Understand difference between C1D1 and C1D2. Have seen many offerings for C1D1 pc's and HMI's where the unit is mounted in an XP enclosure, however the touchscreen is accessible to an operator. Would mounting a unit rated for a C1D2 environment into a purged panel (instead of an XP one) still comply with C1D1? I've seen instances where its done, but in speaking to many people some say no, some say yes, and basically no one is actually sure. I'm not sure why mounting in an XP enclosure would be necessary as the device is not 'contained' in the enclosure but protrudes through it. Hard to contain an explosion that way.:-?
