BANG!

At the risk of leading this thread astray for a moment, Robert Atkinson2 said yesterday here that all VFD's should be in enclosures. I quite agree. I have two I would like to out into enclosures but can't find any the right size. Before I make some out of perhaps plywood with perspex front, does anyone know of a good source of enclosures for VFD's of all sizes?

During a previous life as an x-ray service engineer I was tasked with changing a high voltage "tank" in a hospital x-ray room that had developed an internal switching fault. (This was basically a large steel tank filled with oil and containing a high voltage transformer and switch gear.) The installation was ancient (valves and relays etc) and consequently the company had to source from somewhere in the Balkans.

I followed the standard procedures for setting the correct waveforms for the tube output and had set the oscilloscope to trigger on the final test at maximum current and voltage. As I pressed the exposure switch there was an incredible bang and a blinding flash from the control console that I was kneeling behind. The full output of 30kW @125kV had shorted inside what turned out to be a faulty tank with the result that part of the control cabinet was damaged.

My eyesight returned to normal quite quickly and the ringing in my ears subsided, but my bowel problems persisted for some time!

I bought an enclosure from TLC for my mill VFD, the panel was supplied with the door hinged on the right with the gland plate on the bottom, the door is swappable to get the gland plate and your preferred hinge side. I have a local branch so easy to collect. They have a website so you can peruse the sizes and prices. TLC Electrical

A removable backplane is most desirable and not always included, most of us are pressed for space but specifying an enclosure that is as small as possible can be difficult to work on. A removable backplane means the inter component wiring and the fixing of the components can be done out of the box. Consider how to replace components without having to strip the whole backplane out, tapping the backplane rather than using nuts and bolts will help. Nut inserts can also be useful for fixing to the backplane, plastic slotted trunking can keep things tidy and also consider using top hat rail for component and terminal mounting, many control devices will have the option for rail or direct mounting.
