Mounting
Location Considerations
Follow these guidelines when mounting an NAE55:
•
Ensure that the mounting surface can support the
NAE55 and any user-supplied enclosure.
•
Mount the NAE55 in the proper orientation (
).
•
Mount the NAE55 on an even surface in wall mount
applications whenever possible. If you must mount
the NAE55 on an uneven surface, be careful not to
crack the wall mount feet or housing when tightening
the screws. Use shims or washers to mount the unit
securely on the mounting surface.
•
Mount the NAE55 in areas free of corrosive vapors
and observe the environmental limitations listed in
the
section.
•
Do not mount the NAE55 on surfaces that are prone
to vibration, such as duct work, or in areas where
electromagnetic emissions from other devices or
wiring can interfere with NAE55 communication.
•
Allow sufficient space for running cable and wire,
making terminal connections, and accessing battery
compartment (
•
Do not mount the power supply below the NAE55.
On panel or enclosure mount applications, observe these
additional guidelines:
•
Do not install the NAE55 in an airtight enclosure.
•
Mount the NAE55 so that the enclosure wall or the
transformer does not obstruct ventilation of the NAE55
housing.

Mounting Space Requirements, mm (in.)
Each NAE55 application is different, and no general
guidelines can be given about the heat dissipating devices
that may be mounted in an enclosure with the NAE55.
Monitor the NAE55 processor temperature for each
application to determine the acceptable combinations of
devices and proper mounting location for your specific
application.
Important:
Do not add any devices to an enclosure with
an NAE55 that could cause the temperature
of the NAE55 processor to exceed 70˚C
(158˚F). View the NAE55’s CPU

Commissioning Guide (LIT-1201519)

Mounting the NAE55
Wall Mount Applications
To Mount the NAE55 on a vertical surface:
1. Mark the location of the four wall mount feet on the
wall using the dimensions in
and an
orientation shown in
, or hold the NAE55 up
to the wall and mark the hole locations.

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 NAE55 on the screws with the top wall
mount feet for horizontal wall mount applications. Hold
the NAE55 in place for vertical application.
