Hi,
My company is bidding on a project for which we would have to build a web handling machine that would have several motors and drives. A few of the motors would be located in a hazardous location - Class 1, Division 1, Groups C & D. Any components in this location have to be explosion proof or intrinsically safe.
I am able to locate my control panel (in which my drives would be located) outside of this hazardous location. At a minimum, I will need to run motor power and feedback (encoder) wires from each motor to its corresponding drive. I do not have much experience when it comes to explosion proof / intrinsically safe construction. It seems to me that I will most likely need some sort of physical and/or electrical barrier between the hazardous and non-hazardous location.
I was wondering if anyone here could give me a general idea of what the recommended / accepted practices are for this type of scenario. If you can tell me where I should look to read up on this in more detail, I would greatly appreciate it.
For my control purposes, I can use simple DC motors / drive boards / spreed controls, AC vector motors / drives, or even servos. My performance requirements will be easy to satisfy either way. My main concern is how to handle the hazardous location requirements.
Thanks in advance,
Paul
