Wall Mounting (optional)
For some applications, it may be more convenient to mount the
AWK-3121 to a wall, as illustrated below.
STEP 1:
Remove the aluminum
DIN
-Rail attachment plate
from the AWK
-3121, and
then attach the wall mount
plates with M3 screws, as
shown
in the adjacent
diagrams.
⇒
STEP 2:
Mounting the AWK
-3121 to a wall requires 4 screws.
Use the AWK
-3121 device, 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.
Do not screw the screws in all the way
—
leave a space
of about 2 mm to allow room for sliding the wall mount
panel between the wall and the screws.
NOTE
Test the screw head and shank size by inserting the screw into
one of the keyhole shaped apertures of the Wall Mounting Plates
before it is screwed into the wall.
STEP 3:
Once the screws are fixed
into the wall, insert the four
screw heads thr
ough the
large opening of the
keyhole
-shaped apertures,
and then slide the
AWK
-3121 downwards, as
indicated to the right.
Tighten the four screws for
added stability.
