Purge Panels

[CADPRO22]

When connecting more than one panel to a purge system (Class 1 <15ft3) that is in a classified area, do the panels have to have the purge lines coming in from the side of the panel on the top and exiting the opposite side of the panel on the bottom, vice versa, or both on bottom , both on top??

Thanks in advance,
CP

Need more info. Is the purge system used for keeping vapor out of the enclosure you only need an inlet with a pressure regulator. If purge system is for vapor control and enclosure cooling most likely need inlet and outlet lines. I never seen purge systems on the top of the enclosure, mostly on the sides.
What type gas is being used for purging
Check with local AHJ before doing anything.
Hope this helps,
