eliminated

Installation on a hard-to-access floor was made possible without compromising quality or safety

The entire system was prepared for subsequent project phases according to the investment schedule.
