Mounting
Caution
You must encase the SCX 920 in a UL approved cabinet to keep its
Open Class rating.
1. Before you begin, look at the front of the SCX 920 cover.
Figure 1 shows the front of the SCX 920.
2. The front cover of the SCX 920 has two Phillips head quarter turn
fasteners aligned down the center, one above the middle and one at
the bottom. Remove those fasteners, holding the cabinet firm so it
does not fall.
3. Remove the cover and place it to one side.
4. If you want to disable the manual overrides, proceed to the next
section and return here when you are finished. Otherwise, continue
with the next step.
