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.

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.

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	3.5 mm
the figure at the right.

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.
