New plinth system for electronics enclosures

Louise Smyth

Rittal’s new base/plinth system for enclosures and IT racks combines the benefits of the existing TS and Flex-Block plinth systems in one solution, plus much more besides. For example, engineers can install VX25 enclosure accessories, while the plinth can also be used as an intelligent cable chamber.

All this comes with reduced assembly time, lower costs and greater safety.

The new VX25 is designed for the new large enclosure system, as well as being fully compatible with Rittal’s existing enclosure solutions, the TS, TS IT, SE, CM, PC, IW, TP and TE ranges.

As well as an extensive range of accessories, the system offers users virtually limitless options around siting, transportation, cable routing, cable attachment and plinth configuration. Its consistent 25mm pitch pattern means an enclosure’s mounting parts, such as punched sections and rails, can also be used on the plinth. So, in addition to installing baying brackets and cable clamp rails, routed cables can be easily and efficiently clamped and secured in the plinth using punched sections with mounting flanges.

This system consists of sturdy corner pieces with trim panels at the front and rear and at the sides and is available in heights of 100 or 200mm.

The corner pieces, like the trim panels, are made of sheet steel, and – due to an integrated centring aid that is pre-fitted in the VX25 frame – it is easy both to position the enclosure precisely on the plinth and install the corner pieces. Also new is the ability to attach the plinth directly from above, which simplifies screw-tightening. The plinth and enclosure frame can be screwed through the stable base frame with the aid of the nut integrated in the corner piece.

The sheet steel trim panels can then be easily snapped on and, if the enclosure needs to be lifted with a forklift or lifting truck, they can just as easily be removed again. Clip-in trim panels allow simple, fast access to the enclosure for individual use, e.g. as a cable chamber.

The system lends itself to many applications, thanks to the fully symmetrical corner pieces, and the use of the matching trim panels, along the length and width of the plinth. For example, the vented trim panels and trim panels with brush strip accessories can now be attached at the sides, or exchanged for the front/rear trim panels.  And all the trim panels can be clipped into the corner piece, or securely screw-fastened.
