Is it Frequency Inverter a critical part in your application

What is implied when a piece of equipment, process or design is classified Mission Critical?
The answer for this question will differ for each and every organization or business, because it first has to be determined what the mission of the particular organization or business is.
Strange as it may seem, it is unfortunately true that many businesses cannot adequately define what business they are in, and whilst it may seem sufficient to state that something is "Mission Critical" if it will cost the business loss of profit or cash flow or reputational damage, the fact is each and every organization must first know what their mission is and ensure that the crucial aspects of the systems they operate, the designs they employ, the equipment they choose and the procedures they use will ultimately meet their stated mission.
So if we accept that a business does actually know what business they are in (other than the obvious "making money", or not for profit involvement in "saving lives" etc) and can differentiate between what aspects of their systems, designs, equipment and procedures are significant, important or "mission critical" then that business is well placed to undertake a ground up approach to ensuring that those aspects which are truly mission critical are adequately designed and implemented at every level and integrated throughout the structure.
For example, a kitchen exhaust system may not be mission critical to a small family run country restaurant where some cross flow ventilation can be achieved by opening a few kitchen windows if the range hood exhaust fan fails. It would be a different story in a large multinational fast food restaurant if the kitchen exhaust fan fails and the cooking fumes and smoke fills the restaurant! They would fail to meet their mission by being unable to deliver until the problem was rectified. Now think about elegant fine dining restaurants, when customers are paying for these levels of excellence it does not cut the mustard if some kitchen fumes invade the dining area. This is mission critical and would hopefully have multiple exhaust systems in place, but nevertheless the business would be smart to have adequate back up measures in place to care of such an event.
Likewise an older office building with small windows that tenants can open in the event of an air conditioning failure; this may not be mission critical, as the solar gain on smaller windows is nowhere near as significant as modern walls of glass which cannot be opened when the air conditioning fails. It's not rocket science, to take care of such mission critical events the design should incorporate back up equipment and procedures to take care of such probabilities.
Naturally cost considerations need to be taken into account; it may be acceptable to be without comfort conditions in your office for a relatively short period of time whilst repairs are carried out, rather than have a costly level of redundancy designed into the equipment. If you are operating a CBD A grade building with its associated cost of rental, your tenants may find the discomfort caused by plant failure totally unacceptable in which case this is mission critical and should be supported by appropriate design, equipment redundancy and procedures in place to mitigate such possibilities.
On the other hand, some applications such as fire and safety are by implication "Mission Critical" whether they contribute to your bottom line or not. They simply must work reliably and continue to operate under adverse conditions. Smoke spill, floor pressurization, and fire stair pressurization are all important life saving applications closely associated with frequency inverters and consequently serious consideration needs to be given to protecting their integrity with solid proven environmental protection against ingress of dust and water and the appropriate Australian Standard AS1668. To meet the reliability implied by AS1668 we recommend frequency inverter enclosure protection against ingress of dust and water to IP66 in compliance with AS60529-2004.
