I think this has to do with which of the outside pins is live ('hot') and 
which is neutral. Getting it wrong won't fry the machine, but it might 
fry you if there's an electrical fault (the fuse should always be in the 
live side of the mains, as should any single-pole switches).

What you need to do is open up the Intellec and see which pin on the 
chassis-mounted mains plug goes to the fuseholder. I think the switch 
comes after the fuse in these machines, but my Intellec, an MCS8i, is 
non-standard in that I replaced the input connector with a IEC 'kettle 
plug' type of connector, and also I have a non-standard power switch 
(replaced by a previous owner). 

Then you need to see which of the 2 available cables puts the fuse on the 
live side.
