Has anyone come across an explosion proof standard inverter??
In order to use the inverter in explosion proof environment, I think we've to get the ex panel rather than the inverter, right??
Please advise.
Kevin Jimenez said:ckchew, What classification do you need? (i.e. Class I,II,III, Div. I,II,.?)

I'm sory, I'm new to these Explosion proof standard. The explosion proof standard is not measure in something like Exe3?
What's the diff bet Exe3 & Class 1 Div 2 (I know most of the AB PLC has this C1 D2)

I am aware of enclosures that you install inverters into that are rated for explosion proof enviroments. The glands used for cable penetration must also be rated for explosion proof.
One problem for explosion proof enclosures are that they retain the heat. Every explosion proof inverter cabinet I have seen usually has an explosion proof heat exchanger/air-conditioner installed for heat control too.
