Mounting the NIE
Wall Mount Applications
Use the holes in the three mounting clips for wall mount applications.
To mount the NIE on a vertical surface:
1. Ensure that all three mounting clips are inserted into the back of the NIE housing, pulled outward, and snapped
firmly into the extended position
2. Mark the location of the three wall mount holes using the dimensions in
as a template and mark the locations.
3. Drill holes in the wall at the locations marked in
Figure 2: NIE Mounting Screw Hole Dimensions (mm/in.) and Mounting Area Requirements
4. Position the NIE, insert the screws through the holes in the mounting clips, and carefully tighten the screws.
Important: Do not overtighten the mounting screws. Overtightening the screws may damage the mounting
clips or the NIE housing.
DIN Rail Mount Applications
To mount the NIE on a DIN rail:
1. Securely mount a 20 cm (8 in.) or longer section of DIN rail horizontally and centered in the space.
