Is it okay to short input and output negative terminal of an isolated DC-DC converter? This kind of situation is not mentioned in the datasheets. The problem arises when a load has negative terminal connected to shield (or chassis).
If designed according to manual, the converter conforms to following standards:
MIL STD 704 (withstand of overvoltage and surge conditions)
MIL STD 461 (radiated and conducted EMI)
Do I lose those standards if i connect the load as shown on the image (orange)?
The fundamental problem is with loads that naturally have grounded enclosures (I.e almos all RF transmitters, PC etc)
