Wall Mounting (optional)
For some applications, you will find it convenient to mount the
EDS-505A/508A on the wall, as shown in the following figures.
STEP 1:
Remove the
aluminum DIN-Rail
attachment plate from the
EDS-505A/508A’s rear
panel, and then attach the
wall mount plates with M3
screws, as shown in the
figures at the right.
⇒
STEP 2
:
Mounting the EDS-505A/508A on the wall requires 4 screws.
Use the EDS, 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
EDS-505A/508A downwards, as indicated. Tighten the four screws for added
stability.
