combinations of devices and proper mounting
location for your specific application.
Important: Do not add any devices to an
enclosure with a network engine that could
cause the temperature of the network engine
processor to exceed 70˚C (158˚F). View the
network engine's CPU Temperature value
on the network engine's Diagnostic tab on
the Metasys Site Management Portal. See
Technical specifications
requirements, and refer to the Troubleshooting
section of the NAE Commissioning Guide
(LIT-1201519) for additional information.
Mounting the NAE/NIE for wall mount
applications
To mount the network engine on a vertical surface:
1. Mark the location of the four wall mount feet
on the wall using the dimensions in Figure 6
and an orientation shown in Figure 7, or hold
the network engine up to the wall and mark the
hole locations.
Figure 6: Mounting screw hole dimensions, mm
(in.)
2. Drill holes in the wall at the marked locations.
3. Insert appropriate wall anchors in all four holes
(if necessary) and insert the screws into the top
two holes. Leave enough space between the
wall surface and the screw head for the wall
mount feet.
4. Hang the network engine on the screws with
the top wall mount feet for horizontal wall
mount applications. Hold the network engine in
place for vertical application.

for ambient condition
Note: The wall mount feet are designed to
make mounting easier. When the network
engine is wall mounted in the horizontal
orientation, you can hang the network
engine on the screws with the upper two
mount feet (Figure 7).
5. Insert the screws into the lower two wall mount
feet and holes and carefully tighten all of the
screws.
Important: Do not overtighten the
mounting screws. Overtightening the
screws can crack the network engine wall
mount feet or housing.
Mounting the NAE/NIE for DIN rail
mount applications
To mount the network engine on DIN rails:
1. Mount two DIN rails horizontally, so they are
125 mm (4.9 in.) apart on centers (Figure 5).
2. Snap the DIN clips on the bottom of the
network engine to the outward position.
3. Hang the network engine on the DIN rail hooks
on the back of the network engine.
Press the DIN clips back into position to secure the
unit on the DIN rails.
Figure 7: Required orientations for Network
Engine wall mount applications
To remove the network engine from the DIN rails:
1. Snap the DIN clips on the bottom of the
network engine to the outward position.
2. Lift the network engine off the DIN rails.
