Rittal’s Edge Computing, Open Compute & Open19 CPD Seminars

Rittal Ltd has developed two new accredited seminars as part of its highly-respected Continuing Professional Development (CPD) series.

Challenging  “The Edge” – IoT

The first seminar Challenging  “The Edge” – IoT looks at the rise of Edge data centres. 

It considers how the growth of cloud storage, alongside the need for higher speed and low latency, has fulled Edge Computing to support new technology such as 5G, as well as the rise in video content, and machine-to-machine learning (IoT). 

In contrast to existing data centres, which are generally sited where energy costs are lower and space is inexpensive, Edge data centres will be smaller and situated nearer users, in a mesh network.

Rittal’s pre-fabricated modular mini data centre is a complete pre-fabricated solution on a mini scale, which can be placed close to data sources.

Rittal CPD Seminars 2018

Open Compute Project & Open19 Project

The second seminar entitled Open Compute Project & Open19 Project explores the Open Compute Project (OCP), which was launched in April 2011 by Facebook in order to share their hard earned know-how to build low-cost, highly efficient data centres particularly those used by hyper-scale cloud platforms.  

The main thrust is to radically alter the way power is distributed to the server by switching to locally derived DC power, lowering power requirements and increasing airflow around the components, thereby reducing cooling costs.  Rittal’s Open Compute Project racks are a standard design, which accommodate different DC supply voltages. 

A core philosophy is that any participants who want to have a server, or other hardware, recognised as OCP-compliant must open source it.

Alongside this is LinkedIn’s Open19 project, aimed at smaller data centre operators who are smaller in size, but which house the majority of the world’s IT infrastructure. Open19 focuses on edge computing alongside the core data centre hardware, and unlike OCP, uses uses a licensing framework that lets companies protect their IP while still being actively involved.

The seminar explores Open19 hardware, which is built around the standard 19“ rack such as Rittal’s TS IT.  IT also explores how Open19 operates with a similar ethos to OCP in that it rearranges server hardware to enhance airflow through the components.

VX25 Enclosure Transition Made Easy

Rittal is supporting control and switchgear engineering as it transitions to Industry 4.0 and adopts its new VX25 large enclosure system.

The new VX25 conversion assistant for parts lists (www.rittal.com/vx25conversionhelp) provides free data and an intelligent selector and configurator, simplifying the transition from the TS 8 enclosure system to the new VX25 large enclosure system.


Control and switchgear manufacturers wanting to improve productivity, in line with Industry 4.0, need high-quality data to deliver the results they are looking for.

The new Rittal VX25 large enclosure system does just that, providing high-quality data for every process along its value chain – from electrical planning through mechanical design to manufacturing.

A variety of web-based software tools are available from Rittal so that companies can quickly, easily and precisely convert to the new enclosure system.

Converting parts lists at speed

Parts lists from the earlier TS 8 enclosure system can now be easily turned into VX25 parts lists with the VX25 conversion assistant. TS 8 parts lists from projects that are to be used again simply need to be loaded into the conversion tool as an Excel file, using drag and drop.

If the selection is based on the model number and quantity, the VX25 parts list will be provided with just one click. It also automatically displays any items not relevant to the VX25.  The converted parts list can be simply downloaded or placed in the shopping cart for online ordering. TS 8 Model Numbers can also be entered individually and corresponding VX25 Model Numbers along with additional product information, will quickly be found.

Plant constructors are also given support in converting from TS 8-based 3D enclosure layouts to VX25 system technology in EPLAN Pro Panel projects. The entire process of replacing TS 8 enclosures and accessories with VX25 articles is virtually all automated.

Data for all common CAD systems

Rittal provides further help with the easy and free download of detailed, validated CAD data in more than 70 formats, which allows the transmission of data to all common CAD systems.


The EPLAN Data Portal can be employed to load macros of the VX25 bayed enclosure system for mechatronic engineering using CAE/CAD and for generating 3D enclosure layout with EPLAN Pro Panel.  Moreover, Rittal offers data for the VX25 for classification as per eClass (Advanced) and ETIM.

Selecting and configuring products with ease

The VX25 selector means it’s easy to select Rittal enclosures along with the corresponding accessories for appropriate applications. The enclosure types can be populated to suit individual requirements with a pre-selection of common accessories.

The web-based configurator, Rittal Configuration System, offers simple and error-free configuration – even without prior CAD knowledge – of the VX25 and the desired installation components.

The tool facilitates the configuration of free-standing enclosures and bayed suites based on the VX25 – a task that is “plausibility checked”.  So, while accessories are being placed, the system will automatically check if the selected components can be placed at the chosen location.

The Configuration System also supports machining, because the configured data package contains both the parts list and a CNC program for the Perforex machining centre, as well as a 3D step model of the complete enclosure including the accessories.  It means the data about the enclosure flows directly into the machining processes. The configured items can be ordered directly via the linked online shop, which makes the ordering process even easier.

Cable Management & Future Rack Developments

There are a number of key areas for IT and data centre managers to consider when it comes to planning future rack developments.

One of the most critical is deciding the precise configuration of the internal components. This typically underpins the success of the whole project, especially when IT racks are not installed in a standardised data centre environment.

Meanwhile, choosing which rack to install requires an understanding of its purpose, the routing of cabling for power supply and networks, and the ideal cooling solution.

Here is a summary of some of the key questions to ask to help ensure the success of any future installation and commissioning of racks.

What will the rack be used for?

The number and type of components will have an impact on the size of the rack. If it will simply be used to house servers, then an IT rack 600mm wide will suffice.

However, if it is primarily for network components, the rack should be 800mm wide to accommodate the cabling.

But, increasingly, enterprises are combining server and network components within individual IT racks.

As IT takes on an increasingly significant role within organisations, more and more components are packed in to make best possible use of existing infrastructure. This means the largest available racks should be selected in line with space constraints. An IT rack that is 42 units high, 800 mm wide, and 1,200 mm deep provides ample room for custom configurations, and allows for future expansion.

What form of climate control is needed?

Will the rack be installed in a room that does not have an integrated cooling system?  If so, then a suitable cooling system needs to be considered from the outset.

If just a single IT rack is needed then cooling could simply be roof-mounted fans or, if a greater cooling capacity is required, then a compressor cooling unit can be added, either externally or internally, in the form of a DX system – although a higher IP rated rack will be required.  DX systems are becoming more popular as they are relatively easy to install and can be deployed in office environments thanks to the low noise levels of the internal component.  Should the rack be deployed in a conventional DC, with either perimeter cooling units or InRow cooling units adjacent to the racks, then perforated doors should be used.  Additional benefits can be obtained here by also deploying aisle containment or cocooning, where either the cold or the hot aisle (or in some cases both) is enclosed.  The major benefit being lower operating costs and more efficient cooling (better delta T).

Sealed Up?

There are various options for cooling IT rack interiors depending on their use.

For example, inside server enclosures the cool air should flow from front to back, while in network enclosures it should be directed through the parts that need to be cooled.

In both scenarios, it is important to seal around the front 19″ section to ensure cool air does not leak into the ‘hot zone’ at the rack rear and thus lower the delta T across the rack.  All open U’s should be closed off with simple 1U snap-off section blanking plates for effective separation. To this end, there is a range of accessories available to enhance cool-air routing, enabling horizontal airflow for side ‘breathing’ switches, and more.

Effective seals and climate control solutions tailored to the IT rack’s specific purpose will translate into improved energy efficiency. A little bit of planning goes a long way when it comes to reducing energy costs for IT operations.

Where do you want your cables?

A detailed plan for interior and exterior cable routing should be in place before a server enclosure is purchased and configured.  The power supply, in particular, has to be considered. Many active IT components require a redundant power supply which generally means two rack-mounted vertical power distribution units (PDUs) at the rack rear, left and right for an ‘A’ and ‘B’ supply respectively making cable management a bit more complex. Moreover, best practice usually recommends power and copper data cables should be kept physically apart to avoid the unlikely possibility of electrical field interference. Special attention must be paid to the minimum bend radius of the fibre-optic cables to prevent signal attenuation.

If the racks are to be placed on a raised floor, then power and network cabling can simply be laid on separate cable trays underneath. You can also mount cables under the ceiling and route them above the top of the racks. In this scenario, the roof plate needs to be configured correctly openings should be closed off with brush strips creating a tight seal, simplifying cable management, and improving energy efficiency.  It also means that even after cables have been installed, accessories (including roof plates with multiple parts) can be easily removed for simpler maintenance and retrofits.

Many rack vendors offer a choice of elements for effective cable management, enabling customised component configurations. Both open and closed cable duct systems are available for horizontal and vertical cabling, and cabling between thermal zones.  

Typically, air-tightness and a defined air pressure must be maintained to prevent warm air and cool air from mixing. This important consideration is often built into the design of many rack vendors enclosure products.  The enclosure supports the need for air circulation in conjunction with the corresponding cable installation components.

And external cable management?

Crowded IT racks have little available space to squeeze in new components. One answer is to route cables outside the racks such that cable ducts pass through the side of the rack, routing cabling over the top so that it re-enters the rack from the opposite side.  Although this approach can save a great deal of space, it may make identifying individual cables more difficult, and maintenance work more complicated.

Wherever easy maintenance is a priority, cables should be routed inside the racks. Pinpointing and replacing a single cable is then far simpler if there is a failure or if a reconfiguration is required.

Recent developments

Innovative products are now becoming available for in rack cable management.  One of these seems quite interesting: the Network Cable Organiser (NCO).

The NCO is a 482.6 mm (19″) cable storage system. It takes up 1 U in the network enclosure and contains 24 tested CAT 6, Class E patch cables or fibre-optic cables, each with a length of 1.6 m (sufficient for 23 U). It has a modular structure and is made up of individual cassettes. The pulley system integrated into the cassettes allows surplus cable lengths to be drawn in automatically which ensures that every cable is available in the perfect length, eliminating the need to order and stock a variety of different cable lengths. The result is permanently well-organised cable management, providing a perfect overview of what is connected where.

It’s also more energy efficient, avoiding airflow blockages that can arise as a result of surplus lengths of the individual cables inside the enclosure facilitates more efficient cooling. And the NCO saves on space, because it only requires 1 U per switch. Cable management panels are not required, saving additional space, while the flat cables used in the NCO only use one-third of the space of a round cable. The flat cables still offer the same level of reliability, are 100% tested, and the fibre-optic cables additionally have a measurement record on the cassette.

A Base for Every Season

Rittal’s new base/plinth system for enclosures and IT racks means it can now offer customers and end-users an unprecedented number of functions and options.

The latest innovation combines all benefits of the existing TS and Flex-Block base/plinth systems in one solution, plus much more besides.  For example, engineers can install VX25 enclosure accessories, while the base/plinth can also be used as an intelligent cable chamber.

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

The new base/plinth system VX25 from Rittal 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.

The new system combines all the functions and benefits of the Flex-Block and TS base/plinths, which it will soon replace.

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

This base/plinth 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 200 mm.

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 base/plinth and install the corner pieces. Also new is the ability to attach the base/plinth directly from above, which simplifies screw-tightening.  The base/plinth and enclosure frame can be screwed through the stable base frame with the aid of the nut integrated in the corner piece of the base/plinth.  As an alternative, engineers can screw through the base/plinth into the enclosure’s 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 base/plinth 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.

Pre-assembled captive nuts allow fast and simple assembling. Depending on the application, users can dispense with the trim panels between bayed enclosure suites, or, alternatively, a 100 mm high trim panel may be used to stabilise the base/plinth corner pieces.


The VX25 is the first enclosure system that has been fully developed to meet the requirements for increased productivity in control and switchgear manufacturing and along the Industry 4.0 value chains.

It is a major innovative leap, requiring more than 25 registered property rights, and one which reflects both Rittal’s deep industry experience as well as years of intensive customer dialogue.

The VX25 offers the highest possible quality and consistency of data, reduced complexity and savings in time, as well as safe assembly.

Rittal Publishes UL Regulations Advice

Rittal embraces the need for a high degree of responsibility for the safety of users and the electrical equipment its enclosures are designed to protect.  As such the company has a policy of always being on the front foot when it comes to fully complying with international regulations.  

In the USA and Canada, for example, a machine cannot be commissioned until approved by the AHJ (Authority Having Jurisdiction) to confirm compliance with the valid regulations, such as the National Electric Code NEC (NFPA 70).

The importance of UL regulations cannot be understated for any company exporting electrical equipment into these territories.

UL regulations relate to the protection that enclosures must provide to the internal electronic components.  This includes environmental factors such as dirt, dust, humidity and electromagnetic interference. Control gear and switchgear manufacturers should always take care to ensure that these safety standards are met for any components they are shipping to the USA or Canada.

Rittal Publishes UL Regulations Advice

For enclosure manufacturers such as Rittal, compliance with UL 508A is an important basis for the swift commissioning and approval of equipment and machinery, and the company offers a broad spectrum of industrial enclosures with UL approval. Most have UL approval with a Type 12 protection category (NEMA12); some enclosures with enhanced sealing protection even support Type 4x applications.

Rittal has recently published advice and support for engineers who are designing or specifying systems in line with UL508A, covering all the expectations and requirements for compliance.  Details are available to download from www.rittal.com/uk-en/content/en/unternehmen/presse/pressemeldungen/pressemeldung_detail_55232.jsp.

Are Your Enclosures Giving You Heat?

Manufacturing automation systems are delicate and very expensive pieces of kit, which perform vital functions for the businesses they serve.

The enclosures that protect them must have strictly controlled internal environments with interior temperatures that are carefully maintained within a few degrees.  If not, the impact can be harmful to the inverter drives, power supplies, contactors, PLCs and other electrical and electronic components operating within them.  This requires careful control of the climate within the enclosure.

With the current warm weather getting us all hot under the collar; Rittal offers some practical tips on how to evaluate an existing enclosure climate control through a series of simple checks.

How to check your cooling_3

Like all electrical equipment, drives create heat and they therefore have a major influence on the temperatures inside enclosures. Drives are often quoted as having efficiency of 97 per cent, so one with a rated output of 150kW can produce as much as 4.5kW of heat.

As well as the heat loss inside the enclosure, ambient temperatures within a production facility will also have an impact on the temperatures that a drive is operating within.  A typical enclosure climate control system is designed for an internal enclosure temperature of 35°C. This means that the performance of a cooling unit should be specified so that the average internal enclosure temperature of 35°C can be guaranteed under all load conditions and under all the ambient conditions that could be met at the machine’s location.

Checking the enclosure temperature
The first check is to measure the temperature within the enclosure to assess its climate control capability. Temperature sensors should be placed in a position within the airflow of the enclosure, sensors should not be placed on or near direct airflow from high temperature components. Otherwise temperature readings can be found to be inaccurate. The sensors should be left to monitor the temperature trend over a period of time.

If the sensor records air temperatures of well over 35°C (set point) then the output of the cooling unit should either be considered insufficient or, alternatively, that there has been a malfunction of the cold air routing in the enclosure. This means that the cooling air cannot reach (or can only partially reach) the temperature-sensitive components.

How to check your cooling2


Checking the control behaviour of cooling devices
Another easy way of checking an enclosure climate control system is to observe the cooling unit’s control behaviour.

Unlike speed-controlled cooling devices such as the new Rittal  “Blue e+” cooling units, conventional enclosure cooling units begin with the two-point regulation of the cooling operation when a temperature inside the enclosure gets above of 35°C and finishes when the shutdown temperature of 30°C is achieved (at a typical hysteresis of 5K).  If a cooling device does not reach the shutdown temperature, a conventional cooling unit will therefore continue to operate. If this happens, it’s a good indication that the cooling unit has an insufficient output and suggest that there is likely to be a deficiency in suitable cooling air to the components inside the enclosure.

You can simply touch a device to determine a refrigerator’s operating status: the activity of the refrigeration compressor during cold production is accompanied by a slight vibration of the refrigerator housing that can easily be felt.  Alternatively, the exhaust temperature of the cooling unit in the external air circuit may be measured.  During active cooling operation, this will be significantly higher (potentially, anywhere between 10° and 40°C) than the ambient temperature.

Locating hotspots
You can also do a rough check of an enclosure’s climate control system with infrared thermography which measure the surface temperatures of the components inside the enclosure and these are recorded with an infrared camera.  If any areas have significantly elevated temperatures (“hot spots”) it is an indication that they are not being supplied with enough cooling air.
