In contrast, Rittal relies on the familiar "one-person assembly" method for each side of the VX25. For example, a cabinet side panel can be positioned on the frame profile, where it is held in place by a special positioning aid while the installer tightens the screws. Potential equalization within the cabinet is achieved by mounting and screwing the panels together, so all flat components such as the sides, back, and top are automatically integrated into the VX25's potential equalization system. Active operating equipment, such as fan and filter or cooling units, mounted inside or on top of these panels, also provides the necessary protective conductor connection when the panels are joined. In this case, grounding strips are no longer required.

In several areas, the new wardrobe has been optimized for quick assembly. This means the new doors can be easily hung or detached from the hinges without tools. Furthermore, it's no longer necessary to remove the hinge pins to take the door off. Once the door is closed, the hinge design prevents it from being removed. And, since the doors simply hang on the hinges, these can be changed very quickly. It's now much easier to replace them with 180° hinges. The doors no longer need to be machined, as was previously the case.

Thanks to the new, comfortable VX handles, the new locking systems can be installed or removed in just a few simple steps. No tools are required. All standard versions of the locking system are available. Electronic locking systems, which are increasingly used for enhanced security, can also be installed in the future. In this case, the doors do not need to be re-machined, as they are already supplied with cable entry points.

When installing and mounting the mounting plates in the cabinet, the job is much easier if the assembly and wiring are done before installing the mounting plate. However, previously, installing very heavy mounting plates from the front into the cabinet was often difficult: the heavy mounting plate had to be lifted by a crane, lowered through the open front, and then pushed to the back of the cabinet where it was screwed in.

Now, with the VX25, mounting plates can also be installed from the rear. Sliding guides ensure that the mounting plate can be positioned correctly after attachment.

The new sealing gasket only needs to be positioned in its exact location and guarantees the maintenance of the cabinet's protection category after assembly.

The foundation of the VX25 is its new frame profile design, which is used uniformly across all vertical and horizontal sections. Consequently, significantly fewer parts are required to install a chassis within the cabinet. Because a 25 mm grid is maintained even when multiple cabinets are joined together, expanding the cabinet beyond its initial dimensions is highly flexible. For example, cable management strips or system chassis can be mounted continuously across multiple assembled cabinets, simultaneously reducing the number of parts required and, therefore, assembly time. Furthermore, almost all screws used in the VX25 utilize the same Torx 30 screwdriver.

The 25 mm grid used in the VX25 is also used for the base and plinth. This means that virtually the same cable tie strips and perforated sections used inside the enclosure can be used.
The plinth can now be screwed in from above – from inside the enclosure – simplifying installation and ensuring a secure connection with the VX25. The plinth panels are made of sheet steel and are secured with clips; they can also be screwed in as an option. They can also be easily removed so the enclosure can be lifted with a forklift or pallet truck. Automatic potential equalization occurs when the enclosure is screwed to the plinth, eliminating the need for grounding strips.
