FIGURE 3–3: Product Case and Unit Labels
The 489 case, alone or adjacent to another SR-series unit, can be installed in a standard
19-inch rack panel (see 489 Dimensions on page 3–2). Provision must be made for the front
door to swing open without interference to, or from, adjacent equipment. The 489 unit is
normally mounted in its case when shipped from the factory and should be removed
before mounting the case in the supporting panel. Unit withdrawal is described in the next
section.
After the mounting hole in the panel has been prepared, slide the 489 case into the panel
from the front. Applying firm pressure on the front to ensure the front bezel fits snugly
against the front of the panel, bend out the pair of retaining tabs (to a horizontal position)
from each side of the case, as shown below. The case is now securely mounted, ready for
panel wiring.
