Control cabinet construction
according to UL508A

Whether control cabinets, power cabinets, terminal boxes, control panels or electronic assemblies – we are the holistic electrical partner at your side. We offer series and special productions, from material procurement to mechanical processing, assembly, wiring and testing of the system.

How our control cabinet team supports you

Electrical control cabinets, or switchgear, form the core for the operation of electrical machines or systems. In a control cabinet, PLC components, switching and control components are connected to each other. It ensures trouble-free and safe operation of machines and systems.

We offer control cabinet construction as an electrical service. It begins with the development or construction of a switchgear and ends with the scheduled wiring of the control cabinet.

We manufacture individual cabinets, row cabinets, control panels, terminal boxes in compliance with the standards and regulations for control cabinet construction. On request, we can also build and test your cabinet according to the international standard UL 508A.

We take over both the production and the engineering (project production). Alternatively, we also manufacture control cabinets according to already completed engineering or material provision by the client (customer production).

Control cabinet production

Material procurement

The choice is yours: Either we take care of the procurement of your components or youprovide us with the material in whole or in part.

Mechanical processing

All our control cabinet housings and mounting plates are processed in our milling center.

Pre-assembly & population

During pre-assembly, the control cabinet is populated and prepared for electrical wiring.

Wiring and labeling

The control cabinet is wired and labeled according to the circuit diagram – according to customer specifications also with single-core labeling.

Measurement and testing

After production, a measurement and testing of the control cabinets is carried out in accordance with the standards.

Further services

Cable assembly

Assembly of cable sets and system cables.

Module-/
Electrical assembly

Assembly, wiring and mounting of electromechanicalassemblies, devices, modules and machine frames.Complete machine installation.

UL testing and certification

The UL certification according to UL 508A is a standard that has been established by Underwriters Laboratories (UL) for the electrical circuitry of industrial control systems. The certification is sought by electricians and engineers. This ensures that their circuits and controls meet safety standards and regulations.

As an internationally operating company in automation technology, we not only design and test our own control cabinets according to the American UL standard 508a. We also offer the assessment and electrical design of switchgear of all types as a service. The development and production is carried out by our in-house experts.

Advantages of a UL508A certification

Safety

The UL508A standard provides safety, especially in environments where the risk of electrical faults and fires is increased.

Legal certainty

In some countries, a UL certification is part of a regulatory requirement.

Competitive advantage

The certification shows that you guarantee safety and quality - a clear competitive advantage.

High-performance control cabinets with copper rails

On request, we use high-quality copper rails when building your control cabinet. These offer some advantages:

Power distribution: Copper rails distribute electrical power safely and efficiently and allow multiple components to be connected to a common power source.
Space saving: Compared to individual cables, copper rails reduce the space required and facilitate the wiring and installation of electrical components.
Heat dissipation: Copper rails have good thermal conductivity, which contributes to the effective regulation and dissipation of heat.
Flexibility and expandability: Copper rails allow a flexible modification of the control cabinet without extensive rewiring.
Safety: Copper rails reduce the risk of electrical faults.

Our process chain in control cabinet construction

Needs analysis and planning

We record the requirements and specifications for the control cabinet (e.g. required number and type of components, protection classes, space requirements) and create a project plan.

Construction

Our engineering team creates circuit diagrams and mechanical layouts for the control cabinet, based on customer needs.

Component selection

We select suitable electrical components (e.g. contactors, fuses, relays, switches, terminals). In addition, we decide on suitable control cabinet housings and mounting plates.

Documentation and handover

We create a documentation of the control cabinet, including circuit diagram, parts list, operating instructions and maintenance instructions. Then we hand over the finished control cabinet to you.

Mechanical preparation

We prepare the control cabinet housing (e.g. drilling holes for components, mounting plates, ventilation, etc.), mount the mounting plates and other mechanical components in or on the control cabinet.

Testing and quality assurance

We perform functional tests and continuity tests to ensure that all components are properly wired. We also check the protective measures and safety devices.

Wiring

We wire all electrical components according to the circuit diagram and install cables, wires and cable ducts. Then the connection to the corresponding terminals and points takes place.

Population of the control cabinet

Then the required electrical components and parts (e.g. switching and control devices) are installed and installed in the control cabinet.

Fully automatic milling with highest precision

With our Perforex milling center, we modify components of almost all compact and large control cabinets. Plates and cabinets can be clamped into the machine to perform a wide variety of machining operations.

Based on CNC data, the Perforex automatically mills individual openings and cutouts in mounting plates, which are then assembled to form the control cabinet. This allows cables and connections to display or control elements to be routed through the openings.

The fully automatic milling process saves valuable time and has a much lower error rate than manual processing. This allows us to deliver control cabinets in outstanding quality and precision.

We are thinking about the future and investing in our electrical apprentices

Apprentice project:
“From the circuit diagram to the finished switchgear”

With the project “Apprentice control cabinet”, SPIE AUTOMATION specifically promotes the technical expertise of its apprentices (electronics technician for industrial engineering) in Pfullendorf. The apprentices receive the housing, circuit diagram and parts list of a cabinet and are allowed to assemble, wire and label it independently. Finally, the cabinet is checked again by an expert and corrected if necessary. It was a “real” control cabinet, i.e. our apprentices can finally be happy about the knowledge that their work now provides a real added value to a customer.
