Re: LD11 failure?

chaps

i knew i had heard something about this about a year ago

it may be nothing, BUT i had heard that an air gap has to be left
between DIN module to allow them to stay cool

the marmitek site has something on this, i say something because it
is in flemish but here it goes

"Bij montagevan merdere Modules op een DIN rail, dient afhankelijk
van de belasting, rekening gehouden te worden met 2cm afstand tussen
de Modules om voldoende warmte dissipatie te garanderen"

i would think that 2cm is the gap required, and "warmte
dissipatie"
is heat dissipation

this may be why your units stopped working/blew

see http://www.marmitek.com/nl_site/pdf/8933.pdf

cheers
