Class 1 Div 2 Enclosed HMI?
Class 1 Div 2 Enclosed HMI?
(OP)
I need to enclose and HMI& Controller inside an enclosure which is to reside in a Class 1 Div 2 environment. The HMI & Controller is not Class 1 Div 2. How can I do this and still maintain Class 1 Div 2? The HMI will not be mounted on the enclosure's lid but inside the enclosure such that the operator will need to open the box to view it.
