Wall Mounting (optional)
For some applications, you will find it convenient to mount the NI MES-3980
on the wall, as shown in the following figures.
STEP 1:
Remove the
aluminum DIN-Rail
attachment plate from the NI
MES-3980’s rear panel, and
then attach the wall mount
plates, as shown in the
figures at the right.
⇒
STEP 2
:
Mounting the NI MES-3980 on the wall requires 4 screws.
Use the NI MES-3980, with wall mount plates attached, as a
guide to mark the correct locations of the 4 screws. The
heads of the screws should be less than 6.0 mm in diameter,
and the shafts should be less than 3.5 mm in diameter, as
shown in the figure at the right.
6.0 mm
3.5 mm
NOTE
Before tightening the screws into the wall, make sure the screw head
and shank size are suitable by inserting the screw into one of the
keyhole-shaped apertures of the Wall Mounting Plates.
Do not screw the screws in completely—leave about 2 mm to allow room for
sliding the wall mount panel between the wall and the screws.
STEP 3:
Once the screws are fixed in
the wall, insert the four screw heads
through the large parts of the
keyhole-shaped apertures, and then
slide the NI MES-3980 downwards,
as indicated. Tighten the four screws
for added stability.
