Moshe:
We treat the 48V input as a secondary voltage with primary voltage
rules.  Therefore, you will have to hold to the _reinforced_ distances
for creepage and clearance.

Hello everyone,

What are creepage/clearance requirements between battery (60V nominal
which could go to 72V) 
conductors and SELV conductors? The equipment resides in "CO like"
environment.

thanks in advance,
Moshe
