Mounting
Location Considerations
Follow these guidelines when mounting an NCM :
• If the NCM is to replace an existing NCM350 or
NCM361, see
Legacy NCM Replacement
Considerations .
• Ensure that the mounting surface can support the
NCM and any user-supplied enclosure.
• Mount the NCM in proper orientation ( Figure 2 ). A
horizontal mounting orientation is preferred, but the
unit can also be mounted vertically.
• Mount the NCM on an even surface in wall mount
applications whenever possible. If you must mount
the NCM on an uneven surface, be careful not to
crack the mounting clips or NCM housing when
tightening the screws. Use shims or washers to mount
the NCM evenly on the mounting surface.
• Mount the NCM in areas free of corrosive vapors, and
observe the environmental limitations listed in the
Technical Specifications section.
• Allow sufficient space for cable and wire connections
(
Figure 1 ).
• Do not mount the NCM where the ambient
temperature may exceed 50˚C (122˚F).
• Do not mount the NCM on surfaces that are prone to
vibration or in areas where electromagnetic emissions
can interfere with NCM communication.
• Do not obstruct the NCM housing ventilation holes.
• Do not mount the power transformer below the NCM.
For applications where the NCM is mounted inside a
panel or enclosure, follow these additional guidelines:
• Do not install the NCM in an airtight enclosure.
• Do not install heat-generating devices in the enclosure
with the NCM that may cause the ambient
temperature to exceed 50°C (122°F).
Mounting the NCM
Wall Mount Applications
Use the holes in the three mounting clips for wall mount
applications.
To mount the
NCM
on a wall (or other vertical surface):
1. Ensure that all three mounting clips are inserted into
the back of the NCM housing. Pull the bottom two
clips outward and snap them firmly into the extended
position (
Figure 3 ).
2. Mark the location of the three wall mount holes using
the dimensions in Figure 2 , or hold the NCM up to
the wall as a template and mark the locations.
