NEMA Rating
The OMI5000 Series Open HMIs are rated for NEMA 4 (indoor). This means that when the Open HMI is
properly mounted to a panel or other enclosure, the front enclosure of the Open HMI will provide
protection to the inside of the panel from splashing water, windblown dust, or hose-directed water. The
computer must be installed according to the instructions in this chapter to be properly sealed.

Environmental Considerations
The OMI5000 Series is designed to operate in temperatures from 0-45° C. It is intended for indoor
installations and not designed for outdoor applications. Avoid installing the OMI5000 Series in
environments with severe mechanical vibration or shocks. Do not install the computer in enclosures
with rapid temperature variations or high humidity. Either will cause condensation of water inside the
device and eventual damage to the computer.
