[Elecraft] KPA-1500 PSU mounting position

[Bob]

Well maybe this requires a reply from Elecraft.  They seem to be furnishing 
conflicting information on this. I asked that question and here is the reply I 
received:



Elecraft:  Placement of the power supply can be anywhere within the 5.5 ft 
distance of the power supply cable and control cables, both of which are 5.5 ft. 
  Air passing through the power supply is from left to right in a horizontal 
manner.  This means that it will not work properly standing on its side.


Seems logical that setting it on the side would restrict the air flow severely. 
I'd have liked to place mine vertically on its side but did not based on this. 
Mine sits  under the desk on a riser so I did not lose foot space.  I did not 
require easy access to the switch as I totally kill the equipment circuits in 
the shack at shutdown.

The reply was that there would be no problem mounting the PS vertically, so long as the air clearances are observed for the air flow -- I believe it's three inches at the top and at the rear, but the manual is pretty clear on that.  I've mounted mine that way.  When sitting on its side the On-Off switch is conveniently near the top-rear edge.  Works FB.
