Explosion protection requirements for remote IO cabinets in explosion-proof areas
Thread Content
I have a question: for the remote IO cabinet located in Zone 2, an explosion-proof area, the entire area is subject to explosion-proof requirements. The manufacturer wants to use intrinsically safe explosion-proof design, but I have no experience with this type. What aspects should be taken into consideration when using intrinsically safe explosion-proof solutions? Is it similar to intrinsically safe explosion protection, where system-level explosion protection is required and consistency in the configuration before and after must be taken into account?
Go and learn about positive pressure explosion-proof cabinets; I hope it will be useful
There are restrictions on the use of enhanced safety equipment in Zone 1, while it should be usable normally in Zone 2.
