Experts:
 
I have been told that:
 
'if you have two safety components in the same electrical cabinet you can 
connect them with a single control wire, you can exclude faults against that 
wire as a fault that needs to be considered for safety calculations.'
 
It is logical if the two safety components' are redundant.  But if they have 
different functions?
 
I have not been able to confirm that in any standard.
 
If you agree that this statement is correct, then I would appreciate your 
rationale and if possible a reference to chapter and verse in a standard or 
risk assessment document.
 
Thanks,
 
Steve Brody
