DIN-rail Mounting
The aluminum DIN-rail attachment plate should already be fixed to the back
panel of the switch when you take it out of the box. If you need to reattach the
DIN-rail attachment plate, make sure the stiff metal spring is situated towards
the top, as shown in the figures below.
STEP 1:
Insert the top of the DIN-rail into the
slot just below the stiff metal spring.
STEP 2:
The DIN-rail attachment unit will
snap into place as shown below.

Wall Mounting (optional)
For some applications, you will find it convenient to mount the NI UES-3880
on the wall, as illustrated below.
STEP 1:
Remove the aluminum
DIN-rail attachment plate
from the NI UES-3880’s rear
panel, and then attach the
wall mount plates, as shown
in the diagram below.

STEP 2:
Mounting the NI UES-3880 on the wall requires 4 screws.
Use the switch, 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 all the way—leave about 2 mm to allow room for
sliding the wall mount panel between the wall and the screws.
