Hello,
We need to put a PLC control panel in a Class 1 Div 2 location. Unfortunately the location is fixed, there is no way we can put this panel in a non-classified area.
The plant is in Texas and the PLC's got to withstand brutal heat. What would be our options for cooling? I believe we might be able to use a NEMA 4X panel rated for Class 1 Div 2.
I know you cannot use NEMA 4X for Class 1 Div 1, but you might be able to do it for Class 1 Div 2 if you use intrinsic safety barriers. Is my understanding correct? Has anyone done this before? This will be first time for me.
Also can you put a closed loop cooling system and still have the panel retain it's Class 1 Div 2 rating?
Thanks in advance..
